A perp on a stock or an index puts several figures in front of you at once. The order you read them in matters, because the early ones decide how much the later ones are worth. This is a working sequence. None of it produces a trade. It produces a clear statement of what the market is showing.

Start with the contract

First, which book. The same ticker can list on more than one, each with its own price and open interest. Name the book before quoting anything, as one ticker, several books explains.

Second, what hour. If the stock market is open, the perp has a live reference. If it is shut, the perp is trading alone. A weekend reading and a weekday reading of the same field mean different things.

Then the weight

Third, how big. Look at open interest and 24-hour volume. A deep market’s price deserves attention. A shallow market’s price can be one order. Every later step is discounted by this one.

Fourth, how far. Measure the move against something. For an index perp out of hours, that is its own price at the last cash close. Compare it with a normal day’s range for that market. A move well inside the usual range is not news.

Then the lean

Fifth, who pays. Read funding. If it sits at the same rate as most other markets, it is at rest and says nothing. If it is well above or below, one side is paying to stay, as the resting rate sets out.

Sixth, who is leaning now. Read the premium, the mark against the oracle. It shows the pressure at this moment, ahead of funding. Reading the premium covers its limits.

Then the change and the neighbors

Seventh, what changed. Compare open interest with its earlier level and set that against price. Rising open interest into a move is new positions. Falling open interest is positions closing. This step needs a recorded history, since the venue does not serve one for open interest.

Eighth, what agrees. A single market is one witness. Check the other index perp, the mega-cap perps and, when they are open, index futures. Agreement across several markets is worth more than a large move in one.

What the checklist will not give you

It will not tell you where the stock trades at the next cash session. A perp’s price is a market price on another venue. It also covers only what has a perp. No liquid perp exists on the Russell 2000 or IWM, so small caps are outside it.

It is also only as good as the freshness of each number. A stale figure read with care is still stale.

Where to run it

The Stocks On-Chain tab of the Crypto Market Map puts mark, 24-hour change, funding, open interest and its change, volume and premium on one row per perp. Dr. NoVo, the Financial Markets Super Intelligence, reads the same fields, and you can put the question to him in plain English through the MCP & API.
