MetaQuotes schedules MT4 build 1490 deployment
| Platform | Build Version | Release Date | Developer |
|---|---|---|---|
| MetaTrader 4 (MT4) | 1490 | October 2, 2026 | MetaQuotes |
Software developer MetaQuotes has established Friday, October 2, 2026, as the release date for MetaTrader 4 build 1490. As one of the long-standing terminal environments across retail brokerages and funded account firms, MT4 platform updates modify core client application binaries and connection protocols to optimize system reliability and platform security.
When MetaQuotes releases a build update, the rollout typically occurs in stages across global broker server networks. Once a broker or proprietary trading firm updates its trade server backend, individual client terminals receive the updated binaries upon launching or reconnecting to the trading infrastructure.
Why build updates matter for prop traders and EA execution
For retail traders and evaluation account holders, system updates on core platforms introduce practical execution considerations. Although routine build releases primarily target performance stability and security patches, subtle changes to terminal handling can impact live trading environments, algorithmic order routing, and client-side logging.
Traders using automated Expert Advisors or custom indicators must remain cautious during terminal update cycles. Minor changes to MQL4 execution handling or library dependencies can occasionally disrupt trade copiers or custom risk management tools. Ensuring that automated scripts execute seamlessly requires checking terminal logs immediately after an update is applied.
Furthermore, maintaining operational uptime is critical for traders operating under strict prop firm risk rules. Unscheduled platform restarts during volatile market sessions can leave open positions unmanaged if stop-loss commands rely on client-side EA trailing stops rather than server-side parameters. Checking execution and platform stability guidelines helps traders minimize unnecessary exposure during platform maintenance windows.
Proprietary firms such as FTMO maintain stringent infrastructure requirements to ensure fair pricing and minimal latency across trading terminals. When platform providers release structural builds, prop firms coordinate server updates during off-peak weekend hours or low-volume session gaps to reduce execution friction. Traders relying on external trade synchronization should review their trade copier configurations to confirm uninterrupted connectivity across updated terminals.
What traders should watch next
Ahead of the October 2, 2026 release date, traders using MT4 should prepare their trading environments for client-side terminal prompts. While MetaQuotes updates are delivered seamlessly through built-in auto-update mechanics, taking proactive steps ensures uninterrupted session management:
- Restart desktop terminals: Reboot your MT4 platform during non-trading hours after October 2, 2026, to ensure your client build synchronizes with broker servers.
- Verify automated tools: Test custom indicators, scripts, and EAs on demo instances to verify MQL4 compatibility following the build 1490 update.
- Monitor broker communications: Check announcements from your broker or prop firm regarding scheduled server maintenance or temporary platform downtime.
- Review multi-platform alternatives: Traders seeking alternative execution environments can evaluate updates across competing trading platforms to diversify platform risk.
Frequently asked questions
When will MT4 build 1490 be released?
MetaQuotes is scheduled to release MetaTrader 4 build 1490 on Friday, October 2, 2026. Individual brokerages and proprietary trading firms will deploy the build update across their server networks according to their internal maintenance schedules, meaning client terminals will receive the update upon their next system restart.
Do traders need to manually download MT4 build 1490?
No manual installation or software package download is required for desktop users. The MetaTrader 4 client terminal automatically detects, downloads, and applies build 1490 when you restart the application after your broker or prop firm updates its trading server infrastructure.
Could MT4 build 1490 affect Expert Advisors or custom indicators?
Standard MQL4 programs generally maintain backward compatibility across build updates. However, custom Expert Advisors, third-party trade copiers, or indicators relying on external DLL libraries should be tested on a demo account immediately following the update to verify continuous, error-free execution.
