Not true.Quote from retire45:

You've changed your risk:reward stats, limited the number of opportunities you will have in the market and added on another point of potential loss on a trade that isn't going to make any difference to your bottom line.
If a trade is good it will tend to hold the 2pt threshold, if it is going to retrace (and you are going to catch it you will need a 4 or 5 point stop, not a 3 point stop.
But that is a horse of a different color.
