3Commas HA & MA

Uses Heikin Ashi candles and a pair of exponential moving averages. A long trade occurs when a bearish HA candle is followed by a bullish one while the fast MA is above the slow MA. Shorts follow the opposite setup. Positions are closed when price crosses the slow MA or hits the swing stop.
