This indicator uses the closing and opening of the price in a way that reminds me of the indicator but it seems different. It's an oscillator with overbought and oversold zones and crossovers for entry and exits. I included the option of changing the moving averages from the standard exponential types used in its 3 functions to calculate the main and signal lines just in case the settings need to be changed further or if anyone wants to experiment to find better settings on top of just changing the lengths for each length type. I added dots for when the Main line crosses the Signal line. The Main line is darkened in case anyone needs to see it better.
