The Delta indicator draws two lines:

  • Red - the bar average price line (OHLC)/4;
  • Green - the line of the decimal logarithm of the current to previous (OHLC)/4 prices ratio.

The indicator has no input parameters.

Calculations:

Delta = Price + Diff

where:

Diff = Log10(PrevPrice / Price)
Price = (Open + High + Low + Close) / 4.0
