I just started, never did actually. I try to keep track of different setups, entry, stoploss and exit, RR, max drawdown and what happened after the trade (or why my setup did not work out).
You just think it didn't work out but you are currently on the progress. Why assumed early? Just try to move forward with your set of strategy until you reached your goal. Trading is not as easy as 1,2,3 so definitely even how wonderful our strategy is, even we applied that sort of journal thing you have mentioned, we can't see the result in just a short period of time.
My suggestion is to just continue. Building trading experience is they key to improved your trading.
Goodluck.
