Exness and IC Markets are two of the most-used MetaTrader 5 brokers for automated trading, and both run Expert Advisors without restriction. For an ONNX / ML EA the deciding factor is not "are EAs allowed" — it is execution quality. Here is the honest comparison.
Reminder
The broker executes orders; it does not run your model. ONNX inference runs on your machine or VPS. See what actually matters in a broker for an ONNX EA.
Accounts & cost
Both offer a raw-spread account from 0.0 pips plus commission — around $3.50 per lot (IC Markets charges per side; confirm current rates). For a systematic strategy that trades often, raw + commission is usually cheaper and more predictable than a marked-up "commission-free" spread.
| Broker | MT5 | EAs | Execution | Platforms | Get started |
|---|---|---|---|---|---|
| IC Markets | Yes | Allowed | Genuine ECN, 25+ liquidity providers, no last-look, no re-quotes | MT4 / MT5 / cTrader | Visit IC Markets → |
| Exness | Yes | Allowed | Fast, stable; broad account range | MT4 / MT5 | Visit Exness → |
Execution integrity (why it matters for an EA)
IC Markets runs a genuine ECN model: orders route to 25+ liquidity providers with no dealing desk, no last-look rejection, and no re-quotes. For a systematic EA, no last-look and no re-quote means fewer surprises between the price your model saw and the fill it gets. Independent 2026 tests put IC Markets slightly ahead on raw ECN execution speed, while Exness is consistently praised for smooth, stable operation across a broader range of account types.
Latency & where you run the EA
Execution also depends on latency between your terminal or VPS and the broker’s servers. Colocating near the matching engine helps latency-sensitive logic — but remember a forex VPS is CPU-only, so run GPU inference separately and let the VPS handle low-latency order execution.
Which to choose
For high-volume or latency-sensitive systematic trading where execution integrity is paramount, IC Markets’ genuine-ECN routing is the natural pick. If you want a broad range of account types and smooth all-round operation, Exness is a strong alternative. Verify current spreads, commissions, and regional availability before committing — and only publish links for brokers you have an affiliate agreement with and have tested.
Editorial standard
No earnings claims, no signals. Trading leveraged products carries a high risk of loss. Recommendations are independent of commission.
