This is the major issues faced by new traders sometimes due to uncertainty and wrong trades we got drawdowns on our capital how to cop up that.
Once you have got a major drawdown on your capital start working on your trades where you have made losses and how you will handle that
ASK yourself is system which i am following is not working in this market once verified start modifying your strategy if you are a system based trader.
if you are a discretionary trader immediately decrease your position sizing and start with less qty once you come and gained confidence start with full qty later this will work for you.
Use Different time frames to analyze is system is working for you in another time frame.
Change your segment and understand and find is it working for you because when i have faced drawdowns i have seen change of segment have given very good result you can try it once.
Rest is also on LUCK.
