You have different data feeds from different brokers, also, the formulas for the two indicators will be different.
The formula for the SuperTrend indicator will be different than the standard Average True Range indicator.
Our ATR formula is much more complex than a standard SuperTrend indicator.
Here is a standard SuperTrend formula.,
Super-trend = (High + Low)/2 + (Multiplier) * (ATR)
Here is just a small part of our ATR formula.
if (double.IsNaN(Result[index - 1]) && !double.IsNaN(_atr.Result[index - 1]))
{
var previousATR = Weight * _atr.Result[index - 1];
IsLong = Bars.ClosePrices.IsRising();
var previous = UseHighAndLow ? (IsLong ? Bars.HighPrices[index - 1] : Bars.LowPrices[index - 1]) : Bars.ClosePrices[index - 1];
Result[index] = IsLong ? previous - previousATR : previous + previousATR;
}
