I have been trading for two weeks at prop shop and was told to start out with a 100 shares at a time. How long do you recommend sticking with that?
Until you can make consistent profits! 4 out of 5 days profitable, for two weeks straight, then increase size to 200, trade that for a week, then go to 300, trade that for a month or so, and then increase size as you grow more comfortable. Trading is a marathon, not a sprint!
