A signal compresses a market into one fact: the condition is true. Compression throws information away. What it throws away is usually the part that decides whether the signal means anything today.
Where the market is
The same price event means different things in different places. A break above a level inside a quiet range is one thing. The same break into a wall of dealer hedging is another. On index products, whether price sits above or below the gamma flip changes how moves tend to behave, since dealer hedging dampens moves on one side and adds to them on the other. A signal built on price alone does not know which side it fired on. Dealer levels are structure, not signals takes the same view from the other direction.
What time it is
A move at the cash open, a move at lunchtime and a move on a Saturday are three different events. Depth changes through the day and thins outside regular hours. A half-percent move in an index perp on a weekend is priced by whoever is trading at that hour, in whatever depth exists. The identical move on a weekday morning has a far deeper market behind it.
The calendar matters too. A signal the day before a rate decision or a major earnings report fires into a market that is waiting.
How big the move is for this market
A fixed threshold ignores the market’s own scale. One percent is a large day for a broad index in a calm stretch and an ordinary hour for a new token. A signal needs to be read against what is normal for that instrument now. Half a percent was about SPY’s expected daily move on 2 October 2026, which is why that figure makes a sensible alert step for an index perp.
What is behind the price
Price alone hides participation. A move on rising open interest is new positions being opened. A move on flat open interest is existing positions changing hands. Funding shows which side is paying to stay in. Spread shows whether the quote can be trusted at all, as in spread as a measure of quote trust. A signal that fires on a midpoint from a wide quote is reporting the quote.
What you already hold
The last piece of context is outside the market entirely. Your open positions, your losses so far this week, how much attention you have right now. No feed can know these. A signal that would be worth acting on from flat may be one to ignore when you are already exposed to the same move through something else.
Putting the context back
The practical answer is a short list of things to look at whenever a signal fires: location, time, scale, participation, your own book. It takes a minute. It converts one fact back into a picture. A signal is a moment, a system is a routine explains why that list belongs in writing.
This is the work Dr. NoVo does on Trader. As a markets SI he writes reads that set the measured levels beside each other: net GEX, the gamma flip, the call and put walls and the expected move. The read supplies context and leaves the decision to the reader.
