IC Markets, Pepperstone, and FP Markets are the three ECN names that come up in every “best broker for EA” conversation, and for good reason: all three offer raw spreads, all three allow EAs without strategy restrictions, and all three are Australian-rooted with tier-1 regulation. The differences are narrower than the marketing suggests, but they are real, and they decide which one fits you.
Why these three
They share the same DNA: raw ECN pricing, MT4/MT5 plus cTrader, EA-friendly terms, and co-located servers. What separates them is spread consistency under stress, the commission structure, the regulatory entities you actually get, and where their servers sit relative to you.
Spread and commission comparison
| IC Markets | Pepperstone | FP Markets | |
|---|---|---|---|
| Raw spread (EURUSD) | 0.0 pips | 0.0 pips | 0.0 pips |
| Commission (MT round turn) | $7.00 | $7.00 | $6.00 |
| cTrader commission | $6.00 | $6.00 | n/a |
| Standard account | 0.8 pips | 1.0 pips | 1.0 pips |
All three advertise “from 0.0”, which tells you nothing. The commission is the difference: FP Markets is a dollar cheaper per round turn than the other two, which adds up for a volume-heavy EA. But the spread you actually get, not the advertised floor, is what matters, and that varies by hour and by symbol.
Execution and slippage
This is where the three separate, and it is the part no comparison table captures:
- IC Markets co-locates in Equinix NY4, runs a genuine ECN/STP feed, and is the default for latency-sensitive EAs. It has historically had the tightest and most consistent raw spreads of the three.
- Pepperstone is the regulation leader (ASIC, FCA, CySEC, DFSA) and has excellent execution, marginally behind IC Markets on raw spread consistency in my logging but ahead on regulatory comfort.
- FP Markets is the broadest multi-asset shop (500+ instruments including stocks and IRESS) and slightly cheaper on commission, but its forex spread consistency is a tick behind the other two.
For a scalping or grid EA, I would put IC Markets first on execution, Pepperstone first on regulation, and FP Markets first on cost-plus-breadth.
Account types
All three offer a standard account and a raw/ECN account. For EAs, use raw. The standard account’s spread markup is paid on every trade your bot makes, which compounds fast. The one nuance is very small accounts: on micro lots, the $6-7 commission is proportionally large, and a tight standard account can win. I walk through that arithmetic in best broker for scalping EAs.
EA and VPS support
All three fully allow EAs with no strategy restrictions, which is the table stakes. The differences:
- IC Markets gives a free VPS at 15 lots a month, the lowest threshold of the three.
- Pepperstone offers a free VPS to pro clients and supports cBots on cTrader.
- FP Markets supports EAs on MT4/MT5 and offers a VPS, with the broadest instrument set for a diversified EA.
If you run one FX EA, the VPS and execution at IC Markets win. If you run a diversified portfolio across FX, indices, and stocks, FP Markets’ breadth matters.
Regulation
All three are ASIC-regulated at the Australian root, but the entity you get depends on your country:
- Pepperstone has the broadest tier-1 reach (ASIC, FCA, CySEC, DFSA), which means most clients land on a tier-1 entity.
- IC Markets serves most international clients through a Seychelles/Bahamas entity, which is the cost of its execution flexibility.
- FP Markets sits between them, with ASIC, CySEC, and FSCA plus offshore entities for some regions.
This is the real tradeoff: IC Markets gives you the best execution but often offshore regulation; Pepperstone gives you tier-1 regulation at a hair more spread. Which you prefer depends on how much you value regulatory protection versus raw execution.
Which to pick by strategy and region
- Latency-sensitive scalper or grid: IC Markets, for execution and the free VPS.
- Regulation-conscious trader anywhere: Pepperstone, for the broadest tier-1 coverage.
- Cost-focused multi-asset trader: FP Markets, for the cheaper commission and 500+ instruments.

Risk warning. A raw ECN account is a tool, not a guarantee. The tightest advertised spread means nothing if your EA is oversized or your strategy is untested. Backtest on the broker’s real feed and size for the worst case before funding.
