The prediction is that I’ll get a large number of emails by EOD and later tonight after traders survey the damage.

Yes, some things never change. Fighting a strong  tape is a time honored tradition among many intra-day traders. Unfortunately.

A few reasons:

Many intra-day traders tend to have a short bias….you know, ‘elevator down and stairs up’…’make more faster on the down  moves’.

The fading mind-set….or regression to the mean type thinking.

Probabilities. As someone who uses Market Profile and volume profiling, I’m well aware that the market tends to be rotational about 80% of the time, and makes directional moves about 20% of the time. The traders that cling to probabilities often do really well for a period of time…during rotational times…and when the directional day comes…BAM…all those rotational profits are gone in a heartbeat. This scenario plays itself out ALL the time. Especially when the market makes nice reversals such as today.

The moral of the story here is that one can not trade by probabilities alone. This is one of the reasons why I’ve been invited to speak at an institutional investing/trading conference in Japan in June.
