๐ŸŒ™ Tonight โ€” only what changed

The Scanner shows states ("this ticker is short gamma"). Tonight shows changes ("this ticker became short gamma tonight"). Six short lists, each one a kind of change since the session before โ€” nothing else.

๐Ÿ’ก Why changes, not states A state can hold for weeks and is old news. A change is the thing that is new. The page is deliberately strict: a reading going "unusual" fired on most tickers every night, so only six kinds of change are listed โ€” each with a threshold that keeps the lists short.

In 30 seconds

  1. Look at the row of numbers under the title: each is a list and how many tickers are on it tonight. Click one to jump to it.
  2. In a list, read the sentence in What changed โ€” it says exactly what happened.
  3. Click a ticker for its card, or star it (โ˜†) to follow it.

Closed through a wallThe close finished beyond the previous session's call wall or put wall. The wall is then drawn again from the new price.the size of the day's move

A wall movedThe biggest strike is a different one tonight, after standing at least five sessions and without the price closing through it: positions were opened somewhere else, or closed here. Only walls within 15 % of the price are listed.how long the old wall had stood

Each row: the ticker, a sentence of what changed, the close, 1-day change, gamma, IV rank and the move grade.

The most unusual books tonight

Not a change but a state: the tickers with the most readings beyond 3ฯƒ of their own last 60 sessions and rare for their own year โ€” the same readings the Viewer marks "unusual". Only busy option markets (A and B) are listed, because a thin one swings by itself.

โš  A change is a fact about tonight"Dealers turned short gamma" says how hedging now works โ€” more movement either way โ€” not which way the price goes. A closed-through wall is a description of the day, not a signal.

Alerts โ€” being told

A member does not have to open this page to know. The same changes, on the tickers of your โ˜… list, show as a number beside Alerts in the top menu โ€” and, if you switch it on in your account, arrive by e-mail after the data updates: one message, only when something on your list changed.

In your account you also choose what you are told about (walls, dealers changing side, implied volatility, volume, the move grade) and keep the list itself. Every e-mail carries a link that stops them. A change is sent once โ€” the night it happens.

A routine that works

  1. Open Tonight after the nightly update.
  2. Tick โ˜… My list: anything on your names?
  3. Then every ticker: skim "Closed through a wall" and "Dealers changed side".
  4. Click the interesting ones; open them in the Options Chart.
