TWS stop versus stop-limit: why an exit may wait

Quick answer

A stop and a stop-limit are different instructions. A stop-limit adds a limit-price condition after its trigger, so triggering does not guarantee execution. Inspect the exact order type, trigger method, and prices.

Step by step

1 Open the exit order and identify whether it is STP or STP LMT.
2 Read the stop trigger price and, for stop-limit, the separate limit price.
3 Check the supported trigger method and session for the contract.
4 Compare the market movement with both the trigger and execution conditions.
5 Review the current order and position before replacing an exit.

A practical example

Suppose a sell stop-limit has a stop of 100 and a limit of 99. Once its trigger rules are met, the limit still matters. A fast move below the permitted sale price can leave it unfilled. This is why the two price fields should not be read as a promised fill price. Check the current order state and remaining position before replacing the exit.

Unsent stop-limit draft with separate LMT and STP fields — Selecting STP LMT exposes separate limit and stop prices. This selection was only an unsent paper draft and was cleared after capture. No stop order was sent. Captured in TWS paper mode on 3 October 2026. Open the image for full size.

Unsent TWS order with unchecked bracket, profit-taker and stop-loss controls — The bracket checkboxes are unchecked. This capture shows input locations only; no bracket was enabled or order transmitted. Captured in TWS paper mode on 3 October 2026. Open the image for full size.

How to confirm the result You should know whether the order has triggered, whether it remains working, and what price condition still applies.

Mistake to avoid

Do not describe a stop-limit as a guaranteed exit at the stop price.

Common questions

Can price pass my stop without a fill?

Yes, depending on trigger rules and, for stop-limit, its limit condition.

Is the chart’s last price always the trigger input?

No. Check the contract’s set and supported trigger method.
