Nothing predicts anything, Saltynuts. A trade is just like a chess move. Your opponent is the market. In chess, for instance, if you've got this: 1. e4 e5 2. f4 You've got a potential King's Gambit. White offers a pawn to Black in exchange for faster development. Nothing, and I repeat, nothing can predict that Black (in that case, Mr. Market) is going to accept the gambit. If it does, then you (White) know what will happen: 2. ... exf4. You then know what your options are. You're in control. Total control. That's if you know how to play chess (or the market), of course. For me, it's just the same. A trade on the market is nothing more than a single move in a game of chess. It is not deterministic at all. It's just a move. Hopefully bringing you one step closer to victory.
