# Follow a liquidity provider

`POST https://api.getchord.xyz/v1/lp/watch/follow`

Source: https://getchord.xyz/docs/api-reference/operations/lpwatchfollow/

Alerts for `wallet` when `target` opens or closes a position, from now on (a follow does not replay the wallet's past). An "opened" alert links to the same pool with the same range; nothing is copied for the wallet. At most 10 followed wallets.
