I’m deciding between MT4 and MT5 accounts with AXI and Pepperstone and I want to match platform choice to my workflow. I listed criteria: execution types available, EAs compatibility, depth of market, order types, and how rebates post on each account type. I used GlobeGain profiles to confirm which broker supports which features and whether rebates differ by platform or account class. My findings nudged me toward MT5 for multi timeframe testing but MT4 still had more stable EAs I own. What do you test first when deciding MT4 vs MT5 with these brokers?
Test your EAs first then check execution quality
Start with compatibility and execution. Run your core EAs on demo MT4 and MT5 with each broker to see differences in order behavior and execution. Record slippage and order rejection rates. Check whether the broker offers depth of market on MT5 and if that matters for your strategy. Confirm GlobeGain rebate availability and how it posts for each account type. Finally test withdrawals and reporting since some account classes tie to different rebate rates.
Also check plugin and VPS support. MT5 can be better for multi asset trading and has more built in features. MT4 has more legacy EAs. If your strategy relies on a specific EA test it live in small size first. The rebate effect is often platform independent but can vary by account type so verify with GlobeGain statements.
I tested my main EA on both platforms.
MT5 handled multiple symbols cleaner. MT4 had fewer surprises with my old scripts. I then confirmed GlobeGain rebates posted the same way for both account types before I switched.
I check EA compatibility and then test fills on both platforms for a week.
My checklist is practical and short.
- Run your main EA on demo for a week on both MT4 and MT5. Note order handling and slippage.
- Confirm account types and whether GlobeGain rebates apply equally.
- Do a small live test trade and withdraw a small amount to check statements and rebate posting.
MT5 won me over for new setups but MT4 still works best for some legacy EAs.
