Friends, if you are constantly failing in futures trading, you probably do not have enough rules and you make instant decisions. Stop trusting your feelings :) set strict rules for yourself. Have strict rules like I won't open more than x amount, or I won't choose leverage more than this much, or I won't trade more than this much per day.
You will acquire these through your own experiences and never deviate from your rules. Your rules may change over time, but do not constantly change the rules. You are inexperienced, never trade with high amounts. Instead of learning by losing big amounts of money, learn by losing little.
