I have been day-trading for a few years and have issues holding a position for more than 30 minutes. It doesn't matter if a position is going with me, flat, or against me. The stress just gets too high and I panic exit. I solved the mental strength problem by designing my own system and indicators for doing 5-10 minute long trades. My main chart I trade the ES with is the 1k Vol(Equivalent to the 100 Tick pretty much.) and I also watch the L2. With the market moving at a good pace with medium volatility around 10-12AM and 1-3PM EST my trades are sometimes as short as 2-4 minutes. I am only capturing 1-2 points per trade. I think that it is very important for people to program their own indicators so that they understand the math behind them. I have no confidence in trading with indicators that I don't fully understand.
