Overview

On each iteration, the script updates a persistent variable using modified closing price values, summing the output to plot in a separate pane. Designed primarily as a performance test for function invocation and local variable scope handling in runtime environments, it offers no specific directional trading signals.

Indicators describe the past, and a strategy's backtest can look better than live trading, especially when a script repaints. Check it in the Strategy Tester and on a demo account before you rely on it.
