Stop-Limit Order
Pronunciation: STOP-LIM-it OR-der
Also known as: Stop Limit Order
Definition
Stop-Limit Order is an order that becomes a limit order when a specified stop price is reached or triggered. The stop controls activation and the limit controls acceptable execution price, so the order may remain unfilled after triggering. In production, teams should define the authoritative record, identifiers, ownership, lifecycle rules, and evidence used to confirm the outcome. They should also reconstruct every order from submission through amendment, fill, cancellation, and final position without relying on one venue status.
Overview
Stop-Limit Order is an order that becomes a limit order when a specified stop price is reached or triggered. The stop controls activation and the limit controls acceptable execution price, so the order may remain unfilled after triggering.
Stop-Limit Order is closely connected to Limit Order, Market Price, and Slippage Tolerance. These concepts can appear in the same workflow, but they represent different records, decisions, controls, or stages.
Stop-Limit Order can appear in the same workflow as Limit Order, Market Price and Slippage Tolerance, but the records should remain separately identifiable. A relationship between them does not prove that pricing, execution, settlement, custody, or accounting has completed.
For Stop-Limit Order, the central operating question is whether the stated result can be reproduced from the underlying evidence. In this case, the stop controls activation and the limit controls acceptable execution price, so the order may remain unfilled after triggering. That evidence should remain available after corrections, later settlements, or revised market data arrive.
Teams applying Stop-Limit Order should retain instrument, side, quantity, order conditions, venue, timestamps, fills, cancellations, and final status. A further point from the source definition is that in production, teams should define the authoritative record, identifiers, ownership, lifecycle rules, and evidence used to confirm the outcome. These fields help distinguish an expected timing difference from a real pricing, execution, liquidity, or settlement break. This added control specifically concerns an order that becomes a limit order when a specified stop price is reached or triggered.
The main control tests should cover stale market data, incorrect triggers, duplicate submission, price gaps, partial fills, venue rejection, and inconsistent cancellation. Both normal and stressed scenarios matter because an apparently available price, balance, venue, or settlement route may fail when the transaction is actually attempted. The record-level focus here is an order that becomes a limit order when a specified stop price is reached or triggered.
Key Takeaway
Stop-Limit Order should be managed with explicit scope, authoritative evidence, accountable ownership, controlled exceptions, and measurable production safeguards.
