Quote from xiaodre:
Ostensibly this type of trading will do very well for instruments that have a lot of retracement of moves. That's basically every commodity and every forex pair. I'm going to look for books about grid trading theory now.. if any actually exist.
EDIT: just for the record, I like the grid you were running without the martingale progression better, but I don't know enough about it to make a real informed opinion. It's just a gut feeling...
