I built myself a tool that analyzes my trade history and tells me the ideal risk management and trade management strategy I ought to use, assuming my entry signals stay the same. As someone who doesn't trade market structure and doesn't believe in placing stoplosses based on support and resistance it has been incredibly helpful. Seeing how helpful it was for me, I'm considering making it a Web app for users. Before putting hours of work into that, I wanted to ask: Does anyone think this would even be something they'd pay for?
Something would sell, I suppose, if it can be shown how effective it really is. Documented results, not claims. You would need to determine how to do that.
