# Screen for premium

Trigger on: "where can I sell premium", "which names have rich options",
"cheap options to buy", "highest IV rank tonight", "iron condor candidates".

1. Call `scan_ranking` with `sort` set to `ivRankHigh` for selling premium,
   or `ivRankLow` for buying it. Use a limit of 25, or csv with a larger
   limit when the user wants to filter further.
2. For each name, state these facts exactly as returned:
   - **IV rank**, 0 to 100 against the name's own record. 50 or more reads
     rich, under 50 cheap.
   - **Implied vs realized.** Give `atmIv` beside `realizedVol`. IV above
     realized means options price more movement than the shares have shown.
   - **Expected move vs Typical move.** The expected move is one standard
     deviation to its expiry, from option prices. The Typical move is the
     average 20 trading day move, either way, for past stocks with the
     name's realized volatility. They agree when the expected move is about
     1.25 times the Typical move.
   - **Vol outlook and pullback chance.** The volatility outlook is the
     second model's. A falling outlook works for a seller, a rising one
     against. The pullback chance is how often past stocks with the name's
     realized volatility fell 6 percent or more from a peak within 20
     trading days. It is the risk a put seller carries. Never call the
     Typical move or the pullback chance the model's figures.
   - **The state.** Its `stateLabel`, such as Bullish, Low RV or Neutral,
     with the win rate quoted alone.
3. For the strategy the desk prints on a name, call `get_todays_book`. Trade
   Cards prints it. Quote it; do not invent one.
4. Never call an option overpriced, a trade good, or a name a buy. State
   the figures in the desk's words and let the reader decide.
5. Close with the stamp's trading day and the paper line, verbatim.
