Backtrack

Backtrack replays real price history bar by bar and gives you the ordinary order ticket against it. You size, you set the take-profit and the stop, and you find out what that would have cost — with paper money, before you size into it for real.

The fees and the liquidation rule are the live ones, because a practice run that is cheaper than the real thing teaches the wrong lesson.
