Description
⋅ Very unusual trend indicator. Strange, but this idea works.
Idea
GreenBar = close > open
RedBar = close < open
Only 8 last bars are considered. Including current.
GreenBars 6, 7 or 8 of pieces from 8 last = UpTrend = Lime background
GreenBars 0, 1 or 2 of pieces from 8 last = DownTrend = Red background
