    In order to calculate the value for the component term ( i.e. middle term) do you treat positive aspects differently from negative. For eg for simplicity if the were only 2 aspects, a square and a trine to consider and the were in full aspect on a certain date and the weight given was 1 , would the middle term be the sum of +1 and -1 =0 (because it’s a positive and a negative aspect on the given date ) or would it be +1+1=2 ( because it’s 2 full aspects occurring on the same date) ?
    I hope this makes sense to you. ;0)

    • Nick,

      At any given point in time it is unlikely that any planetary aspect is exact. For example, it is rare for a perfect trine aspect of 120 degrees to take place for any one day. Instead, it is more likely the aspect is within an “orb of aspect” (e.g., an aspect of 119.78 degrees). Therefore, rather than it being a simple “1+1=2” situation, it is more likely that it is a “0.972 + 0.995” situation. The more exact the aspect, the closer the value is to 1.0. Alternatively, as the aspect strays further away from a perfect aspect, eventually the value for that aspect reaches zero.

      Toward the end of his book Stock Market Prediction, Donald Bradley included a table with logarithmic values to apply to aspects that are not exact. These values assign exponentially less weight to a planetary aspect as it moves away from being perfect (e.g., as it moves away from an exact trine aspect of 120 degrees).

      After taking into account the “exactness” of each aspect, all the planetary aspects for the Middle Terms are calculated. Each of these aspects individually is either “positive” or “negative” in value. The value used for the Middle Terms portion of the Bradley Siderograph is based on the net “positive” or “negative” value for all of the Middle Terms aspects in the aggregate.

      For example, if the total value of all the “negative” Middle Terms aspects for a certain day is -25.7 and the total value for all the “positive” Middle Terms aspects on the same day is 12.7, then the “raw” Middle Terms value for that day would be 13.0 (i.e., the combined total of -25.7 and 12.7).

      This “raw” value of 13 for the Middle Terms is then added to the “raw” values for the Long Terms and Declinations to arrive at the “raw” value for the Bradley Siderograph itself.

    Hi , given that 2008 was such a major year for the market , it doesn’t seem like there were that many major turn dates signalled by the siderograph. Why do you think this was?

  3. brian says:

    I am new to this site so was wondering if someone can explain if the S+P is being projected to fall to 2230 by mid December of 2017 based on the posted chart? I am not really clear on how to comprehend the chart with green line going down to 2230 Dec 17 (I am assuming a projection is being made for the S+P to fall to this level).
    Thank you for clarifying,

    • Hi Brian,

      Thanks for your comment. For the Bradley Siderograph (i.e., the green line in the graph) the focus is typically on “turn dates” in the indicator (i.e., the dates when the indicator reaches a high or a low) rather than the absolute level of the indicator.

      Therefore, there is no projection about the future level of the S&P 500. Instead, the upcoming “turn dates” (e.g., December 3, 2017, January 17, 2018, etc.) represent dates to watch the market closely to see if it appears to be changing direction.

      To add some additional clarity regarding “projections,” none of the content on this site contains any investment recommendations, projections, advice, offers to buy or sell securities, etc. As I am not familiar with the unique financial situation of the users of this site, I’m unable to offer any such recommendations. That being said, I hope this site is able to help you better understand concepts covered in Donald Bradley’s book “Stock Market Prediction.”

      See below for some additional resources that might be helpful:

      The first section at the page below labeled “The Bradley Siderograph and the Advanced Astro Indicator” has some additional insights regarding how to think about the Bradley Siderograph (i.e., the “green line” in the graph you mentioned):

      Here’s a link to the specific section of the Bradley Siderograph “intro” video that provides some additional context:

      Finally, this page also provides some additional background on “turn dates”:


  4. soma says:

    Matt, is there a change of trend soon, month has gone now but no turn yet

    • Soma,

      You are correct that the S&P 500 has been trending in one direction for a long time (i.e., onward and upward with only minor pullbacks). However, as I mentioned in my comment below to Gary, eventually we’re going to see a pullback.


  5. Gary says:

    Matt,we have cit on Oct 7,and if you watched the change in trend it slowly started with iwm. Next cit is Dec 3,6 .Looks to me we correct in Oct and Nov as we never corrected in Sept

    • Gary,

      I agree that a correction is overdue and could happen in the next month or so. That being said, between now and the end of the year I’m the most focused on the December 6, 2017 Long Terms turn date with a power of 100/100. Past performance is obviously no guarantee of future results, but over the last 15 years the Long Terms turn dates with a power of 100/100 have performed relatively well.



  6. Soma says:

    Matt, just looked again at the charts and astro charts indicating top here and dwn for a while, is that correct, i cant see where the August bottom and then high into Sept. Have we seen the top or near there.

    Kunsan maybe u can explain what u are seeing and im missing

  7. soma says:


    Im still confused are u saying the bottom was MID AUGUST low and from here we see further highs. Charts are indicating we go down from here till Dec, is that not correct.

    • Hi Soma,

      The Bradley Siderograph Turn Date on August 19 with a power of 17/100 happened to be a low. However, as noted in the “Nature of Turn Dates” page, a Turn date can take place at both highs and lows in a security’s price.

      You are correct that the Bradley Siderograph declines after the Turn Date on September 7, 2017. However, the Bradley Siderograph is typically leveraged for its Turn Dates (i.e., when the Siderograph changes direction from up to down or vice versa) rather than the focus being on whether or not the Bradley Siderograph itself is increasing or decreasing. The “Nature of Turn Dates” page will probably be the most helpful in explaining this further.

      See below for a link to a graph illustrating how the S&P 500 experienced a temporary low on August 19, 2017 as well as a link to the “Nature of Turn Dates” page, which has additional details.




  8. Kunsan says:

    Apologies – I should have read your website in detail first. I can now how your calculation method differs. Congratulations in that you appear to have nailed the August 19 low and the market also appears to be heading towards an early Sept rally high.

  9. Kunsan says:

    Thanks for your interesting website. I’m confused. I have a copy of the original Bradley Siderograph book and none of the dates shown in your charts match the dates shown in the book. For instance the book shows a possible high Aug 26th then no other dates until lows on Sept 30th and October 8th. There isn’t a date shown for Sept 5th or 7th (which I accept based on your work could be a rally high).

    Is there a reason why some of the dates you use appear to be different from Bradley’s original book?

  10. Dave says:

    Gary, I had bought ( shorts ) late last week and early this week. I have been selling them off from yesterday and today. One more batch to sell for Monday or Tuesday depending on Market action. I do not get to cute with my trading trying to pick the exact lows or days. Bulls and bears make money, pigs lose out. I will be going going back long for a few days early next week until the end of the week. All the best to you.

  11. Gary says:

    Dave are you looking at Aug 21eclise as bottom on close

  12. Dave says:

    I have been short going into Aug 21st give or take a day or two. I plan on going back into the shark infested waters approx. mid week of Aug 23rd. Good luck everyone.

  13. Gary says:

    Looks like the 19th will be low,could be possible turn up on the eclipse on Monday?Sure looks like it now as most charts are looking to bottom intom the 18tg

  14. RP says:

    Hi Matt,

    Sept.5 is 17/100 declination power and Sept.7 is 29/100 Bradley power.How significant are these powers and does it mean markets can top around that time and inversion ? Thanks for your help.

    • Hi RP,

      Thanks for your comment. It’s possible a top or bottom could take place on these dates. However, given the relatively low “power” I would not personally place as much weight on these turn dates themselves. However, it’s interesting to note the significant decrease in (1) the Bradley Siderograph, (2) the declinations, and (3) the middle terms around these two dates in mid-September.


  15. Win says:

    I am having difficulty interpreting the Turn Date, Aug. 19. I was assuming the turn date meant a turn down but the chart show a definite turn up into Sept. In Sept. there look to be a significant TurnDown. Will someone please confirm or negate what I am seeing. I am new.

    • Hi Win,

      Thanks for your comment. Turn Dates can have “inversions,” which is where a bottom in the siderograph corresponds to a top in the price of a security or vice versa.

      For example, on April 17, 2017 there was a low in the Bradley Siderograph with a power of 19/100. This Turn Date took place at a high in the Bradley Siderograph, which corresponded to a low in the price of the security (i.e., the S&P 500). This would be an “inversion.”

      Therefore, the upcoming Turn Date on August 19 could correspond to a top in the S&P 500, which would be an inversion.

      I hope this helps, but please reach out if you have any additional follow up questions.


  16. soma says:

    Matt, is the top for s&p in July/August

    • Hi Soma and Gary,

      The Advanced Astro Indicator for the S&P 500 tops a little later in the summer than the pure Bradley Siderograph itself. Right now the market has some bullish signals (e.g., new highs) as well as bearish signals (e.g., small cap stocks underperforming large caps). Therefore, regardless of what any one indicator might point to, I personally like to take into account a variety of factors when assessing the market.

      The Bradley Siderograph has matched the S&P 500 quite closely for the first half of this year. However, as you may have heard me say many times, past performance is no guarantee of future results.


  17. Gary says:

    June 30 turndate and now July4th turn,so is July 4th a high anyone???

  18. jim says:

    Matt, thank you for your outstanding work !!!!! all hail bradley and MATT

  19. Jack says:

    Great job Matt right on the number,WOW

  20. Enrico says:

    Hi Matt how should I manage all these turn dates coming up from tomorrow onwards till the 4th of July two of which are 100/100!!
    Is there possibility to have huge volatility in the spx?
    Thank you Enrico

    • Hi Enrico, Jack, Gary, and others — thanks for your comments. I just released a new YouTube video that goes over the June 21, 2017 Bradley Turn Date with a Power of 100/100. One of the key highlights is that the Advanced Astro Indicator also appears to show a top for the S&P 500 in July (i.e., shortly after the top in the Bradley Siderograph for the year).

      Also, if you’re curious about how the “Power” for the Turn Dates is calculated, feel free to check out a comment I just left for Vikalp on the “Formula” page that provides an overview of what goes into the calculations. See below for the links.



  21. Gary says:

    Matt or anyone else have any input into all these upconing turbs in June July?June9th,21,30 July 4th

  22. Gary says:

    Matt June 9rh 61/100 top?June 21st 100/100 bottom.June 30 100/100,July 4th 100/100 top.Lot of big moves,in short period of time.What does your roadmap look like?Thanks Gary

  23. jack says:

    Thanks Gary, I was long going into March 20 and on the 17 I loaded up my long position. Thanks to Matt and Bradley. Any pull back on Bradley dates maybe chance to go long. Good luck, thanks Matt.

  24. bebe rebozo says:

    Hi Matt, This may be off topic, but does your work show any correlation between the middle terms and gold stocks as measure by the GDX ?
    GDX made a significant low on Dec. 20, 2016, a significant high on Feb 8 and a possible major top four trading days ago on April 13.
    Thanks Matt.

    • Hi Bebe,

      For the GDX, historically a Middle Terms Turn Date with a power of at least 59/100 resulted in a turn 76% of the time. Specifically, 76% of the time the GDX’s direction in the 17-18 days before the Turn Date was the opposite of the price direction in the 17-18 days after the Turn Date. However, please note that past performance is no guarantee of future results, and this comment (and the site more broadly) does not contain any financial, legal, or other advice. Click here for a screen shot of the results. Also, click here to see the specific Middle Terms Turn Dates I used for this analysis for the GDX.


  25. Gary says:

    Jack,i agree,no sell in May and go away all though next week should be down

  26. Jack says:

    Hi Matt, Thanks again for the great analysis. I just went long Spy yesterday at open. I expect a small pull back in last part of April then go until the 100/100 June date. Jack

  27. Gary Lutz says:

    April 17 turndate and April 19 turndate is this one big turn up?,,

    • Hi Gary,

      Given the relatively low Power of 19/100, I’m personally not too focused on the April 17 Bradley Siderograph Turn Date. The April 19th Middle Terms Turn Date with a Power of 59/100 could be similar to the previous two Middle Terms Turn Dates at the end of December 2016 and January 30, 2017.


  28. Mark says:

    Hi, are the long term dates the most significant, or most powerful data points (100/100) for a major market change shown in your analysis?
    Thanks for the great work.

  29. RP says:


    Thanks for your reply and help.April 17 (19/100) turn:Do you see up turn or more down turn?

  30. Gary Lurz says:

    Thanks Matt,i believe we go down into April 15-21then turn up into gov mess April 28-29 which should be a top

  31. Gary Lurz says:

    Matt what do you expect from next turndate.I see we have April 3,17,19,29?.April3 turn to the upside April 17-19,then a turn down into 29 (debt ceiling 28)

    • Hi Gary,

      Thanks for your comment. I’m looking at the April 3rd Turn Date as a “turn within a turn.”

      The S&P 500 reached a plateau from the beginning of March until the March 20, 2017 Turn Date with a Power of 100/100. The day after this Turn Date (March 21) the S&P 500 dropped 1.24%, which was the largest one day drop since mid-October of last year. The S&P 500 then proceeded to decline further, and as of today (April 8th) the S&P 500 is still below where it stood at 2,373 on March 20. To summarize, the March 20th Turn Date was a relatively significant top in the S&P 500, and overall the S&P 500 has been declining since then.

      However, as we started to get closer to the April 3 Turn Date the market decline paused. After March 27 the S&P 500 began increasing until it reached a minor top around the April 3 Turn Date. The April 3 Turn Date appears to be a top similar to the one on March 20, but because of its lower power (i.e., 30/100 for April 3 vs. 100/100 for March 20), the top marked by the April 3 Turn Date is relatively small in comparison.

      Sorry for the delay in my response, but I hope that helped!

    • Meron says:

      Very well done and presented Matt! Although the signals were there, I was sceptic yesterday. Also, I wasn’t quite sure it will take place on the exact date.
      Thank you for putting this together and taking the time to present it to us!

  33. Jack says:

    Matt, Superb analysis so enlightening but as an option trader my personal interest lies in a shorter time than 29 days say 5-10 days. Thank you so much for the great work, even for an option trader your analysis is very helpful. Thaks, Jack

  34. jim says:

    Matt, GREAT PRESENTATION !!!!! thank you

  35. Gary Lurz says:

    Matt seems we were going from 3/2 to 3/14 than turn on 15th could this be the early 3/20 turn to the upside in to 4/17 turn?

    • Hi Gary,

      As you noted, after topping at the beginning of this month the S&P 500 has experienced some weakness over the last couple of weeks. If the March 20 Turn Date happened to be a “Middle Terms” Turn Date I would be more focused on short-term changes in trend. However, given that this is a “Long Terms” Turn Date, I would expect it to represent a change in the longer-term trend in the S&P 500. It very well could be that we could see some upside leading up to the 4/17 Bradley Siderograph Turn Date. However, based on the long run up in the S&P 500 since early November 2016, I’m personally looking for a topping pattern or some weakness in the S&P 500 around and after the March 20 Turn Date.


  36. Patrick says:

    Regarding the 100/100 turn long term turn date on 3/20/17. . . Novice to Bradley. At 10/100 and the market continuing up can I assume this is a pivotal move to the down side from here?

    • Hi Patrick,

      Thanks for your comment. As you noted, the March 20, 2017 Turn Date for the Long Terms could coincide with a change in trend. Given that the S&P 500 has been in an uptrend, this change in trend could be a turn to the downside as you noted.

      I just completed an analysis of the extent to which the S&P 500 actually experienced a change in trend historically during previous 100/100 Long Terms Turn Dates. I’m going to record and send out a link to the video within the next day or two. If you haven’t done so already, I encourage you to sign up for free email updates so you can receive the results of this analysis when I send it out. Look for a box on the right-side of the main page (bradleysiderograph.com) where you can provide your email address to subscribe.


  37. jim says:

    Matt, which of the 3 terms middle, long ,declinations are considered to have the most energy ?

    • Hi Jim,

      Thanks for your comment. For longer-term changes in trend in the S&P 500 I personally prefer the Long Terms, which are based on the planetary aspects between the slower-moving further out planets (e.g., Jupiter, Saturn, etc.).

      I’ve noticed that the S&P 500 frequently changed its trend on or around these dates in recent years. The most consistent trend I noticed is that the S&P 500’s trend in the month (i.e., 31 days) leading up to the 100/100 Long Terms Turn Date has tended to change direction in the subsequent month (i.e., 31 days) after the Turn Date. See below for the most recent 100/100 Long Terms Turn Dates:



  38. Gary Lurz says:

    18 we turn up?Matt what do you think?

    • Hi Gary,

      A number of the Middle Terms Turn Dates with a power of 53 and higher called turns relatively well including the following:
      October 17, 2014 (S&P 500 bottom)
      May 24, 2015 (S&P 500 top)
      February 6, 2016 (S&P 500 bottom)
      August 8, 2016 (S&P 500 top)

      Over the last couple of weeks the S&P 500 appears to have reached a temporary plateau in a trading range between 2269 and 2277. We reached this level after a 3 stage rally (i.e., a significant post-election upturn for most of the month of November, a smaller “Santa Claus” rally for the first coupe of weeks in December, and an even smaller rally for approximately the first week of this year). Overall the key takeaway from this is that the weakness in the S&P 500 over the last couple of days has been relatively small when compared with the significant upturn that led up to where we are right now.

      It is definitely possible that the S&P 500 could continue to rally, which would be supported by the strong uptrend since early November. As they say, “the trend is your friend,” and it’s usually a good idea to think twice before going against the overall direction of the market. That being said, from a Turn Date perspective, overall I see the S&P 500 as having increased significantly leading up to the January 18 Turn Date. Therefore, the relatively modest market weakness we’ve seen over the last couple of days could continue if this January 18 Middle Terms Turn Date signals a top.

    i follow your blog and ytube religiously even though i understand a very little at age 70+ but again thanks for running such a great blog
    with that said what is your thinking about last comment by Peppinger that June 2017 looks quite interesting

    i will thank you for making it simple as much as possible but still quite interesting and educational

    • Hi Vick,

      Thanks for your comment. For 2017, the largest cluster of significant Turn Dates appears to take place between June 21 – July 4:
      June 21 – Bradley Siderograph 100/100 Power
      June 30 – Declinations 100/100 Power
      July 4 – Middle Terms 100/100 Power

      Therefore, this time period could be “quite interesting.”


  40. jim says:

    Thank You for your very hard work and the great presentation

  41. Jack Cooper says:

    Matt, Great work thanks so much. Question: Have you ever noticed a double consecutive inversion in the past with 100/100 bars? Thanks again, Jack C

    • Hi Jack,

      Thanks for your comment. On July 27, 2006 there was a high in the Bradley Siderograph with a Bradley Bars power of 100/100 that corresponded to a low in the S&P 500. Several months later on December 17, 2006 there was a low in the Bradley Siderograph with a Bradley Bars power of 100/100 that took place at approximately the same time the S&P 500 was making a high.


  42. Srinath says:

    Thank you Matt for the update. These charts looks great!!

  43. Peppinger says:

    I like the new style very much!

    • Peter,

      Thanks for your comments. I’m glad you like the new format. The response for the new format has been very positive, so I’m planning to roll this format out to the rest of the securities by the end of the year.


  44. Peppinger says:

    Hi, Matt!
    Thanks a lot – you are doing a great job!
    On a quick view – for me the end of June 2017 looks most interesting – 3 x 100%!!!
    Have a good time and lucky trading!

    • Hi Peter,

      I completely agree — the Turn Dates taking place at the end of June and beginning of July appear to be the most interesting of the year. I look forward to seeing the market’s activity then!
