To my good copy-trading brothers, starting from a 300u trade, we've already doubled the amount, so in January I increased the principal to 1500u, aiming to double it by the end of the month. I trade cautiously and will protect my principal well. I hope that brothers who follow my trades won't give various opinions since you've chosen to follow. I try to keep backtesting risks very low so everyone doesn't have to worry so much. Copy trading is by chance. If you really want to follow, I suggest sticking to 30%-50% of your own principal. Those with smaller capitals than mine should not double up, as the risk is very high. The remaining half can be traded with me in the group, so everyone's goals can be more aligned—earning a few points daily steadily, a long-term approach.
