What is GMXMA?

GMXMA is an MT4 signal tool that prints arrows from Bollinger Bands and a GMMA. The original describes eight moving averages arranged in parallel.
A GMMA normally uses twelve exponential moving averages, and the original notes that this tool uses eight instead. The SMA_Period setting adjusts the period of the Bollinger Bands.
How to use GMXMA

Arrows appear when price leaves the Bollinger Bands and then comes back inside them. The original notes that the RSI filter keeps the overall count of signals low.
Signals are also shown while the GMMA is producing a clean trend and volatility is present. The Deviation setting adjusts the deviation applied to the bands.
