Im getting confused with regards to how lowest (and highest) works.
So I get the syntax for lowest [10](low). That will give the lowest low over the last 10 bars.
But what about lowest[10](low)[4]? What does that actually do?
That returns to the lowest previous of candles 4,5,6,7,8,9,10,11,12,13 (10 candles).
It scans 10 candles starting from the fourth previous candle.
It skips candles 0,1,2,3.
Thanks Roberto, much appreciated!
