The Derivative Oscillator calculates a double-exponentially smoothed Relative Strength Index (RSI) and subtracts its Simple Moving Average (SMA) to form the main oscillator line. A secondary signal line is plotted using an SMA of the main oscillator values. Th

Overview
History referencing stores the close in a one-element float array, then plots the previous value of that array element beside the previous close. It also plots a 20-period simple moving average of the array element and the same average of close, using thick gray and aqua lines against thinner white lines in a separate pane. A final array write to a constant does not change the plotted history. There are no inputs, alerts, or trade rules.
- One-element float array of close
- Previous array value versus previous close
- 20-period SMA of array and close
- Four plots in a separate pane
- Final array write does not affect history

Third-party code. ForexR did not write, test or endorse this script, and the summary above was generated automatically from its code and README. 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.
