Grade us yourself

Updated November 11, 2026, 12:01 ET. Rebuilt every trading day after the close.

Every call Helios has made is in the file below: the date, the symbol, the call at 10:30 ET, the 09:30 open, the close, the move in basis points, and the grade. The misses are next to the hits. Pull it, grade it with your own rules, publish what you find. We link every published audit on this page, favourable or not.

94% of 34 called sessions

The call landed on the right side of the open at the close. 50 sessions in the window 2026-08-31 to 2026-11-10; 62 symbol-sessions with no call. Strong calls 93% of 29. First half 86% of 14, second half 100% of 20. SPY 100% of 15, QQQ 90% of 19.

How a grade is computed

A call is RIGHT when the 16:00 close lands on the called side of the 09:30 open, WRONG when it lands on the other side, and PUSH when the close is within 5 basis points of the open, counted for neither side. A row that says NO CALL is a session where Helios declined to call; it counts in the sessions, never in the score. Prices are from the minute bars Helios records itself during the session; nothing is backfilled and nothing is revised after the grade is written.

What the file does not contain

How the call is made, the price at which it was read, its strength tag, and the rules behind the hour read. Those are the product. What you can check is whether the call was right, which is the only part that matters to a trader deciding whether to pay for it.
