Choosing a broker for an automated strategy
Your broker decides the spreads, slippage and execution your EA actually trades on — and a backtest run on one broker's data can behave very differently on another. This is a checklist of what to weigh, not a ranking. Where TradeAquila shows partner brokers, they are clearly disclosed affiliate links — never a ranking or an endorsement.
Execution model
Whether you trade against the market or against the broker changes everything for an EA.
- ECN / raw-spread / STP routes orders to a liquidity pool; a dealing-desk market maker can take the other side of your trade.
- Ask about requotes, slippage on news, and whether the broker profiles and limits automated or scalping accounts.
- A backtest is only as honest as the feed it ran on — the same EA can behave very differently on another broker.
All-in cost (spread + commission + swap)
Compare the total cost per round turn, not the headline spread.
- A "zero spread" account with high commission can cost more than a wider-spread, no-commission one.
- If you hold overnight, swap / financing can quietly dominate the cost of a low-timeframe system.
- TradeAquila's live monitor shows the all-in cost your account actually pays per round trip — measure it before you commit size.
Server location & latency
For anything fast, the distance to the trade server is a real cost.
- Find where the broker's MT4/MT5 trade server is physically hosted (often London/LD4, New York/NY4 or Tokyo).
- Scalping and high-frequency EAs are the most latency-sensitive; swing systems barely care.
- If latency matters, place your VPS in the same data-center region as the trade server.
Symbol specifications
Contract specs decide how your lot sizing and risk actually behave.
- Contract size, tick value, minimum lot and lot step, leverage and margin requirements.
- Trading hours, symbol suffixes (EURUSD vs EURUSD.m) and whether the symbols your EA expects even exist.
- Differences here are a common reason an EA that "worked" elsewhere misbehaves on a new account.
Regulation & fund safety
The edge is irrelevant if you cannot withdraw.
- A tier-1 regulator, segregated client funds and (where offered) negative-balance protection.
- A documented withdrawal track record and transparent legal entity.
- Treat unusually generous bonuses or leverage as a flag to investigate, not a feature.
Demo / forward-test parity
Test on what you will actually trade.
- Forward-test on the exact account type and trade server you intend to go live on.
- Demo feeds and execution can differ from live — confirm the divergence is small before scaling.
- After any broker switch, re-baseline and watch for drift.
