During simulated trading, position management and leverage size are controlled well
but in real contract trading, I often lose money.
Is there a master who can teach me how to make money in contracts?
Should I switch to low-leverage long-term investments to reduce the risk of short-term volatility and liquidation?
Or should I trade short-term volatility contracts and set clear stop-loss and take-profit levels?
Which one would be better?
