Like so many things, this is up to your personal judgment, but many traders wouldn’t enter a trade unless they thought they had a chance of making 2 R profit.You need your average win to be be bigger than your average loss, so that you have a good chance of coming out ahead in the long run.Again, you need to be realistic.If you are trading over a period of a week, and your target gain needs the stock to go up by 5%, but its normal range over a week is 2%, then you don’t really have an expected gain of 2R.
