Order types — market, limit, TP, SL
How our order types map to Polymarket CLOB primitives, minimum-size rules, and the browser-side stop-loss.

Market (FOK) orders
Instant fill against the current best-of-book. Under the hood: FOK against Polymarket's CLOB. Polymarket enforces a $1 minimum notional; we ceil-size shares so tiny buys still land. E.g. $1 at 64¢ ask → 2 shares ($1.28), not 1 share ($0.64 rejected).
Limit (GTC) orders
Rests on the book at a specified cent price. Polymarket enforces a 5-share minimum per limit — we surface a friendly hint if you go under.
Take-profit (TP)
Placed as a GTC SELL at your specified cent price. Fires atomically on Polymarket's CLOB when the market crosses.
Stop-loss (SL)
Runs browser-side (Polymarket has no native stop-loss primitive). We monitor the ask; when it crosses your stop, we fire a market SELL. Requires the tab to be open and connected. For unattended SL, use Agents with a "market crossed X¢" trigger + SELL action.
Cancel + modify
Every open order has a Cancel button. Modify = cancel + replace (Polymarket's CLOB doesn't support in-place modify).
