This tool is new. If something did not make sense, or you wanted it to do something it cannot, say so here. Every note is read.

Markets use real prices. Each market sleeve follows a large fund that tracks it, dividends included.
Strategies are estimates, not backtests. You enter the yearly return you expect. The tool compares it with the S&P 500's average of % a year and moves the sleeve that many times as far, up and down.
Bought once and held. No rebalancing, taxes or costs. Cash earns nothing.
The crash rule's results are a backtest. They use today's revised economic figures and ignore costs. They are hypothetical.
