None of my systems actually use TradeStation Strategies. Those seem to be intended for chart windows where you have a window for each symbol you are watching. I watch hundreds of symbols a day. I implemented all my systems as indicators and they run in Radar Screens. I have to manually keep everything in sync but it better suits my needs. I am in the process of moving to another system (possibly custom) to better handle my trading systems.
you would think this would work, but it really doesn't. at least for the strategies i do. even if my p&l curve is a 45 degree down line, doing the exact opposite is usually also negative but maybe just a bit less.
You are right, most of the time is impossible to reverse a losing strategy and make it a winning one, and that is because most of the time the strategies are not symetrical. In a simple case, like you enter the trade on a break, and have a 1% stop and a 1% profit, it might work, but I doubt you will find a consistant losing/winning strategy like that.
