About the Simple Decycler Indicator
The Simple Decycler Indicator for MT5, developed by John F. Ehlers, is a trend analysis tool based on his “Decyclers” article in *Technical Analysis of Stocks & Commodities* (September 2015).
The indicator uses three distinct lines—red (top), blue (middle), and green (bottom)—to highlight market direction and potential trade opportunities.
When price is above the red top line, the market is considered bullish; when below the green bottom line, it is bearish.
Price between the lines signals a range-bound condition.
Traders can use the blue middle line as a decision point: a close above it signals a buy opportunity, while a close below it signals a sell.
Exits are triggered when price crosses back over the middle line against the trade direction.
The Simple Decycler is non-repainting, reliable, and works on all currency pairs and timeframes.
It helps traders identify trend continuation, reversals, and range-bound behavior, making it suitable for scalping, intraday, and swing trading.
