Double RSI uses a Slow RSI combined with a Fast RSI to generate Buy and Sell signals. Least Squares Moving Average is only here for filtering signals. It is very good on certain stocks or ETFs on longer timeframes for swing trading. If you get a Buy signal look at the LSMA trend and if the candle is above the LSMA. It works great for me on lower timeframes scalping futures and on higher timeframes swinging options. It is better than paying for Buy and Sell signals. Its my first script/indicator so play with it and see what you think. Let me know if you guys find anything that makes it better. Hopefully this helps some traders out there.
