Hey DB,
Just wonering what you did on Friday, (the 24th). There was less than a 1% gap and the market started moving down from the open. Did you trade? If so, did you still wait out the first 15 or 20 minutes? At what point did you decide a range had been established, (since it never really attempted to move up). Thanks for the reply.
Coming up with statistics for these gaps is not an easy chore. If, for example, you want to see what price did if there were no gap at all, you wouldn't find very many days that began with no gap at all unless you went back to the point where market conditions were such that whatever lessons you might learn may not even apply.
The statistics that I do have from the work of others show that the smaller the gap, the more likely it is to fill. Conversely, the larger the gap, the less likely it is to fill. As a rule of thumb, this cut-off seems to be around 2%.
What I look for in gaps is some indication of intent. If, for example, we're up 10 pts, we are more likely to fill than not, so I'll look for an entry on the downside. But if we're up only a few points, and I don't enter until the opening low has been exceeded by two points, then the gap is practically closed by the time I enter.
The easy solution to days when the gaps are small or non-existent is to wait until a range is established, then take the breakout of that range. Unfortunately, there are days when price begins to move almost immediately, and if there's no gap, the only alternative is to bracket the trade and place an even bet. This may strike some as fairly aggressive, but it beats guessing on one side vs the other, and it sure beats waiting for a half hour until whatever move there may be is nearly over.
On Friday, it seemed to me that the intent was clearly down, though the big downbar took place just before/at the open. When price pulled back on the 0934 and 0935 bars, I used the low of the 0933 bar as my benchmark, and entered two points below that at 1020.0 (0943).
Unfortunately, I moved my stop to breakeven when I was five points ahead (those are the rules) and got stopped out of the position. Since the ES did not retrace, I could have just stuck to it and let the NQ go, particularly since 1020 was the high point of that retracement, but I elected to stick with the rules. When I tried to re-enter, I got stopped out again, also for breakeven.
Events like that are a pain in the ass, and depending on the character that the market adopts, I may have to widen my stops, or wait longer before moving them to breakeven, or trade the ES and NQ simultaneously, or or or. But for the time being, I'm leaving things just as they are at least until we get off the pot with regard to Iraq. After all, there were extremely few trades last week, but that turned out to be for the best. Friday was my only disappointment.
Trying to assess the "mood of the market" at the open may not be everyone's cup of tea. And it's not exactly in keeping with "simple". However, you could use some bar other than the 15m or 30m or whatever. You could backtest the 5m bar. Or a 7m bar. Something that would get you in earlier without whipsawing you to death. I haven't backtested a variety of bar lengths, much less coupled whatever results I might get with the degree of the opening gap, if any. But if anybody else has, or has started to, I'd sure like to hear about it.
