Easier said than done. It's hard to predict such small movements as we're seeing at the moment. It is a good strategy but you have to be calculated and strict about your decisions. If you aim to make 5% then take 5% and always have a point where you'll stop your trade and take a loss if the price is moving against you.
Usually stoplosses would have the ratio of 2:1 but still depending on your risk management on how much you would totally risk up for a possible profit target.Its true that these things are easy to advice when you do know on what you are doing compared to other traders which it is really very very hard to be done. Even pro's do still struggle on how this market moves.Basing on OP, he do active trades with minimal percentage targets. Going for shorts on time spans isnt bad compared on swing or long term.
