```
//@version=3
study("Generalized SSL by Vts", shorttitle="GSSL", overlay=true)
// Generalized SSL:
// This is the very first time the SSL indicator, whose acronym I ignore, is on Tradingview.
// It is based on moving averages of the highs and lows.
// Similar channel indicators can be found, whereas
// this one implements the persistency inside the channel, which is rather tricky.
// The green line is the base line which decides entries and exits, possibly with trailing stops.
// With respect to the original version, here one can play with different moving averages.
// The default settings are (10,SMA)
//
// Vitelot/Yanez/Vts March 2019
//
// April 2019: added colored cloud (red=bearish, green=bullish)
