The keltner channel indicator in Fyers Web uses the exponential moving average as the mean and plots atr bands above and below.
However there is no option to choose a simple moving average and atr bands above and below the sma.
The free version of Tradingview gives the user an option to choose ema as input if the box is ticked in the indicator dialog box.
If the user unticks the option to use ema, then sma is used as input.
Please enable this feature in Fyers web trading terminal.
This facility is available in Kite terminal of Zerodha.
I find it very useful.
I request you to enable this at the earliest.
Thanks and regards
