# Create algo order

POST https://api.prod.paradex.trade/v1/algo/orders
Content-Type: application/json

Create a new algo order

### TWAP

TWAP orders break a large trade into smaller ones over time to reduce market impact:
- Sub-orders are placed every 30 seconds.
- Order duration is between 30 and 86,400 seconds, in multiples of 30.
- Supported sub order type: MARKET


Reference: https://docs.paradex.trade/api/prod/algos/create-order
