Close before earnings: +7.5%

The stop is judged on the close: it fired at the close of the gap day and sold at the next open. The backtest reproduces exactly that, and marks the earnings date in the trade log.

Did the rules make the money, or the hunches?

Every trade stays tied to the signal behind it. The review counts them apart: what you did by the rules, and what you did off them — and what each made or lost.

Example figures

What it does not do

No broker link, no access to your money: It connects to no broker and stores no broker password. You place trades at your broker; this is the ledger and the decision panel.
No stock tips: Every signal comes from a rule you wrote. We never tell you what to buy.
No promised returns: A backtest is history, not a forecast. It shows where a rule went wrong before; it cannot promise it will not again.
Not real-time: Prices come mainly from Yahoo Finance, mostly daily bars, with delayed intraday data. Made for decisions after the close, not day trading.

Who makes this

I build Stock Compass on my own. The BILL trade at the top is my own strategy losing money in a backtest — it is why the backtest now has an earnings calendar. The tool is still improving bit by bit; if something is wrong or missing, write to me.
