Does buying gold at yesterday's low work? Backtest (last 30 days)
The rule, in plain words
Each day we look at gold's lowest price of the day before. If the price drops below that level and, within the next three 15-minute candles, closes back above it, we buy. The stop goes just under the lowest point of that dip (20 cents below), the target is twice the amount risked, and any trade still open is closed at 20:30 UTC.
Over the last 30 days this rule lost money: 13 trades, 31% won, −2.9R.
R = units of risk: +2R means you won twice what you risked on each trade, −1R means you lost what you risked.

How it is calculated
1-minute data from the TraderWAI market feed. Entry at the close of the 1-minute candle where the rule is met (the same engine that runs live conditional orders). If one candle touches both the stop and the target, the stop is counted (worst case). No spread, commissions or slippage.
Past results don't guarantee future ones. Not financial advice.
Questions
What is a backtest?
It applies a fixed rule to past prices to see what would have happened: which trades it would have taken and how each one ended. It tells you how the rule behaved, not how it will behave.
What does R mean?
R is the amount you risk on each trade (the distance to the stop). +2R is a win of twice that risk and −1R is a full loss. It lets you compare results without depending on account size.
Can I change the rule?
Yes. Ask your AI for the same backtest with another market, period, stop or target. On the free plan you can test the last 7 days; longer periods are available on paid plans.
