The opening range breakout marks the high and low of the first 30 minutes of the day. It buys when a 5-minute candle closes above that high and sells short when one closes below the low, with the stop at the other side of the range. It takes one trade a day and closes out five minutes before the bell.

The same rule on other stocks
The opening range breakout beat just holding on none of the five stocks we ran it on.
Same rule, other stocks:
The backtest is public. Anyone can open it and check the trades.
How we tested
We ran the textbook rules on 5-minute candles on SPY from Mar 26, 2024 to Sep 30, 2026, in the same Backtest tab you can use. $10,000, all in on every trade, no margin. Commission is $0.005 a share and slippage is a cent a share, on every fill. A position still open on the last day is counted at that day's close.
Just holding buys SPY on the first day of the test and keeps it to the end. It counts the stock's price only, not dividends.
Questions
Does the opening range breakout beat buying and holding SPY?
No. It finished at +8.1% against +46.4% for just holding SPY over the same dates.
Can I test it on a different stock?
Yes. Press "Try it yourself" to open the Backtest tab with the opening range breakout already loaded, then change the stock. Without a paid plan you can reach less history than we used, and your numbers can differ.
Can I check the numbers myself?
Yes. Open the backtest we ran and every trade is listed there, no account needed.
