The algorithm’s overnight pressure reading posts before the close for members.
Day traders go flat. The overnight session — and the information flow that drives it — begins.
Global markets, futures, and news reprice SPY while U.S. screens are dark.
The gap resolves. You review how the reading scored — every result is logged publicly.
See Exactly How the Overnight Readings Work
In this webinar, Rosh walks through the overnight gap phenomenon, how the pressure readings are generated, and how members use the tools to build their own research process.
SPY readings are typically posted free after the market closes (4:00 PM ET) and are available before the close for members. Readings are informational and may change; you are responsible for verifying market conditions and making your own trading decisions.
Why the Overnight Session Is Worth Studying
This isn’t a “secret system.” It’s a well-documented structural feature of modern markets — and SPYTomorrow exists to help you study it with better data.
A Documented Market Phenomenon
Academic research has repeatedly found that a large share of equity index returns has historically accrued between the close and the next open — the “overnight session.” Most retail traders never analyze it because they only watch the market during the day.
A Regime-Aware Reading, Not a Hunch
Our proprietary CV engine analyzes dealer positioning (gamma exposure), options flow, and market regime to classify each overnight setup — then publishes one clear pressure reading per day. No screen-watching, no dozens of alerts.
One Decision a Day
The overnight structure fits real life: review the reading near the close, do your own analysis, manage your position at the open. It’s a research framework designed for people with jobs, families, and better things to do than day-trade.
Every Reading Is Published. Every Result Is Scored.
Most services show you their winners. We log every reading — right or wrong — against a published scoring standard, and keep the full archive open to members for independent back-testing. Judge the data yourself.
See How We Score for the exact scoring methodology and History for the archive. Historical results are informational only and are not a guarantee or indication of future performance.

The Reading — Before the Close

The Full Signal Stack
Go beyond the headline reading: GEX (dealer gamma exposure), confidence numbers, hurdle rate, and regime context — the same metrics the engine uses.
Complete Archive for Back-Testing
