You never know you're wrong in trading, you FEEL you're wrong. A lot of that is illusory because of the way highspeed algorithm trading works. Check out a 15 second chart of CL during EPI reports or in the last 5 minute of RTH, that as to be the result of HFT price action, lstop-runs are the way those firms make money.
If I sold every loss I had on the ES for -4 points or -30 points on CL because it felt like price could go lower I would be insolvent. There's no way you can cut losses frequently intraday and remain solvent, costs of trading are too high. If you try being cautiious like that you have to end up developing a trading product for income. I want to trade for income.
If you don't want to be affected by HFTs then don't trade short term. Don't look at anything less than a 5 min chart.
Hft algos don't affect swings, they only get you if trading v short term. So don't trade short term.
I'd be surprised if there are any HFTs operating in gbpusd futures-have you seen the daily volume? They can only operate in highly liquid.markets-gbpusd isn't one of them
