Which broker is best for day trading indices?
Verdict
- Pepperstone is our pick for day trading indices in the UK: published spread bet minimums of 0.4 points on the US500 and 0.9 on the GER40, no commission, and no overnight fee if you close before 10 pm UK time.
- For an intraday trader the spread is the main cost: ten round trips a day at £1 a point on the US500 cost about £4 at the published minimum.
- Pepperstone states fills from 50 milliseconds with no dealer intervention; it has no guaranteed stop, which matters less for traders who close the same day.
Day traders open and close index positions many times a day, so small differences in spread decide the result, and overnight financing barely matters. That makes the per-point spread, execution and platform the three things to compare. Pepperstone publishes all three for UK clients, and here is what a trading day costs on each main index.
Why Pepperstone suits index day traders
Pepperstone's spread bets carry no commission and its published minimums are among the tightest it offers on any account. Positions closed before 10 pm UK time avoid the overnight fee entirely. It states execution from 50 milliseconds with a 99.32% fill rate (fills from January to March 2026), and day traders can use cTrader, TradingView, MT4, MT5 or its own platform. Pepperstone Limited is authorised by the FCA (684312).

The cost of a day's index trading
Ten round trips a day at £1 a point, at Pepperstone's published spread bet minimums. Real spreads widen around the open and news, so treat these as a floor.
| Index | Minimum spread (points) | Cost per round trip | Cost per day |
|---|---|---|---|
| US500 | 0.4 | £0.40 | £4 |
| GER40 | 0.9 | £0.90 | £9 |
| NAS100 | 1 | £1 | £10 |
| UK100 | 1 | £1 | £10 |
| JPN225 | 7 | £7 | £70 |
Tools that suit intraday index traders
- TradingView, available on Pepperstone's spread betting and Razor accounts, for chart-based order entry.
- cTrader, with C# automation through cTrader Automate.
- MT4/MT5 with Pepperstone's Smart Trader Tools, such as Trade Terminal and Correlation Matrix.
- Pepperstone's own app for managing positions away from the desk.
Intraday risk controls
- Retail margin on major indices is 5% (1:20), so a £5-a-point UK100 position at a hypothetical 8,000 ties up £2,000.
- Set a daily loss limit before the session and stop when you hit it.
- Stops can slip at Pepperstone; avoid holding through data releases if a few points of slippage would hurt.
- Professional status (up to 1:500 on indices) requires 10 significantly sized trades per quarter as one of three tests, but removes negative balance protection.

Which index is cheapest to day trade at Pepperstone?
The US500, with a published spread bet minimum of 0.4 points.
Do day traders pay overnight fees?
Not if every spread bet is closed before 10 pm UK time, when Pepperstone's overnight fee applies.
Is spread betting or CFD better for day trading indices?
At Pepperstone the spread bet minimum matches Razor's on main indices, carries no commission and, per Pepperstone, is exempt from CGT, so most UK day traders choose the spread bet.
Day trading leveraged index products is high risk; frequent trading can multiply losses as well as costs. Pepperstone discloses that 73.6% of its UK retail investor accounts lose money on spread bets and CFDs. Not investment advice.
