This is our official statement of correct predictions.
Spytomorrow.com offers free (and paid) next morning SPY (S&P 500) opening pressure reading. Although there are many approaches to use this information for trading, our SPY-T methodology is an overnight swing trade. We buy options at the U.S. market close and sell soon after the following U.S. market opens. Often SPY-T traders select an automatic exit time the next day, such as 9:30, 10, or 11 AM EST.
Our main measure of directional correctness is the opening of the SPY compared to the previous day’s close. Our second measure is if the market reverses and moves into the predicted territory soon after the opening. This is common within the first 30 minutes of trading. For our use, we limit the time frame to the first 30 minutes after the U.S. market opening bell. Our archive charts show the 10am line for your convenience,
The image below is an example of an up-pressure prediction starting down with an immediate up in the first minutes of the market opening.
Although we often see our pressure reading follow through later in the morning, we feel our models are not reliable after the first half-hour of trading. In other words, a new daytime reading is required. We only offer end-of-day readings after 4 PM to the public. Members do have pressure readings during the day between 10:10 AM – 3 PM EST.
It’s common, especially in low volatility markets, for the market open to hover around zero until open. Sometimes they open a little above or a little below zero, but once the market opens, the pressure seems to take over. Although our algorithms are based on the ETF SPY, during flat markets it’s valuable to find higher IV stocks and ETFs.
Sometimes, the pressure reading from the night before does not follow through and is considered wrong. Holding options overnight can be risky. Theta decay and volatility shifts can negatively affect option prices. News is often the biggest catalyst. The fact is, we have world markets making moves overnight. Also, before the US market opens the next morning—usually around 8:30 AM—economic news is released. Such information can affect the opening or change the U.S. market mood, including the SPY.
Our goal is to support the overnight swing trader. If our pressure reading places you (and us) with the opportunity to be a stronger trader overnight through he first 30 minutes of the trading day. There are no guarantees, and results vary from trade to trade and depend on your trading skill.
The first and last hours of the trading day are the most volatile. There are lots of opportunities to win and lose money. However, once the day gets going, without new measurements, we have no idea where the market will head. Currently, we don’t have day trading measurements available to the public (5 minute readings for members).
There are times when you can walk up profits or walk down losses (maximize gains and minimize losses) if the market is moving in your favor; however, this strategy is for the more skilled trader.
Overnight swing trading is a high-risk, high-reward style of trading and may not be suitable for everyone. SPYTomorrow.com is designed to provide supportive tools, market context, and educational resources to help users become more informed and disciplined overnight swing traders
