This indicator is probably based for the people who use HA candlestick chart and frequently have to switch between Japanese candlestick and HA candles. The worry is over with this simple indicator.
Now you can enjoy both candlesticks at the same time.
AHA allows you to have 2 EMAs (mostly used for crossovers). Default values set at 8/21 EMA which we may indicate a trend reversal.
We strongly recommend you back-test everything that you need before you start using AHA.
