Trading the Odds on Friday – October 23, 2009

xx

At least until the end of the first hour of Thursday’s session it seemed that the trading day would be fully compliant (means a probably negative close) to the most recent market history (7 lower closes) after the the ES E-MINI S&P 500 had posted a higher high (than the previous session’s high), but closed below the previous session’s low on the previous trading day:

The ES E-MINI S&P 500 opened lower, was trading lower in comparison to Wednesday’s close at the end of the first hour of Thursday’s session, and was trading significantly below Wednesday’s close at least once during Thursday’s GLOBEX session. A trend-day up was – at least with respect to recent historical probabilities and odds – the least expected outcome (but trading is all about probabilities, never certainties).

Financials made the largest comeback on Thursday’s session, the third above +/3.0% end-of-day gain/loss during the last 10 sessions.

_________________________

The following setups were triggered on Thursday’s close:

No. INDEX SETUPS TRIGGERED
1 E-MINI S&P 500 opened below the previous session’s open and closed above the previous session’s close
2 E-MINI S&P 500
3 E-MINI S&P 500
4 E-MINI S&P 500
5 E-MINI S&P 500

* ) : –

( * the setup doesn’t provide a statistically significant edge on any side of the market)

Due to the fact that at time of writing (00:25 AM) the ES E-MINI S&P 500 hasn’t posted a (pre-opening) low of less than -0.25% on the GLOBEX session (since 04:30 PM on Thursday), I thought it would be much more interesting to show if – and to what extend – this might have any implications for today’s (Friday, October 23) session (a recovery day and bullish engulfing pattern – opening below the previous session’s close and a close above the previous session’s open after the ES E-MINI S&P 500 had posted a black candle – a close below the open – the day before has probably positive implications as well with an above-average probability and profit factor for another higher close).

Table I below shows the ES E-MINI S&P 500’s intraday performance (since 11/01/2008, one year history) concerning the pre-open low (GLOBEX until 03:30 AM), the GLOBEX (24 hour) low, the (end of the) first hour of the session compared to the previous close, the (start of the) last hour of the session compared to the previous close and the close (in chronological order) on those sessions where the ES E-MINI S&P 500 did not post a pre-open low on GLOBEX of less than -0.25% before the open (from the start of the GLOBEX session at 04:30 PM on the previous day until the open at 09:30 AM).

2009-10-22-ESi

Interesting to note that – since 11/01/2008 – the ES E-MINI S&P 500

  • was trading above the previous session’s close at the end of the first hour of the session on 43 out of 50 occurrences (and lower at least -1.0% only once),
  • was trading above the previous session’s close at the start of the last hour of the session on 41 out of 50 occurrences (and lower at least -1.0% only once, a year ago),
  • closed higher on 39 out of 50 occurrences, and lower -0.75% or more on only 3 occurrences (never since 03/23/2009, the last 38 occurrences).

The absence of any pre-opening weakness seems to be highly indicative – at least probabilities, odds and the t-scores are way above their respective at-any-time probabilities and odds – for a positive performance during all stages of the following session, and downside potential will probably be limited (to say the least).

And even in the (regular) event the ES E-MINI S&P 500 posted an intraday low (during the regular session) below the previous session’s close (on 43 out of 50 occurrences, there were only 7 occurrences where the ES E-MINI S&P 500 was never trading below the previous session’s close during the 24-hours GLOBEX session including the regular session), the market was regularly able to recoup it’s intraday losses into a positive close.

________________________________

Bottom line:

In the event the ES E-MINI S&P 500 wouldn’t have posted a pre-opening low of less than -0.25% on the GLOBEX session until todays’s open (ES E-MINI S&P 500 not trading below 1088), this would have positive implications for today’s session.

A favorable opportunity on the long side might be provided in the event of any weakness during the first hour of today’s session targeting some (significantly) follow-through of Thursday’s strength into a (probably) higher close.

Successful trading,
Frank

Summary of potentially tradable edges for Friday – October 23, 2009

DATE TIME WHAT
ACTION WHY ENTRY
STOP 1)
Pos. Size 2) 3)
10/23/2009 n.a. E-MINI S&P 500 LONG follow-through (strength)

xx
2) For position sizing, optimal f (by Ralph Vince) is utilized;

optimal f = ([( win/loss ratio + 1 ) * probability of a winning trade ] – 1 ) / ( win/loss ratio ) ;
win/loss ratio = avg. gain on a winning trade / avg. loss on a losing trade ; /% simplified version ;
Pos. Size (in $) = MAX [Intraday / Overnight Initial Margin ; Maximum Losing Trade (in $) / optimal f ] ;

Margin requirements:
ES E-MINI S&P 500 (ES): Intraday Initial Margin = $2,250 ; Overnight Initial Margin = $5,625 ;
ES E-MINI Nasdaq 100 (NQ): Intraday Initial Margin = $1,750 ; Overnight Initial Margin = $3,500 ;
Russel 2000 Mini Futures (TF): Intraday Initial Margin = $2,500 ; Overnight Initial Margin = $5,000)
xx

3) Position size in units per $xxx of marginable equity; if the E-MINI S&P 500, the E-MINI NASDAQ 100 or Russel 2000 Mini Futures are utilized, the number in brackets equates to the number of contracts, otherwise to the number of leveraged Exchange-Traded Funds (ETFs) of 300% of the (inverse) performance of the underlying index, assumed a fixed marginable equity of $100,000
