I usually ask myself questions whenever I have consecutive loses in trading, trying to know where I'm getting it wrong. This had helped me many times to get more trading knowledge that had improved my entire trading.
Definitely a good approach.
I usually do suggest to go for root-cause analysis to find what went wrong after every losing trade.
Because, this will definitely help anyone to correct their lagging part so that they may approach perfectly in next time. Trading is continuously learning process hence when we ask questions about losing trades then definitely that will lead to find out what we need to learn to avoid losing trades.
