Quite simply, you don't know if this "system" has edge - you have not adequately researched it, not back or forward tested it, not run it under live conditions etc. You have not defined 'momentum', nor tested if your definition of it works as you anticipate, nor have you factored in costs, slippage, errors etc. I think you get the just... sorry.

However, don't take my word for it (or the word of anyone else on the internet). Prove it for yourself.
