# market_price_moved

> Sends a sports or esports market's line move: the before and after prices over your window, the spread, the book depth, the game state and the large trades behind it.

Subscribe with `price_move_filters` on [create](https://docs.0xinsider.com/api-reference/endpoint/create-webhook.md) or update: `min_move_cents` (2 to 50) and `window_seconds` (60, 120, 300 or 900) are required. Each subscription gets at most one delivery per market per window, unless the move grows further in the same direction. Pro and Max only.

Add `min_book_usd_within_2c` to receive only moves with at least that many dollars resting within 2 cents of the price on each side. A move whose depth we could not measure carries `book_depth_within_2c: null` with a reason, and that filter skips it.

`phase` says where the game stood when the price moved. It is `pre_game` before the scheduled start (the `scheduled_at` the games endpoints serve) and `in_play` once the game is live. It is `unknown` otherwise: the market has no scheduled start, the start passed before the game went live, or we could not read the game state.

The [OpenAPI spec](https://docs.0xinsider.com/api-reference/openapi.json) carries an example delivery, `nba_moneyline_before_tip`, that you can sign and post to your own server to test it. The [Discord line-move alerts](https://docs.0xinsider.com/recipes/discord-line-moves.md) recipe does that end to end. The [Webhooks guide](https://docs.0xinsider.com/guides/webhooks.md) covers signatures, retries, and replay.
