Hey,

I am trying to gauge interest in investment modeling/backtesting/optimization in order to possibly create a product that can solve them for my own use and possibly others.

I would like to ask anyone that is interested a few questions about what you perceive as the biggest challenge you face in carrying out backtesting/stress testing/optimization of your trading ideas. I know that that there is a multitude of software that does this but as far as I can see most of the software on the market is either deficient or expensive (or both). Most of the software also does not focus solely on the area of trading strategy research.
