VarMovAvg MT5 Indicator is based on the moving average. You can customize many options and you can also set a sound alert, colors etc.
This indicator is great for trend detection and I recommend you downloading it to try in MT5 beta testing. While converting VarMovAvg I discovered multi-colored indicator type in MetaTrader 5, which allows coder to reduce the amount of indicator buffers and increase the speed of calculation. So, VarMovAvg for MT5 has 1 indicator buffer less than the same indicator in MT4
