Quote from justrading:
Well with swing trading you are hitting for the fences rather than bunting. You will be looking for at least 400 pips profit.
Anything less than 1 ATR and basically your are subject to being taken out by noise. If you are good at picking your entry spot you could get away with 1 to 1.5 ATR.
Reduce your position size so that the wider stop is within your risk limit, or else stick to day trading. I'm not sure how IB is with forex trading below the minimum size, they say it's handled differently so you'll have to check.
