SPY Tomorrow helps traders study overnight market pressure

What is SPY Tomorrow reading into the next trading session? Our free SPY Tomorrow Pressure Reading algorithmic tool is designed to give visitors an educational look at late-day market pressure in SPY, based on market data and market-structure modeling. The free public reading is typically posted on the front page after the market close (4PM ET) on most trading days. We also display recent public readings and outcomes for transparency (at the bottom of the spytomorrow.com front page), so you can review the information in context.

If you’re new, start with our free 30-day challenge on YouTube. It walks through the approach, explains the thinking behind the models, and helps you decide whether studying SPY overnight swing trading fits your goals, experience level, and personal risk tolerance

Membership unlocks deeper educational tools and model views, including The Switch, additional engine outputs, IV, hurdle rates, market tension, exclusive member content, a dedicated SPY discussion forum, and technical support for using the website. Membership does not include individualized investment advice, personal recommendations, or instructions to buy, sell, hold, short, or trade any security, ETF, option, or strategy.

Our mission is to provide educational and informational content about SPY overnight swing trading, market behavior, and market structure. We do not provide individualized investment advice, recommendations, or trade instructions

What do we measure?

The SPY Tomorrow algorithms analyze market data near the close of the trading day to estimate what we call market pressure. This reading is intended to help users study overnight conditions and think through how market pressure may relate to the next session’s open.

When reviewing any reading, always consider scheduled economic events, earnings, geopolitical developments, breaking news, liquidity, volatility, and your own risk controls.
