Including RSI crossovers 80/20 or 70/30 would be a great help.

Including RSI crossovers 80/20 or 70/30 would help identify overbought and oversold situations where this divergence from the stock's actual price would give you a great lead indicator as to future price movement. On Balance Volume trendlines would also be of great help.
