Server Selection (US East / EU Central)

What it is

Strateda operates dual-region servers for MT5 integration: US East and EU Central. When you configure the Expert Advisor, you select which server region it connects to. The right choice is the region closest to where your MT5 terminal is physically running — not where your broker's server is located.

To understand why, it helps to separate the two network paths involved:

Path 1 — MT5 terminal ↔ Strateda server (choose your region based on this)

Every candle, the EA and Strateda's backend make two round trips: the EA sends fresh market data to Strateda, and Strateda sends the resulting trade signal back to the EA. This round trip happens on every candle for every live strategy. Minimising this latency is the primary goal of region selection — and it's determined by the distance between your MT5 terminal and Strateda's server.

Path 2 — MT5 terminal ↔ Broker server (secondary — not what drives region selection)

Once MT5 receives a trade signal, it sends the order to your broker for execution. This is a single trip. Most brokers execute trades through infrastructure near major financial centres — primarily New York. A terminal running on a US East VPS is geographically close to this infrastructure, typically resulting in execution latency of 250–300ms. A terminal running in Europe is physically further away — typically 300–450ms or more, with greater variability. This means a US East VPS has a secondary advantage: shorter broker execution latency in addition to the shorter Strateda↔MT5 signal path. For EU-based users running MT5 locally, broker execution latency will be somewhat higher — this is a consequence of physical distance, not of Strateda's configuration.

How to access it

Server selection is configured in two places:

1. In the EA settings — When you attach the Strateda EA to a chart in MT5, the properties dialog includes a Server field. Select US East or EU Central.
2. In Strateda — The MT5 Integration settings in the platform allow you to view and confirm the active server region.

You can change your server selection at any time by modifying the EA properties in MT5. Stop any running live strategies before switching, then restart them after the EA reconnects on the new server.

What you see

The available server regions:

Region	Location	Choose if your MT5 terminal is running in…
US East	Eastern United States	North America — local machine or US-based VPS
EU Central	Central Europe	Europe — local machine or EU-based VPS (Frankfurt, London, Amsterdam, etc.)

After selecting a region, the EA connects and the Experts tab in MT5 displays the active server along with the connection status and approximate latency.

How to interpret it

Where is your MT5 terminal running?

This is the only question that determines your region choice:

• Local machine in the US → choose US East
• Local machine in Europe → choose EU Central
• VPS in the US (e.g., Amazon Lightsail us-east, New York) → choose US East
• VPS in Europe (e.g., Frankfurt, London, Amsterdam) → choose EU Central
• Unsure — check your VPS provider's data center location, or test both regions and compare the latency shown in the EA's Experts tab. The lower-latency region is the correct one.

Does broker location matter?

Broker execution latency is a secondary factor — it's a single trip, not a round trip, so it compounds less than the Strateda↔MT5 path. That said, most brokers execute trades through infrastructure near major financial centres, primarily New York. A US East VPS is geographically close to this infrastructure and benefits from both a short Strateda↔MT5 signal path and short broker execution latency.

For EU-based users running MT5 locally or on a European VPS, broker execution latency will be somewhat higher due to physical distance from NY infrastructure — typically 300–450ms versus 250–300ms from a US terminal. This is a real but secondary cost. The Strateda↔MT5 path still dominates the region selection decision because it involves two round trips per candle across the lifetime of the strategy.

If your MT5 terminal is on a European VPS: choose EU Central. The reduction in Strateda↔MT5 latency outweighs the broker execution distance. If you want to minimise both paths simultaneously, a US East VPS with US East Strateda region is the optimal setup.

Latency impact by strategy type

• Higher-frequency strategies (M1–M5, many trades) — Every candle involves a Strateda↔MT5 round trip. Lower latency here reduces signal delay and execution slippage cumulatively across hundreds of trades per year.
• Swing strategies (M30, H1, H4, D1) — Candle periods are long enough that a few extra milliseconds have no practical impact. Choose the correct region anyway — there is no downside.
• Volatile instruments (GBP pairs, indices, gold) — Price can move meaningfully in the extra time added by a suboptimal server path during fast markets.

Switching servers

Changing servers is non-destructive. Your strategies, configurations, and historical data are unaffected. The process:

1. Stop any running live strategies in Strateda.
2. In MT5, open the EA properties on the chart and change the Server setting.
3. The EA disconnects from the current server and reconnects to the new one.
4. Confirm the Connected status in the Experts tab.
5. Restart your live strategies in Strateda.

The navbar region selector

The region dropdown in the Strateda navigation bar is separate from the EA region setting — and it does more than just display preference. It determines your active management context: which EA connections are visible and which live strategies you can start, stop, and monitor.

Each region maintains its own registry of connected EAs and running live strategies:

• EAs connected to US East are visible only when the navbar is set to US East
• EAs connected to EU Central are visible only when the navbar is set to EU Central
• A live strategy started in US East appears as not running when you switch the navbar to EU Central — it is running, just on the US East server, which is not visible in the EU context

This means your navbar region must match the EA region before you can activate a live strategy. If you configured your EA to connect to US East, switch the navbar to US East first — otherwise the account selector in the activation popup will not show that EA connection.

Auto Region — selecting Auto in the navbar routes you to the nearest region based on your IP address. This is the default for most users and works well if all your EAs are configured to match your geographic location. If you intentionally run EAs in a region that differs from your physical location (for example, a US East VPS while you are based in Europe), set the navbar manually to match.

Each region has its own login session. You log in once per region, and switching back to a region you have already authenticated in reuses the existing session without requiring a new login.

The relationship between navbar region and EA region setting

These two must be consistent for everything to work:

EA region setting	Navbar region	Result
US East	US East	✓ EA visible, strategy can be activated
EU Central	EU Central	✓ EA visible, strategy can be activated
US East	EU Central	✗ EA not visible in account selector
EU Central	US East	✗ EA not visible in account selector

Backtesting is not affected by navbar region. Backtest jobs run on the computation backend regardless of which region is selected in the navbar. Region selection is only relevant for live strategy management.

Example

A trader has two VPS machines — one in Frankfurt, one in New York — each running an MT5 terminal connected to a different broker account.

• Frankfurt MT5 — EA configured to eu.strateda.com (EU Central). Signal latency in the Experts tab: ~12ms.
• New York MT5 — EA configured to us.strateda.com (US East). Signal latency in the Experts tab: ~8ms.

To manage the Frankfurt strategy, the trader sets the navbar to EU Central — the Frankfurt EA connection appears in the account selector, and the live strategy runs on the EU server.

To manage the New York strategy, they switch the navbar to US East — the New York EA connection appears, and that strategy runs on the US server. The Frankfurt strategy now shows as not running in this view — it is still running on the EU server, just not visible from the US context.

Both strategies run simultaneously. The trader checks in on each by switching navbar regions as needed.
