Db,
While I was looking at the gap this morning, you fade the gap if it is > 1%. I was wondering what happens if for example instead of turning up, the NQs continued down from the low of 964.50 at 9:35. What would be done in this case?
I ask because I know that there are strong days when gaps open and continue going and was wondering what strategy is good to use for NQs when this happens.
Thanks.
I had been told that it's not a good idea to trade in the direction of the gap, but I found by chart review that that's not something that one can just accept prima facie. It just depends on why the gap occurred in the first place.
According to Frederickson's stats, the larger the gap, the less likely it is to fill. Since this was 1.5%, it was very likely to fill, and was well on its way before the Bin-Laden spike. If it hadn't, I would have gone ahead and entered the downside. However, I would have liked to see an aborted attempt to fill the gap, which would suggest a lot of downside pressure, i.e., a lot of supply and insufficient demand.
I haven't included gaps in the ORB strategy because too much depends on judgement, and there's nothing "simple" about that. But I suppose the simplest means of trading them would be to come up with a standard entry point, exit at the fill, then come up with criteria for fading the fill. Or, if fading the fill is not statistically worthwhile (determined by chart review), standing aside until the day's true trend manifests itself.
One difficulty I've had in coming up with real data on this rather than "feelings" is that there are so few gaps, particularly the larger ones, unless one goes well back into the chart record. But if one does that, the risk increases that one is comparing two dissimilar markets and that whatever data will be obtained will be irrelevant.
Therefore, if you can come up with specific criteria for trading these gaps, good for you. I hope you'll share them. If you can't, then just ignore them and allow the opening range to form itself before instituting the ORB strategy.
