DecEMA_StDev - MetaTrader 5 Script | Forex Indicator Download - MT4/MT5 Resources

This December EMA has an indicator with additional trend strength indication using colored points based on the standard deviation algorithm.

If the standard deviation of the DecEMA indicator is between the dK1 and dK2 parameter values, a small colored dot will appear on the moving average. Its color corresponds to the current trend direction.

 Enter double dK1= 1.5 ; // square law filter coefficient 1
Enter double dK2= 2.5 ; // square law filter coefficient 2

If the standard deviation is higher than the dK2 input parameter value, the point size increases. Therefore, we get 3 levels of trend strength indication.

The indicator uses the class SmoothAlgorithms.mqh library (copy it to \MQL5\Include). The use of the class "Average price series for intermediate calculations without using additional buffers" is described in detail in the article.
