The activity of sub 1 hr as per the system is difficult to test accurately without the code to automate the process. That would require the code for the original indicator etc. to accurately give a result, it can not miss trades. I have taken trades successfully on 15 Min time frame. But they have been taken off of the longer time frame set up with interpretation of where the market is at that moment, and what news is likely to drive market psychology next. To say they are valid, and what parameters (of which there are many distinct possibilities) are effective requires accurate forward testing with a full trade universe as per the rules. Anything else is pie in the sky. To do it manually for a significant amount of trades and through different market environments without missing any signals is really tough to do.
