This indicator is a variation of a well known WPR (Williams Percent Range) indicator.
It is calculating a sort of 4 WPR values:
- WPR of Open.
- WPR of Close.
- WPR of High.
- WPR of Low.
Those 4 values are then combined into “candles”. The calculation is not using the original WPR calculation. Instead it is adjusted to be able to calculate these 4 values. As a result 2 significant levels are now available.
- Level 0 (which unlike the original WPR, can be crossed up in this version).
- Level -100 (which unlike the original WPR, can be crossed down in this version).
That way, by observing the levels, possible overbought and oversold states can be assessed.
