Installation & Setup

Step by step:

1. In MetaTrader 5, click **File → Open Data Folder**. Windows Explorer opens to the right MT5 instance. 2. Open `MQL5/Experts/`. 3. Copy your purchased `.ex5` file into that folder. If you received a `.set` preset file too, copy it into `MQL5/Presets/`. 4. Restart MetaTrader 5. 5. In the Navigator pane (Ctrl+N), expand **Expert Advisors**. Your EA appears. 6. Drag the EA onto the chart for the pair/timeframe shown on the product page. 7. In the inputs dialog, click **Load** and pick your `.set` file. Confirm. 8. Check that the AutoTrading button on the main toolbar is green. The EA smiley in the chart top-right corner should also be smiling.

If the EA smiley is sad, AutoTrading is disabled or the EA is missing permission to trade. See `/faq/troubleshooting#no-trades`.

Local desktop usage is fine for testing and short live sessions. For long-term automated trading you should run MT5 on a VPS for three reasons: 24/5 uptime regardless of your laptop sleep/network, sub-20 ms broker-server latency, and isolation from desktop crashes.

Recommended VPS spec for one EA on one account: - 2 vCPU - 4 GB RAM (8 GB if running multiple EAs) - 60 GB SSD - Windows Server 2019/2022 - Same region as your broker (London/Equinix LD4 covers most ECN brokers)

VPS providers we have tested: BeeksFX, FXVM, NYC Servers, and Vultr. We don't endorse a specific provider — pick by location, support, and price.

License terms are summarised in /legal/eula. The short version: one license = one trading account (with up to two device installations). If you switch brokers or open a new account, contact [email protected] — re-binding the license to a new account number is free and usually completed within 24 hours.

Multi-account use cases (e.g. running the EA on five accounts for different clients) require the Full or IB license tier. See the pricing calculator for the per-account cost.

The two failure modes a VPS fixes:

1. **Connectivity** — if your home internet drops while a position is open, the EA cannot adjust the stop-loss or exit on schedule. A managed VPS at the broker's data centre maintains the connection. 2. **Latency** — distance between your machine and the broker server matters for scalpers. A trade-execution round-trip of 100 ms vs 5 ms can cost an extra 0.5 pip per trade on average.

For low-frequency EAs (Trendopedia at H4, swing systems) you can get away without a VPS, but you still lose trades whenever the machine sleeps. Even a $5–10/month VPS is usually worth it.

The most common mistake at this step is attaching the EA to the wrong timeframe or wrong pair. EAs are designed for a specific market context — running Scalperology AI on H1 EURUSD will not produce the published statistics because it expects M1 XAUUSD ticks.

A correctly attached EA shows: - A smiling face icon in the top-right of the chart. - The AutoTrading button green in the main toolbar. - The EA's status panel rendering on the chart (if it has one). - Log entries in the Experts tab of the Toolbox panel.

If any of those are missing, see /faq/troubleshooting.

A `.set` file is a serialised snapshot of all EA input parameters. The product authors publish the recommended `.set` per market regime — for example, a low-risk preset for prop-firm rules and an aggressive preset for scaling accounts.

Replacing a `.set` mid-session does not require restarting the EA: open the chart, right-click the chart background → Expert Advisors → Properties, click Load on the new file, then OK. The EA picks up the new inputs on the next tick.

Our cloud `.SetAnalyze` system (paid tiers) auto-updates the recommended `.set` based on rolling out-of-sample tests on dedicated server fleets. See /cloud-adaptive for details.

Versioning policy: - **Patch (1.2.x)** — bug fixes, no input changes. Drop-in replacement. - **Minor (1.x)** — new inputs or features with backwards compatibility. Existing `.set` files keep working; new inputs use defaults. - **Major (x.0)** — breaking changes. Released `.set` files for the new version are published alongside.

Updates are free for the lifetime of your license. We email release notes to license holders and also publish the public changelog at /changelog.
