Order Types
Specifications for limit and market-style orders on the CLOB.
Doji supports the full range of Polymarket CLOB order types. Selecting the right type is essential for managing your execution risk and cost.
Supported Types
GTC (Good-Til-Cancelled)
The standard limit order. It remains on the orderbook until it is fully filled by a counterparty or manually cancelled by you.
- Use case: When you have a specific target entry or exit price and are willing to wait for a match.
FOK (Fill-Or-Kill)
An "all-or-nothing" order. It must be filled in its entirety immediately at your limit price. If a complete fill isn't available, the entire order is cancelled.
- Use case: When you need a specific size for a strategy and don't want partial exposure.
FAK (Fill-And-Kill)
A market-style limit order. It fills as much as possible at the current price, then cancels any remaining, unfilled portion.
- Use case: When you want to enter a position quickly and are okay with receiving less than your requested total size.
