The Hardest Challenge of Building a Trading Strategy?

michae andi have been playing round on composer for a while now, it's almost like an if then framework. There are past attempts at this kind of thing, and they generally didn't work. The user experience challenge of building this is harder than even the technical or legal learning of those os. So maybe you could just distil down some simple concepts for people in terms of creating stratg? Cause i've created a few on here before, and it is very easy and intuitive to do.
