True Back Testing

A true back testing tool similar to fxreplay.com or forextester.com would be nice as the market replay tool from tradingview kinda sucks as its very limited, hard to use with multiple timeframes at once, and its limited to how far you can go back to test.

if you need a way to get data when making the tool, you can buy some from forextester.com and export that data into a file.

Im not sure how possible this is. but, if you can have a option to save individuals trades so you can go back to them like a flash card to quickly practice saved trades, that would be very cool to have.
