# Modify a pending perp trigger order

> Modify an existing pending trigger order (limit / TP / SL) by rewriting
the partial-close size and/or trigger price on its `position_request`
PDA via `updateDecreasePositionRequest2`.

Both `size_usd_delta_e6` and `trigger_price_e6` are required on the
wire — the on-chain ix overwrites unconditionally — so callers must
pass the previous value through for whichever field they aren't
changing.

Idempotent on `client_order_id` (60s window).
