Source Code
The code stays on GitHub. The author has not published this script under an open licence, so ForexR does not show its code. Copy script reads the file straight from GitHub into your clipboard, so you can still try it on your own chart. Ask the author before reusing the code anywhere else.
Overview
Central Bank converts each series to trillions of US dollars, subtracts reverse repo and the Treasury account from the Federal Reserve figure, and adds the other banks into one total. A simple moving average of that total is plotted on the chart's left scale. Individual series appear only in the status line. Toggles, the average length, and a plot offset control the display. The other-banks input is unused in the shown code.
- Multi-central-bank balance sheet requests
- Reverse repo and Treasury account subtraction
- Trillion-dollar US dollar conversion
- SMA smoothing of the combined total
- Status-line plots for each component

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.
