Accuracy Log

How this is scored. Each weekday morning the dashboard’s gamma flip level and its two biggest magnet strikes are recorded. After the close, that day’s high and low are pulled and judged: HELD means price never crossed to the other side of the flip level it started on; BROKE means it did. A magnet counts as touched if the session’s range reached that strike.

Known bias. A daily bar carries no intraday timing, so the high and low include the part of the session before the snapshot was taken. That slightly over-counts both breaks and touches. It is a real limitation of free daily data, not a rounding detail.

! BLOB_READ_WRITE_TOKEN is not set, so stored data is written to an ephemeral filesystem and will be lost on the next deploy. Create a Blob store in the Vercel dashboard to make it durable.
