I’m always calculate my daily profit if I lose some day then I also try to recover in next day, I’m never trading in target my daily profit I’m just calculate monthly basis profit. If I earn daily 1% and I think it is perfect earning but some day I make a profit 5% but when I lose then it will be recover in my next trade and it calculate over all 15% end of every one month. As like i manage my trading profits in every month.
