Quote from TriPack:
So by these two arguments buying off from a support level, particularly a well-known support level improves the odds of catching a favorable move to better than random. At least they tend to improve the win percentage, but this doesn't necessarily improve the risk/reward ratio.
Very excellent point. There are many ways a particular entry can differ from a random entry. I had been looking solely at the "cost" of producing MFE. But, what you mentioned is very important... in fact... I had noticed that trading "Trend Trader" was easy and fun, because you could tell right away if it was working, and there almost always tended to be at least a quick thrust in the direction of the trade.
Anyway I wish I had more ways to quantify the different characteristics of entries. When I go back to real $$ intraday I want to know exactly what the edge is.
