This pertains to any market, but the cold trader I am referring to is a stock trader. Anyway, this individual who is a friend of a friend is just a really bad trader. Buys stocks at brand new highs, ok good. Takes small profit. When the stock has a big reversal, exits his long and goes short, then the stock goes back up!!! I have noticed that when he is in a big losing trade (relative to his account size) and is not taking his stops, holding on...holding on....etc, when he exits the position, when he stops the pain, that is a good proxy for that stock going up (assuming he was long in the trade). Question is whether this is something that can be traded as in when he exits a bad losing position, I take the trade?
