My major problem in trading most definitely is Poor risk management. I sometimes see myself more like a gambler then a trader. With that usually comes overtrading because i want to trade for kicks, and even losing gives me kicks. But i try to combat that by trading with at least 4h candles so the time between the swings will be longer, and i will use 1d candles too just to be sure. And naturally leveraged trading is a problem for me.
Okay here is the issue which you have pointed out yourself and that is money management. Using a 4th candle or a daily closed candle of the previous trading day won't matter if your management of your risk appetite is not normal or bad. In a football match, a coach who leaves his defense line to be bad should expect to conceive goals anytime something goes wrong upfront because the opponent is going to come after the defense. This is a simple analysis of how trade is. All the time we need to have a good management of our capital.
