For the past couple of months I've backtested numerous strategies on indices and stocks (moving averages, macds, stochastics, RSI, momentum, chart patterns, options etc.) but they all seem to break down in short time frames like days or months. For longer time frames (>10 years) they seem to show some improvement in the sharpe ratios, CAGRs and max drawdowns with respect to simple buy and hold, but I'm not really interested in that at the moment. I'm mainly interested in trading in short time frames like days or months.
So just how do successful day traders even do it? Obviously conventional strategies are not going to work based on my backtesting research. Or I hate to say, is it just dumb luck to strike gold in the short term?
