## Rejection Criteria

Rejection criteria in financial derivatives and cryptocurrency trading refers to the specific quantitative or qualitative thresholds that must be met for a trade, protocol interaction, or risk management action to be accepted by a system. These criteria act as a gatekeeping mechanism to prevent invalid, risky, or unauthorized transactions from entering the order book or executing on-chain.

In the context of automated trading systems, these criteria often filter out orders that violate margin requirements, price deviation limits, or account balance constraints. For decentralized protocols, rejection criteria may be embedded in smart contracts to prevent interactions that do not meet gas requirements, signature verification, or specific governance states.

By enforcing these rules, markets maintain integrity and prevent systemic failure caused by erroneous inputs. Traders must understand these criteria to ensure their strategies execute successfully within the bounds of exchange or protocol rules.

Failure to meet these criteria typically results in immediate transaction rejection or order cancellation.
