Trading the Odds on Wednesday – July 1, 2009

ES (E-MINI S&P 500) showed a remarkable strength during the last couple of sessions. Although several negative setups had been triggered -especially the negative setup during Monday’s sessions (opening up gap fill) which supposed a close below the open-, the market almost always refused to go down when it was supposed to do, and posted higher high (then the previous session’s high) on the fifth consecutive session today.

The ES (E-MINI S&P 500) opened higher +0.14% , subsequently posted an intraday high of +0.52% above Tuesday’s close, but reversed course shortly after the open and posted an intraday low of -1.38% below Tuesday’s close, and finally closed lower -0.62% on the day , while the Nasdaq 100 closed lower -0.44% on the day.

Market breadth on the NYSE and the NASDAQ was weak with NYSE Advancing Issues/Declining Issues at 0.77, and NYSE Advancing Volume/Declining Volume at 0.45 (NYSE TRIN at 1.72), and NASDAQ Advancing Issues/Declining Issues at 0.74 and NASDAQ Advancing Volume/Declining Volume at 0.52 (NASDAQ TRIN at 1.42).

On Tuesday’s session is was especially notable that:

  • the ES (E-MINI S&P 500) posted a higher high on five consecutive sessions (then the previous session’s high),
  • the ES (E-MINI S&P 500) closed below the open after 4 consecutive sessions with a close above the open, and
  • the ES (E-MINI S&P 500) posted an outside bar with a lower close, means today’s range completely covered the previous session’s range (today’s high > the previous session’S high, and today’s low < the previous session’s low) with a lower close, and
  • the ES (E-MINI S&P 500)’ intraday high (of 926) marked the high for the last 10 sessions.

I therefore checked -as always from a historical and statistical perspective- for the market’s performance on the then following session(s) after those setups listed above (which were all triggered on Tuesday’s close) had been triggered in the past:

  • the ES (E-MINI S&P 500) posted a higher high on five consecutive sessions (Setup S1),
  • the ES (E-MINI S&P 500) closed below the open after 4 consecutive sessions with a close above the open (Setup S2),
  • the ES (E-MINI S&P 500) posted an outside bar with a lower close (Setup S3) ,
  • the ES (E-MINI S&P 500) posted an outside bar on a session where the ES (E-MINI S&P 500) had posted an 10-day intraday high as well (Setup S4), and
  • the ES (E-MINI S&P 500) posted an outside bar on a session where the ES (E-MINI S&P 500) posted a higher high on a fifth consecutive sessions  -Setups S1 and S3 combined- (Setup S5).

Table I shows the ES (E-MINI S&P 500) performance (since 01/02/1990) on the next session (in this event Wednesday, July 1) immediately following those sessions where setups S1 to S5 listed above had been triggered in the past:

2009-06-30-ES-S1-S5

Although none of those setups listed above (except setup S5 with the smallest sample size) shows a significantly above or below-average probability for a higher/lower close on the then following session, all setups are agreeing concerning their -partly significantly- below-average profit factor (sum of all profits divided by the sum of all losses) for a negative expectancy on the next session.

Table II now shows the ES (E-MINI S&P 500) intraday performance (since 01/02/1990) concerning the open, high, low, close (compared to the previous’s session close) and close versus open on the next session (in this event Wednesday, July 1) immediately following those 36 sessions where setup S4 had been triggered (the ES (E-MINI S&P 500) posted an outside bar on a session where the ES (E-MINI S&P 500) had posted an 10-day intraday high as well‘), but additionally taking into account that the ES (E-MINI S&P 500) closed lower more than -0.50% on yesterday’s session (36 out of those 90 sessions which fulfilled setup S4 mentioned above met this additional requirement).

2009-06-30-ES-S4i


Concerning setup’s S4 (the ES (E-MINI S&P 500) posted an outside bar on a session where the ES (E-MINI S&P 500) had posted an 10-day intraday high as well ) intraday stats on the then following session it is especially remarkable that

  • although the ES (S&P 500 E-MINI) showed a tendency fow a higher close and a close above the open on the last occurrences, since 02/01/1990 it managed a higher close of +1.0% or more only twice, while it lost -1.0% or more on 8 occurrences for an overall significantly below-average profit factor (0.46 compared to an at-any-time profit factor on the close of 1.07),
  • the ES (S&P 500 E-MINI) never managed a gain of +1.0% or more on the close above the open, while it closed at least -1.0% or more below the open on 9 out of 36 occurrences on the then following session,
  • the average high is 0.44% above the previous session’s close only (compared to an at-any-time high of +0.67% above the previous session’s close), while the average low is -0.97% below the previous session’s close (compared to an at-any-time intraday low of -0.71% below the previous session’s close).

________________________________

Bottom line:

With respect to Wednesday’s session and based on the respective probabilities and odds concerning those setups which were triggered on Tuesday’s close, the outlook concerning the ES’ (E-MINI S&P 500) performance is negative.

Although the ES (S&P 500 E-MINI) already closed lower on Tuesday’ session and a follow-up on Tuesday’s late strength should be expected early on Wednesday’s session, a tradable and favorable edge (intraday only) would be provided on the short side of the market in the event of any significant (!) strength before, on or shortly after the open with respect to a potential lower low, a close below Tuesday’s close and/or at least limited upside potential on the close (a close on a weak note).

Successful trading,

Frank

Trading the Odds on Monday – June 29, 2009 -intraday setup-


I posted several tweets during today’s session concerning the ES (E-MINI S&P 500) probability and odds for a close below the open on today’s (Monday’s) session.

Before I checked -as always from a historical and statistical perspective- for the market’s performance on those session(s) after the setups listed below had been triggered in the past:

  • the ES (E-MINI S&P 500) opened higher at least +0.40% (Setup S1),
  • the ES (E-MINI S&P 500) opened higher at least +0.40% AND the opening up gap was filled during the session (Setup S2),
  • the ES (E-MINI S&P 500) opened higher at least +0.40% AND above the previous session’s high (Setup S3), and
  • the ES (E-MINI S&P 500) opened higher at least +0.40% AND above the previous session’s high AND the opening up gap was filled during the session (Setup S4).

On today’s session setup S2 had been triggered during the session (the ES did not open above Friday’s high).

Table I shows the ES (E-MINI S&P 500) end-of-day performance (since 01/02/1990) on those sessions (in this event Monday, June 29) where setups S1 to S4 listed above had been triggered in the past:

2009-06-29-ESi-S1-S5

Is is especially notable that any gap fill during the session -like today- significantly reduces probability and odds (profit factor) concerning a positive close and a close above the open.

Table II shows the ES (E-MINI S&P 500) intraday performance (since 01/02/1990) concerning the open, high, low, close (compared to the previous’s session close) and close versus open on those sessions (in this event Monday, June 29) where setups S1 to S4 listed above had been triggered in the past:

2009-06-29-ESi-S2


It is especially notable that on those session where the opening up gap had been filled during the session -like today- the ES (E-MINI S&P 500) shows a significant tendency for a close below the open (on 264 out of 355 sessions), and the profit factor significantly undercuts the respective at-any-time profit factor (0.24 compared to 1.05).

________________________________

Bottom line:

With respect to Monday’s close compared to the open, this setup would call (with a historical probability of approximately 75%) for an ES (E-MINI S&P 500)’ close below 917.25 on Monday’s session.

But keep in mind: We’re as always talking about probabilities, not certainties.

Successful trading,

Frank
