This indicator draws another pair on the chart. Its main use is to easily spot discrepancies between correlated pairs.

Input Parameters

• Symbol: the symbol code of the pair to be plotted.
• Delta Y: value added to the new pair, used to move it up or down on the chart.
• Flip Vertically: indicates whether the new pair should be inverted.
• Periods: is the number of periods to be drawn.
• Candle width: is the candle’s body line width.
