How Spread and Execution Kill Your EA Returns

Your EA didn’t fail — your broker conditions did.

The Hidden Killer of Good Strategies

Ever launched an EA that crushed the backtest…
…but then struggled in live trading?
→ It could be spread. Or slippage. Or latency.
But most traders don’t realize how lethal those can be — until it’s too late.

Spread: The Invisible Cost That Eats Your Edge

The spread is the difference between the bid and ask price.
It’s how brokers make money — but it’s also how your EA can silently lose profitability.

Let’s break it down:

Slippage and Execution Speed: The Silent Assassins

Slippage = price moves between signal and actual execution.
Execution speed = how fast your broker fills the order.

In volatile markets or slow servers, a few milliseconds can cost several pips — and that changes everything.
Even more so with EAs that depend on precise triggers or scalping logic.

How to Protect Your EA from Bad Execution

✅ 1. Choose Brokers with Tight, Variable Spreads (Not Fixed)

Fixed spreads often widen massively in real conditions — that’s worse than variable.
Choose low-latency ECN brokers with real-time data.

✅ 2. Use Real Spread in Backtests

Most testers default to ideal spreads (0.2–0.5 pips).
Simulate 2–3 pip conditions and see if your EA survives.

✅ 3. Avoid Over-Optimizing for Ideal Conditions

If your EA only works on backtest-perfect spreads, it’s not robust.
Your EA should still be profitable at 2x the base spread.

✅ 4. Use VPS with Low Latency

Execution delays = slippage.
A good VPS near your broker’s server can improve entry and exit precision, especially for short-term systems.

What We Do Differently

When we built our EAs, we tested them with:

• Variable spread simulation
• Slippage emulation
• Multiple brokers (low-cost + mainstream ones)
• Latency-aware logic (avoid fragile, timing-sensitive entries)

That’s why the DoIt GBP Master EA works on brokers like Fusion Markets, ICMarkets, and Pepperstone — even with real-world conditions.

Bonus Tip: Check Your Broker Execution Quality

Don’t just trust spreads listed on the website.
Use tools like MyFxBook broker comparisons or run a trade execution journal (we include one in our Telegram EA alert system).
If you see consistent slippage or delayed fills → change broker.
