Some excellent comments in this thread. My advice to OP: trade one contract, once a day. That will force you to only go for the very best setup. Of all the factors to consider, your desire to make $400/day is the least relevant. I can promise you that you will go broke trying to trade 50 times a day, unless you have a well-tested auto trading app. You will inevitably take some big losses that will wipe out your small profits. But seriously, WTF do I know?
1. Trade 1 contract once a day. Do not hold overnight. Give it at least 6 months. 2. Scale to 2 a day. Trade Max. Twice a day. 3. Graduate to 3 lots a day. Trade twice a day. Once you get to # 3 which should be in a year's time. Consider yourself in the club. Trading is more about discipline and controlling your emotions.
