Pre Trade Risk Checks Interview Guide
Pre-trade risk checks interview guide for order validation, price bands, size limits, exposure, throttles, rejects, and safe submission.
Candidates explaining risk controls in order gateways and trading systems.
Risk checks guard order entry
Pre-trade checks evaluate an order before it leaves the system. Common toy checks include price reasonableness, max size, exposure, duplicate order detection, and throttles.
Checks need clear failure behavior
A rejected order should produce an explicit reason and leave state consistent. Silent drops can create confusion for strategy logic and operators.
Concrete example
If a buy order price is far above a reference price, a price-band check can reject it before submission and alert the strategy or operator.
Risk controls have tradeoffs
Checks that are too strict can block valid trading, while loose checks can allow dangerous orders. Good answers discuss configuration, monitoring, and testing.
Common mistakes
Candidates often describe risk checks as a single if statement. Production-like reasoning includes state, limits, failure modes, logs, and escalation paths.
