The reason most people find it difficult to trade from both directions is because they don't alter their targets for each scenario. If you only use one timeframe, then "counter-trend" movements, by definition, have less reward for the same risk (your risk really shouldn't change just because it's trend or counter-trend). Exits should be taken sooner in a counter-trend scenario. And if you aren't tracking these trades to ensure a positive expectancy, then you're not playing the game like you should. If you are fading a move on a higher-timeframe, then you can get the reward where it needs to be and can have more confidence to hold for a larger target. Keep trading.
