Which platform is best for automated and algorithmic trading?
Verdict
- Pepperstone is our pick for automated and algorithmic trading in the UK because one FCA-regulated account supports three routes: cTrader Automate (C# cBots), MetaTrader 4 and 5 expert advisors, and API trading.
- Eligible and professional clients get a free VPS, and Pepperstone reports execution from 50 milliseconds with a 99.32% fill rate (its own January–March 2026 data).
- The best platform depends on your code: C# fits cTrader, existing EAs fit MetaTrader, and custom systems fit an API.
- Capital.com allows expert advisors on MT4 and MT5 and offers guaranteed stops, which Pepperstone does not.
The 'best' algorithmic platform is the one that runs your strategy reliably at a broker that executes it well. Pepperstone supports three automation routes on one UK account, which is why it is our pick. Below we match each route to the type of trader, and list the checks that stop a working backtest from failing live.
Three automation routes at Pepperstone
Pepperstone Limited (FCA 684312) supports automation on cTrader through cTrader Automate, where strategies called cBots are written in C#; on MT4 and MT5 through expert advisors; and through API trading for custom systems. A free VPS is available to eligible and professional clients. All of this runs on UK accounts with negative balance protection for retail clients and FSCS cover for eligible clients up to £85,000.

Which route suits which trader
| Route | You write in | Best for | Razor FX commission (USD account) |
|---|---|---|---|
| cTrader Automate | C# | Developers starting new strategies | $3.00 per side |
| MT5 expert advisors | MetaTrader's language | Traders with MT5 EAs; available on every UK account | $3.50 per side |
| MT4 expert advisors | MetaTrader's language | Legacy EAs; Razor and spread betting only | $7 per lot on opening |
| API trading | Your own stack | Custom or multi-broker systems | Depends on account |
Checks before running a strategy live
- Recode position sizing for UK retail caps: 1:30 on major FX, 1:20 on major indices and gold, 1:10 on other commodities, 1:5 on shares.
- Model commission correctly: Razor's MT4 charge lands on opening, while cTrader and MT5 charge per side.
- Allow for slippage. Pepperstone's UK terms say stop-loss orders can't be guaranteed to fill at the requested level.
- Account for overnight fees if your system holds positions past 10 pm UK time.
- Run the strategy small first; Pepperstone's £10 card minimum makes a low-risk live test possible.
Other UK brokers for automated trading
Capital.com (FCA 793714) permits expert advisors on MT4 and MT5, allows hedging, and offers guaranteed stop-loss orders — useful for a system that must cap its worst loss. It does not offer cTrader. IG lists APIs alongside MT4, MT5 and ProRealTime, and Saxo publishes an OpenAPI. Our verified data includes no execution statistics for these brokers, so compare live fills on a small account before scaling.
