When a Copy From the Feed Does Not Fill

What happens between pressing copy and an order filling, and what each failure means when a copy from the feed does not go through.

Last updated August 24, 2026

What Happens During Execution

After you confirm, Polycopy converts the copy request into a Polymarket CLOB order with price protection and status tracking.

Validation and balance checks

Polycopy validates the request, checks pUSD Cash and allowance, verifies the market can accept orders, and confirms the requested size fits market rules.

Rounding and signing

The order is rounded to the market tick and size rules, then signed through the connected wallet setup before submission.

Submission to Polymarket CLOB

Polycopy submits the signed order to the Polymarket central limit order book, then polls order status so the app can show whether it filled, rested, or failed.

Possible statuses

You may see pending, open, filled, partial, expired, canceled, rejected, or timed out. Partial means only part of the requested amount filled; open means a resting Limit/GTD order can still fill before expiry.

If A Trade Fails

A failed copy usually means the market, wallet, or exchange rejected the order conditions. The useful response is to identify which condition changed and decide whether the trade still deserves another attempt.

Common market reasons

Price moved beyond your tolerance, liquidity was too thin, your amount was too large for the available book, the order was below minimum size, or the market closed or resolved.

Common wallet reasons

Your pUSD Cash may be too low, funds may be tied up in open positions or open orders, allowance may need refreshing, or the wrong wallet may be connected.

Common system reasons

Rate limits, exchange errors, proxy issues, temporary network failures, or delayed order-status responses can cause rejected or timed-out attempts.

What to try first

Refresh the card price, reduce the amount, check that the market is still open, and compare pUSD Cash with portfolio value. Cash available for new orders is what matters.

Adjust execution carefully

A wider slippage tolerance or a Limit/GTD order can improve fill chance, but only use wider tolerance when you are still willing to own the trade at that protected price.

Check your records

Open Orders and Portfolio before retrying. A partial fill or resting order can already exist even if the first attempt looked uncertain.
