Lowest Spread for Scalping — Straight Answer
For scalping and high-frequency algo trading, the advertised "spreads from 0.0 pips" is not what decides — the effective all-in cost base: raw spread + commission is. Across our reviews, the genuine raw/ECN brokers deliver the lowest effective costs: IC Markets (~0.6–0.7 pips effective on EUR/USD), FP Trading, Fusion Markets, Axi (Pro account, not a partner) and RoboForex on its Prime account (the lowest per-side commission in this comparison); the exact commissions are listed in the overview below. Which broker is cheapest for your frequency depends on lot size and round turns — the table below contains every broker we tested that offers a raw/ECN account, our recommendations (partner brokers) first, then all others by score.
Why Only All-In Cost Matters for Scalpers
A scalping EA fires dozens of round turns a day depending on the system. At that frequency every hundredth of a pip eats performance. "Spreads from 0.0 pips" alone is therefore worthless — the second line of the pricing model (the commission) decides.
EUR/USD worked example: 0.0-pip raw spread + 7.00 USD round turn (3.50 USD/side) ≈ 0.7 pips effective on a standard lot. With a 0.1-pip raw spread and 6.00 USD round turn you also land at ~0.7 pips. The numbers sound identical and arithmetically they are, since both components scale with lot size. What changes the picture is trade frequency, not lot size: the more round turns your EA fires, the more the commission share dominates.
Hidden costs such as requotes, inflated swaps and concealed markups on the raw feed can neutralise any spread advantage. A nominally cheap broker with frequent requotes and 2-pip slippage is more expensive in practice than a nominally pricier broker with clean execution. That is why we always rate spread in the context of execution quality — a full breakdown lives in our spread comparison.
Raw/ECN vs. Standard Account for Scalping
Standard account (no commission): The broker builds its margin into the spread. Typical EUR/USD spreads run 0.8–1.6 pips. Almost always too expensive for scalping.
Raw/ECN account: The liquidity provider's raw spread passes through nearly unchanged, with a transparent commission charged separately — at the best brokers 2.00–3.50 USD/lot/side. Full cost transparency and predictable maths for EAs trading fixed lot sizes. The only sensible choice for scalping.
ECN tiering (Prime, PRO, Institutional): Some brokers offer cheaper tiers above certain volume or deposit thresholds. RoboForex charges 10 USD per 1M — round turn ≈ 2 USD per lot (Prime); lot = 100,000 USD notional on Prime and 20 USD per 1M USD volume per side — round turn ≈ 4 USD per lot (ECN) on ECN; Vantage offers a PRO ECN account at from 1.50 USD/lot/side (PRO ECN), minimum deposit 10,000 USD (PRO ECN); IC Markets has a global Raw Pro account at 1.50 USD/side from a 5,000 USD deposit. Traders moving large lot volumes regularly should ask specifically about such tiers.
The Cheapest Scalping/Algo Brokers at a Glance
IC Markets charges 3.50 USD/lot/side (MT, 7 USD round turn) · 3.00 USD/side (cTrader, 6 USD RT) for its Raw account. With a typical EUR/USD raw spread of 0.0–0.1 pips, all-in costs land at ~0.6–0.7 pips — top tier, plus servers in Equinix NY4 (MT4/MT5) · Equinix LD5 (cTrader) and unrestricted scalping. IC Markets review. The sister brand IC Trading charges the same commission but is licensed solely by the FSC Mauritius.
FP Trading offers 3.00 USD / 2.75 EUR / 2.25 GBP per lot per side (Raw, 6 USD round turn) on its Raw account — marginally below IC Markets on MetaTrader — at comparable spread quality. One of the most cost-efficient options once you account for offshore regulation. FP Trading review.
RoboForex stands out with its Prime account at 10 USD per 1M — round turn ≈ 2 USD per lot (Prime); lot = 100,000 USD notional — the lowest per-side commission in this comparison. For high-volume scalping EAs it can be arithmetically hard to beat. RoboForex review.
Fusion Markets comes in below IC Markets and FP Trading, though above RoboForex Prime, at 2.25 USD/lot/side (Zero, 4.50 USD round-turn) on its Zero account; its ASIC licence covers Australian clients only, everyone else is served via VFSC or FSA. Fusion Markets in detail.
Vantage PRO ECN charges from 1.50 USD/lot/side (PRO ECN), minimum deposit 10,000 USD (PRO ECN) — one of the cheapest offerings on the market. International clients, including those in the DACH region, are however served by its FSC Mauritius entity; ASIC and FCA only cover clients in Australia and the UK respectively. Full Vantage review.
Axi (not a partner) is also at 2.25 USD/lot/side (Pro, 4.50 USD round turn) on the Pro account, with tier-1 regulation including ASIC, FCA and CySEC. Axi review.
Pepperstone (not a partner) charges 3.50 USD/lot/side (Razor MT4/MT5/TradingView, 7 USD RT) on the Razor account, or 3.00 USD/side (cTrader, 6 USD RT), the same level as IC Markets, with broad tier-1 regulation. Pepperstone review.
Tickmill (not a partner) costs 3.00 USD/lot/side (Raw, 6 USD round-turn) on the Raw account with FCA and CySEC licences. Tickmill review.

Which Spread Type Suits Which EA Strategy?
- Scalping EAs (M1–M5, many round turns): raw/ECN essential; commission structure decides. Target: all-in costs below 0.7 pips on EUR/USD.
- Trend / swing EAs (H1–H4, few trades): a standard account can be cheaper at only 1–2 trades per week. Run the maths in backtesting.
- Grid / martingale EAs: every pip compounds exponentially — lowest commission is mandatory.
- News-based EAs: spread spikes at data releases hit the account hard; check for a markup on the raw feed and consider a news filter.
