The short version
CRTLAB found every order block behind a break of structure on the S&P 500 from 2022-07-01 to 2026-11-06: 7,703 on the 15-minute chart, about 6.2 a day. Here is how often price returned to them and broke them, next to fake zones placed at random by the same rules, and a chart that opens on the S&P 500 so you can test your own order-block entries.
What the S&P 500's order blocks did within 24 hours (measured)
Price came back to a 15-minute S&P 500 order block within 24 hours on 86.5% of zones, and broke through it on 69.2%. A fake zone of the same size, seeded the same distance from price, was revisited on 85.8% and broken on 68.0%.
If the real zone and the fake one behave alike, the block is not doing the work on its own: the edge, if there is one, is in which blocks you take and how you enter. That is exactly what a replay measures.
| S&P 500 | Zones | Revisited 24h | Fake zone revisited | Broken 24h | Fake zone broken |
|---|---|---|---|---|---|
| 15-minute | 7,703 | 86.5% | 85.8% | 69.2% | 68.0% |
Testing order blocks on the S&P 500
Open the S&P 500 with structure breaks and order blocks marked, hide the future, and take the blocks you would take: after a liquidity sweep, inside a kill zone, with a fair value gap in the move, whatever your rule is. Step candle by candle, place the stop and target, and let the journal tell you whether your version beats the fake zones.
