The 10:30 ET day call has landed the close on its side of the open in 82% of 50 called sessions since Aug 14 (strong calls 92% of 36). The call names the side of the close, not the path.
At 10:30 ET Helios calls the session BULLISH or BEARISH, flags the call strong when the evidence is, or says there is no call. The call claims exactly one thing: that the close lands on the same side of the 09:30 open. Nothing about the size of the move, nothing about the path between the read and the close.
| Measure | Result | Sample | Window |
|---|---|---|---|
| Day call right at the close | 82.0% | 50 called sessions, SPY and QQQ | 2026-08-14 to 2026-10-26 |
| Strong calls right at the close | 91.7% | 36 strong calls | same |
| First half of the window | 83.3% | 18 | 2026-08-14 to 2026-09-14 |
| Second half of the window | 81.2% | 32 | 2026-09-15 to 2026-10-26 |
| SPY | 86.7% | 15 | same |
| QQQ | 80.0% | 35 | same |
Both halves clear 80%. That is the test every read is held to before it reaches members: at least 60% in each half of the window, with at least 25 calls per half where the sample allows. The day call is the only read in the stack that passed it on its first court. The earlier 10:00 Day Card, built from frozen pre-open inputs, graded 56% on 73 calls and stays on the public ledger as the record of that attempt.
The call now carries a second condition: it is withheld when the dealer structure at the read disagrees with the drift. The reasons and the numbers are in The day call, rule v2. The table above is the record of the original rule; the landing page and the member banner read the live rule from the record file.
The day call is a verdict on the close, not a forecast of the next hour. Graded from the read price instead of the open, the sessions in this window do not show a second leg that belongs to the call. That is why it is published as a filter, not a trigger: it tells you which side of the session to work and which side to leave alone. The next hour is the hour read's job, and it speaks only when its own record says it may.
Every call is computed and stamped at 10:30 ET and graded against the close on the SIP minute bars this site records itself, one bar a minute, never by the system that made the call. Closes within 5 basis points of the open grade as a push and count for neither side. The record file is rebuilt every trading day at 16:30 ET; the landing page, the member banner and this page read the same file. How the call is formed is not published.
