Quote from abattia:
OK, fair questions; apologies for not having been clearer...
By "Trading the Opening Gap" I guess I meant placing a fading trade in a given instrument at session open, based principally on the fact that there is a "gap" a) between the instrument's closing price in the last session and b) the price at which it opened in the current session.
I guess the key point is that you are using the fact that there is this "gap" as principal trigger for your trade (although there might be other "filters", too).
