Similar to Bollinger Bands, this indicator plots a center moving average with upper/lower bands offset by volatility (often an ATR multiple). Typically a 10-day SMA of typical price is center, with bands at the average 10-day range above/below. A close above the upper band is seen as bullish; below the lower band is bearish. Forex EAs use Keltner breaks to signal strong moves. Implementation involves combining an MA and ATR; for example, MQL4 can use iMA()
and iATR()
, while cAlgo has Indicators.KeltnerChannel()
.
