If it happened that you lost most of the money, then you need to stop trading and begin to do an analysis of all trade transactions. You need to understand the mistakes.
The thing i will do when i lose a lot of money in trading is i will still not stop on trading, i will just focus more and i will bounceback more stronger so i can able to come up with my loses, and for me losing in trading is normal so the best thing we can do is to be more better trader.
