Create TWAP Order

POST /api/v1/orders/twap/create

A TWAP order splits amount into smaller market orders, called sub-orders, and sends them over duration_in_seconds. Each sub-order uses slippage_percent as its maximum slippage. This endpoint creates a TWAP order that the matching engine runs. It has no price limit and no randomized slices. For those settings, create a TWAP order strategy instead.

How a TWAP order runs

Pacifica plans one sub-order for every 30 seconds of duration_in_seconds, plus one. It plans fewer if amount holds fewer lots than that, so each sub-order is at least one lot.
Pacifica sends one sub-order about every 30 seconds.
Each sub-order is the remaining amount divided by the remaining sub-order count, rounded down to the lot size. It is at most 3 times the planned sub-order amount.
The order ends as completed when the full amount fills.
The order ends as expired if part of the amount is still unfilled after the last planned sub-order, or when its time runs out. Its expiration is 30 seconds after the end of duration_in_seconds.
If the engine rejects a sub-order, the order stops and ends as rejected_due_to_sub_order.
You can have up to 4 open TWAP orders per account in each market.
