Direct answer: how long do forex trades last?
In forex, “how long a trade lasts” does not have one universal answer. It depends on what you mean by “last”:
- Holding time: how long you keep a position open (can be seconds, minutes, days, or longer).
- Execution time: how long it takes for your order to be matched and for a quote to result in an accepted deal (often very short, typically within the same general time window as trading activity).
- Last Look processing time: some venues or providers use a Last Look step, where they may briefly decide whether to accept or reject an incoming order after receiving it. That decision window is usually short, but the exact duration is provider- and condition-dependent.
So, if you are asking about trade duration as a concept, the safest bounded answer is: the position lasts for the period you hold it, while the Last Look decision (if used) is a short intermediate step in the execution process.
How “trade duration” works in practice
To make this precise, separate three time concepts:
-
Order-to-execution timing When you submit an order, the relevant “trade start” moment is when the execution becomes an accepted transaction (not merely when you sent an intent). The time between submission and acceptance varies with how the venue routes orders and how quickly it evaluates price conditions.
-
Last Look in forex Last Look is the idea that, after an order is presented, the venue/provider may perform a final check before confirming. During that check, the incoming order may be accepted or rejected. The key point for your timing question is that Last Look adds an additional micro-window inside execution, rather than defining how long you can hold the position.
-
Position holding time Once a trade is accepted, the “lasting” part becomes the time you keep the exposure open. That duration is not inherently fixed by Last Look; it is determined by your chosen lifecycle for the position (for example, closing it later), plus the contract’s operational terms.
Example and checks you can use
Because “duration” can be ambiguous, you can check which of these timelines you actually care about:
- If you mean “How long until my order is confirmed or rejected?”, you are asking about execution/Last Look timing, which is typically brief but not identical across providers.
- If you mean “How long can I keep the currency exposure?”, you are asking about holding time, which can extend far beyond any Last Look decision.
- If you see executions that appear to arrive with occasional rejects or cancellations, that behavior can be consistent with a Last Look mechanism—however, the exact reason and timing depend on the provider and current conditions.
To verify timing in a concrete way, look for the terms your provider publishes about execution handling (including any mention of Last Look behavior) and compare how your executions behave under similar market conditions.
Limitations and uncertainty
This answer is intentionally bounded:
- No single duration applies to all forex trades because “lasts” can mean different steps (holding vs execution vs Last Look processing).
- Without provider-specific documentation, you cannot infer the exact Last Look window length.
- Market conditions and routing can change execution behavior, so you should expect timing variability.
If you need an exact number for a specific setup, the only reliable path is to use the execution terms and operational behavior of the particular provider/venue involved, not a generic rule.
