🎯 War Rooms — a whole index on one screen

Every other page reads one ticker, or every ticker as a list. A War Room shows one group of stocks together — the Nasdaq-100, the Dow 30, or our own forty AI stocks: who is moving, how broad the move is, which names stopped moving with the rest, and where option dealers stand. The rooms are open to everyone.

💡 Two questions, one screen What is the field doing? — the headline, the bar of ups and downs, the map. Who is doing it? — the movers, the stocks that lift or weigh on the group, the table. Read the first before the second: a stock up 2% means one thing on a day when four in five are up, and another when it is alone.

Live, or the close? — the line under the title

The page is rebuilt every night from end-of-day data. While the US market is open it also lays delayed quotes over that, about once a minute. The line under the title always says which you are looking at.

The line says	What the figures are
● Market open	Delayed quotes, up to 15–20 minutes behind, refreshed about once a minute. The headline, the six figures, the map, the movers and the table follow the quotes.
Closed — today's date	The day's closing prices from the delayed quotes. The full rebuild (breadth charts, correlation, option readings) runs later that night.
At the close of …	Everything is from that close: our own end-of-day data.

⚠ Two clocks on one pagePrices move with the session. The option readings (dealer gamma, IV rank, walls) and the correlation study do not: they are always from the last close, because they are computed from end-of-day option chains and daily closes.

The headline and the bar

The green-and-red bar counts stocks: how many are up, how many are down. The headline above it is chosen from two things — the group's move weighted the room's own way, and the share of stocks that are up.

Headline	When the page writes it
A broad advance	The group is up and 75% or more of the stocks that moved are up.
More stocks up than down	The group is up and 55% to 75% are up.
Up — carried by a few heavy names	The group is up although fewer than 55% of its stocks are. The weight is doing the work.
A broad decline	The group is down and 25% or fewer are up.
More stocks down than up	The group is down and 25% to 45% are up.
Down — pulled by a few heavy names	The group is down although more than 45% of its stocks are up.
A split field, and little net movement	The group moved less than 0.1% and between 40% and 60% of the stocks are up.

How each room is weighted. The Dow 30 by share price, exactly as the index is: a $600 stock counts six times a $100 stock. The Nasdaq-100 by its index weights, read from the daily holdings of a fund that tracks it — not by plain company size, because the index holds its very largest names down. The AI room by market value (it is our own list, not an index).

The six figures

Figure	How to read it
The index (or its fund)	During the session: the index itself, with its level. On the close: the fund that tracks it (QQQ, DIA).
The stocks, weighted	The room's own stocks added up the room's way, and under it the average stock. A gap between the two is the heavy names pulling one way and the rest another.
Up / down	The count of stocks, not weighted.
Above their 50-day average	The share of stocks whose price is above their own 50-day average (and, smaller, the 200-day).
20-day highs / lows	Stocks at their highest or lowest close of the last 20 sessions; under it, 52-week highs and lows.
Moved more than their options priced	See option dealers below.

The heat map

One tile per stock, grouped by sector (by camp in the AI room). Size is the stock's weight in the room; colour is its change. Hover a tile for its figures, click it for the stock's card.

Button	What it does
Colour: Today · 5 days · 1 month · This year	The period the colour shows. A tile reaches full colour at ±3% for today, ±6% for five days, ±12% for a month and ±40% for the year; anything beyond looks the same.
Size: weight · Equal	Weight shows what moves the index. Equal draws every stock the same size, so the small names can be read — the default on a phone.
◐ Blue / orange	Blue for up and orange for down instead of green and red — easier to tell apart with red-green colour blindness. Your browser remembers the choice.

🧭 Try thisSwitch the size between weight and Equal on a day the headline says "carried by a few heavy names". In the weight view the map looks green; in the Equal view most of it is red. That difference is the whole story of the day.

Movers — two different lists

List	How to read it
Biggest gains · Biggest losses	The largest changes of the day, in percent, whatever the stock's weight.
Lifting the group · Weighing on it	Change × weight: how many percentage points of the group's move come from that one stock. The figures of every stock add up to the group's move.

Below, By sector shows each group's own weighted move as a bar from the middle, how many of its stocks are up, and its weight in the room.

Breadth — is the move broad?

Chart	What it tells you
Weighted against every stock equal	One year, both started at 100. The weighted line above the equal one: the heavy names carried the year. Below: the smaller names did better.
Stocks above their 50-day average	The share of the room's stocks above their own 50-day average, day by day, with today's value beside a typical session of the year.

Who broke ranks — the correlation shift

Stocks of one group usually move together. For every pair of stocks in the room the page compares two windows that do not overlap: the last 63 sessions (about three months) and the 252 sessions before them (a year). Correlation runs from −1 (opposite) through 0 (no link) to +1 (together).

Reading	Change in the pair's correlation
Shifted	fell by more than 0.20 — the two moved together clearly less than before
Minor shift	fell by 0.05 to 0.20
Negligible	fell by less than 0.05
Steady	unchanged, or rose by less than 0.30
Strengthened	rose by 0.30 or more

Part	How to read it
How tightly the group moves as one	The average correlation of all pairs over a rolling 63 sessions. High: everything moves together (usually a market driven by one big worry or one big hope). Low: each stock on its own story.
Left the pack · Joined the pack	Each stock's average correlation with all the others, year before → last three months.
Every pair at a glance	A square per pair. Blue: together. Orange: apart. Change shows the shift; the other two buttons show each window by itself. Hover a square, click it for the pair.
Moved apart / together the most	The twelve largest changes each way. Click a row for the pair: the two prices over both windows, and their correlation as it moved.
lowest (highest) of 5 quarters	The last three months are below (above) every one of the four quarters before.
mostly one session	Taking one single day out changes the three-month correlation by 0.15 or more. It is usually a company report on which the two went far apart.

⚠ A shift is where to look, not proofWith 63 sessions a single pair's correlation is uncertain by about ±0.1. Among thousands of pairs some large changes appear by chance alone. And one report day can make three months of "broken" correlation by itself — the page marks those pairs, and the pair's chart shows it as a cliff instead of a drift.

Where option dealers stand

This is the site's own subject, added up over the room. All of it is from the last close.

Figure	How to read it
Long gamma / short gamma	How many stocks have dealers on each side. Long gamma: their hedging leans against a move and tends to calm it. Short gamma: it goes with the move and can let it stretch.
Median IV rank	The typical stock's implied volatility in its own one-year range: 0 the cheapest day, 100 the dearest.
IV rank 80 or more / 20 or less	How many stocks sit at the dear and at the cheap end.
Closed through an option wall	Stocks that closed above their call wall or below their put wall at the last close.
Within 1.5% of a wall	Stocks whose close was that near to a call wall or a put wall.
Moving more than their options priced	The day's change divided by the one-day move the options price (implied volatility ÷ √252). 1.0× = exactly the priced move; 2× = twice it.

Members also get At the walls: the price on view — live during the session — against last night's call wall and put wall, stock by stock. "through" = the price is beyond the wall; "near" = within 1.5% of it.

🎓 Pro tipRead the correlation line and the option figures together. A falling "how tightly the group moves" with a calm index means the single stocks are doing the moving: the index's options price less movement than the average member's do, which is the backdrop a dispersion trader looks for. The opposite — the line rising fast — is a market trading as one block, where a hedge with the index covers more of each stock's risk than usual. And a stock that has moved more than its options priced while its dealers are short gamma is in the one setting where hedging adds to the move instead of absorbing it.
