Bar Price Change Difference - 2 Chart

This study calculates the bar to bar price change for two charts which are used in the calculation and then calculates the difference between the result of those two price changes.

Chart 1 is the chart to which this study is applied, and Chart 2 is the chart specified by the Chart 2 Number Input. Let \(C^{(1)}_t\) and \(C^{(2)}_t\) be the closing prices of Charts 1 and 2, respectively, at Index \(t\). Then we denote the Bar Price Change Difference - 2 Chart at Index \(t\) as \(\Delta (\Delta C_t))\), and we compute it for \(t \geq 1\) as follows.

\(\Delta (\Delta C_t) = \left(C^{(1)}_t - C^{(1)}_{t - 1}\right) - \left(C^{(2)}_t - C^{(2)}_{t - 1}\right)\)

When finding the corresponding bar in Chart 2, a nearest match using the Date-Time is used.


  • Chart 2 Number: This input specifies the Chart Number of the second chart used in the calculation.
