Smoothed Sensitive MA is triple weighted for price changes.
It takes in one parameter "Length", which is used as both
1. the lookback period for price change,
and also as
2. the number of periods to be averaged
Alternatively, you could modify the script to use two separate parameters for values for 1 and 2.
In true TradingView spirit, the author of this script has published it open-source, so traders can understand and verify it. Cheers to the author! You may use it for free, but reuse of this code in a publication is governed by House Rules. You can favorite it to use it on a chart.
