This indicator shows a close approximation to what Gunbot would use in its GAIN and STEPGAIN strategies.
The middle two lines are the EMA(2h) and EMA(4h) lines. The inner two grey lines are BUYLVL2/SELLLVL2, the outer grey lines are just there to constrain the color bands. The green and red bands are indicators of where the candle has exceeded your setting and Gunbot would start considering buying or selling.
