The Leading Indicator was created by John Ehlers (Cybernetic Analysis For Stocks And Futures pg 235) and as the name implies, this is a leading indicator that provides super early signals. Feel free to change the alpha values to adjust to your needs. Buy when the indicator line is green and sell when it is red.

The version for MetaTrader 4 will not be presented here. You can download it along with the source code through my Telegram channel. The link to the channel is in my profile. Don't forget to subscribe!
