The i-CAi indicator with additional trend strength indication using colored dots based on the standard deviation algorithm.
If the standard deviation of the i-CAi indicator is between the dK1 and dK2 parameter values, then a small colored dot appears on the moving average. Its color corresponds to the current trend direction.
input double dK1=1.5; // Square-law filter coefficient 1 input double dK2=2.5; // Square-law filter coefficient 2
If the standard deviation becomes higher than the dK2 input parameter value, then the dot size increases. Thus, we get 3 levels of trend strength indication.

Variation of the SMI indicator based on the "Momentum, Direction, and Divergence" book by Blau.ZZLevels
The ZZLevels indicator uses the Simple ZigZag to find the boundaries of the flat, as well as the support and resistance levels.
