Which forex brokers offer the most stable execution?
Verdict
- No broker publishes execution data in a comparable form, so 'most stable' can't be ranked on evidence; Pepperstone, our pick, is the only broker in our data that publishes execution statistics: 'from 50 milliseconds, with a 99.32% fill rate and no dealer intervention', for trades from 1 January to 31 March 2026.
- Those are Pepperstone's own figures, not our tests.
- Stable execution also depends on your setup: platform, server location (Pepperstone offers a free VPS to eligible and Pro clients) and the order types you use.
- Capital.com, our second choice in Australia, offers guaranteed stop-loss orders, which fix your exit price; Pepperstone does not.
Stability means fills that arrive quickly, at or near the price you asked for, even when markets move fast. Very few brokers publish anything you can measure that against. Here is what is published and how to test the rest yourself.
Pepperstone publishes execution numbers; the others in our data don't
Pepperstone states fills from 50 milliseconds with a 99.32% fill rate and no dealer intervention, measured on its trades in the first quarter of 2026. That gives you something specific to hold it to, which is more than the other brokers in our fact files offer. Australians trade with Pepperstone Group Limited (AFSL 414530), on Razor pricing averaged at 0.1 pips on EUR/USD.

What stable execution should mean
- Fill rate: the share of orders filled rather than rejected.
- Speed: time from order to fill, ideally as an average rather than a best case.
- Slippage: how far fills land from the requested price, and whether it runs both ways.
- Behaviour around news and the daily rollover, when spreads widen.
Reading Pepperstone's claim carefully
- 'From 50 milliseconds' is a best case, not an average.
- The 99.32% fill rate covers one quarter's trades.
- No slippage breakdown is published, so you can't see how often fills were better or worse than requested.
- We have not tested it ourselves; treat it as Pepperstone's statement.
Making your own execution steadier
- Run EAs or cBots on a VPS close to the broker's servers; Pepperstone offers one free to eligible and Pro clients.
- Use limit orders where the strategy allows, so you never pay more than your price.
- Avoid opening positions in the minutes around the daily rollover and major data releases.
- Log your own fills for a month and compare requested and filled prices.

Does Pepperstone requote orders?
Pepperstone says there is no dealer intervention; it does not publish a separate requote statistic.
Can a stop-loss slip at Pepperstone?
Yes. Pepperstone offers no guaranteed stop-loss in Australia, so in a fast or gapping market a stop can fill beyond its level.
Which Pepperstone platform suits execution-sensitive trading?
cTrader has the lowest Razor FX commission (USD 3.00 per side) and runs cBots; MT5 suits EA traders. Either works with the free VPS for eligible clients.
CFDs, including perpetual CFDs, are complex and leveraged, and you can lose money rapidly. Only trade with money you can afford to lose and only once you understand the product. This is not investment advice; read Pepperstone's Product Disclosure Statement and Target Market Determination first.
