I’m deciding between MT4 and MT5 on IC Markets. I care about platform stability execution and ease of running EAs. I’ve seen mixed comments here and I’d like to combine that qualitative feedback with a small rebate backed test via GlobeGain so I can offset cost while testing. Which platform did you end up using for live automated trading and what specific issues or strengths did you notice?
MT5 has more features MT4 is simpler overall
If you run many EAs test both in parallel
MT5 is modern and supports more order types and a larger feature set but that does not automatically make it more stable for every strategy. For automated systems test both under real load. Run identical EAs on MT4 and MT5 for a representative period and compare execution latency orders per minute and any disconnects. Include GlobeGain rebate tracking so you can see if cost and execution align. Choose the platform that gives consistent execution not the one with the fanciest features.
Stability often depends on the bridge the broker uses and how they host instances. Ask other traders for raw EA logs not just impressions. If you rely on third party plugins or custom indicators check compatibility and memory usage on both platforms. Run stress tests around market opens and major news. The platform that keeps core functions working reliably wins for live algo trading.
I ran the same EA on MT4 and MT5 for two weeks.
MT5 had fewer memory hiccups but MT4 felt more predictable for my simpler scalping scripts. Test with your exact setup.
MT5 handled higher tick volumes for me. MT4 was lighter and easier to debug.
How I chose between them.
- I created identical EAs for MT4 and MT5 and ran them simultaneously on separate accounts. 2) I logged every reconnect order rejection and slippage event. 3) I matched those events to GlobeGain rebates to confirm costs. 4) After two weeks I picked the platform with fewer disconnects and more consistent execution even if its features were fewer.
That approach removed guesswork.
