Earnings and expected move API, GET /batch/expected-move
How much is the market pricing each of these names to move by the next expiration?
Straddle-implied expected move for up to 25 symbols in a single request. Returns the expected move payload of the single endpoint for each symbol in tickers, keyed by symbol under results: the expiration used, days to expiry, spot, the move in dollars and in percent, and the implied range. Without expiration each symbol uses its own nearest expiration after today, so the horizons can differ across a mixed list; pass expiration to line them up. A symbol with no two-sided ATM straddle lands in errors and never fails the others. One rate-limit unit per call; the monthly allowance is spent per symbol.
The answer, in one call
Units first,
then the request.
expected_move_dollars in the underlying's price; expected_move_percent in percentage points (1.91 means 1.91 percent).
Per symbol, identical to /expected-move/{ticker}: the at-the-money straddle mid price for the expiration, taken as one standard deviation, against the live spot rather than the expiration's forward.

Parameters
Bounded,
and the bounds are stated.
Out-of-range numbers are clamped to the documented range, never silently changed to something else. A missing required field returns 400 with the reason.
| Name | In | Default | Range | Meaning |
|---|---|---|---|---|
tickers required | query | 1 to 25 symbols, comma-separated | The underlyings, upper case, duplicates dropped. A symbol with no listed options answers 404 for the whole call and names the symbol. | |
expiration | query | each symbol's nearest expiration after today | YYYY-MM-DD | One expiration for every symbol, so the moves share a horizon. |
