MT5 Expert Advisor
XAUUSD Only
v1.05
⚡ Quick Start Overview
Four steps from zero to live. Each is covered in detail below — this is just the map.
Section 0
Introduction
Nexus AI is a MetaTrader 5 Expert Advisor (EA) — a piece of automated trading software that runs directly inside your MetaTrader 5 platform. Once set up, it requires no input from you. It monitors XAUUSD around the clock, identifies high-probability entries across multiple global sessions, manages them via the proprietary TSLE, and closes them automatically.
You receive a single file: NexusAI.ex5 — a compiled, ready-to-run EA. You do not need to write any code or understand programming to use it.

The EA places orders across multiple sessions daily — covering three major global trading windows plus a daily breakout zone based on the previous day's high and low. Up to 8 pending orders per day, all managed automatically.
💡
Important: Nexus AI only works on XAUUSD (Gold). If you attach it to any other symbol it will display a warning message and remove itself from the chart automatically.
Section 0.1
System Requirements
You need MetaTrader 5 — not MetaTrader 4. MT4 is a different platform and will not work with NexusAI.ex5. Download MT5 from your broker's website for free. Most brokers offer both; make sure you select MT5.
✓
A broker offering XAUUSD on MT5
Your broker must offer the Gold symbol (usually called XAUUSD) on MT5. A Raw or ECN account is required for best results — Raw accounts charge a small commission per trade but offer near-zero spreads, ensuring price fills accurately at your pending order levels. Avoid Standard or Market Maker accounts. Popular options include IC Markets (Raw), Pepperstone (Razor), Tickmill (Pro), and FTMO (for funded accounts).
MT5 runs on Windows. You can use your own Windows PC to test, but for live trading a Windows VPS is strongly recommended so the EA runs 24/5 without your computer being on. Nexus AI covers sessions from 03:00 UTC+2 — you'll be asleep. See Section 13 for VPS setup.
✓
Active Nexus AI subscription & licence key
You need an active £199/month subscription and a valid licence key. Your key is automatically emailed to you on subscription. If you've lost it, retrieve it at any time from the
Licence Portal. Your key looks like:
NX-XXXX-XXXX-XXXX
✓
Stable internet connection
The EA validates your licence against our server each time it loads, and places trades in real time. A stable connection is essential — another reason to use a VPS rather than a home internet connection.
Section 1
Quick Start — 4 Steps to Live Trading
If you're comfortable with MT5 and just want the essentials, this section covers the entire setup in four steps. Each step is expanded in full detail in Sections 2–7.
Your licence key was emailed to you automatically when you subscribed. Check your inbox (and spam folder) for an email from
[email protected]. If you can't find it, retrieve it at any time from the
Licence Portal. It looks like:
NX-LT9D-N6R0-CZ-MAM5J
2
Place NexusAI.ex5 in your MT5 Experts folder
In MT5 go to File → Open Data Folder. Inside that folder, open MQL5 then Experts. Copy NexusAI.ex5 into that folder. Restart MT5 (or press F5 in the Navigator).
3
Allow WebRequests and add the licence server URL
In MT5: Tools → Options → Expert Advisors. Tick "Allow WebRequests for listed URLs". Add this URL exactly:
https://nexusai-license.nxsai.workers.dev
Click OK. Without this step the licence will not validate and the EA will not run.
4
Attach to XAUUSD M1 chart and enter your key
Open a XAUUSD chart, set it to M1 (1-minute) timeframe. In the Navigator panel (Ctrl+N), expand Expert Advisors, find NexusAI, and drag it onto the chart. In the Inputs tab, paste your licence key into the License key field. Click OK. The AI dark chart theme will apply and the on-chart panel will appear. You're live.
Section 2
Receiving Your EA File
After subscribing, you will automatically receive a welcome email containing your licence key and a download link for NexusAI.ex5. This is the only file you need.
⚠️
File type: The file ends in .ex5 — this is a compiled MetaTrader 5 Expert Advisor. Do not try to open it as a normal file. It will only work inside MT5.
Where to save it
Save NexusAI.ex5 somewhere easy to find on your computer — your Downloads folder or Desktop is fine. You'll move it into the correct MT5 folder in the next step.
💡
If you subscribed and haven't received the email within 5 minutes, check your spam folder. You can also retrieve your key and download link at any time from the
Licence Portal.
Section 3
Installing the EA in MetaTrader 5
Launch MetaTrader 5. Make sure it's connected to your broker (you'll see the connection status in the bottom right — it should say your broker name and show a green connection indicator).
In the MT5 menu bar, click File → Open Data Folder. This opens a Windows Explorer window showing the MT5 data directory. Every installation of MT5 has its own data folder — make sure you're in the right one (the one connected to your broker).
3
Navigate to the Experts folder
Inside the data folder, open the MQL5 folder, then open Experts. The full path looks like this:
C:\Users\YourName\AppData\Roaming\MetaQuotes\Terminal\[ID]\MQL5\Experts\
You can create a subfolder called NexusAI inside Experts to keep things tidy, but it's not required.
4
Copy NexusAI.ex5 into the Experts folder
Copy (or drag) NexusAI.ex5 from wherever you saved it into the Experts folder you just opened.
5
Refresh the Navigator in MT5
Back in MT5, open the Navigator panel with Ctrl + N (or View → Navigator). Right-click on Expert Advisors and select Refresh. You should now see NexusAI appear in the list under Expert Advisors.
💡
If you don't see NexusAI in the Navigator after refreshing, double-check that you copied the file into the correct MQL5/Experts folder inside the data directory. Some computers have multiple MT5 installations with different data folders.
Section 4
Allow WebRequests — Critical Step
Nexus AI validates your licence key against our server every time the EA loads. For this to work, you must tell MT5 to allow the EA to make web requests to our server URL. If you skip this step, the licence will fail and the EA will remove itself from the chart.
🚫
Mandatory (v1.05): Without this step, the EA cannot validate your licence and will not run. Unlike earlier versions, there is no offline fallback — online validation is required every time the EA loads.
In the MT5 menu, click Tools → Options (or press Ctrl+O).
2
Go to the Expert Advisors tab
In the Options window, click the Expert Advisors tab at the top.
Check the box that says "Allow WebRequests for listed URLs". A text field will appear below it where you can add URLs.
4
Add the Nexus AI licence server URL
In the URL field, type or paste this URL exactly as shown (including the https://):
https://nexusai-license.nxsai.workers.dev
Click Add. Then add the news calendar URL the same way:
https://nfs.faireconomy.media
Both URLs should appear in the list. Click OK.
Click OK to save the settings. MT5 will now allow the EA to contact our licence server.
💡
If you're using a VPS, you need to do this step on the VPS's MT5 installation, not just your home PC's MT5. Each MT5 installation has its own settings.
Section 5
Attaching the EA to a XAUUSD Chart
In MT5, click View → Market Watch (or Ctrl+M) to open the Market Watch panel. Find XAUUSD in the list. If you don't see it, right-click in Market Watch and select Show All or search for it. Once you see XAUUSD, double-click it to open a chart, or right-click and select Open Chart.
!
Set the timeframe to M1 (1 Minute)
Nexus AI is designed and calibrated for the M1 (1-minute) timeframe on XAUUSD. At the top of the chart, click M1 in the timeframe buttons. The EA will work on other timeframes but results may differ — M1 is the recommended and intended setting.
2
Drag NexusAI onto the chart
In the Navigator panel (Ctrl+N), expand Expert Advisors. Find NexusAI. Drag it from the Navigator onto the XAUUSD M1 chart. A settings dialog will open.
!
Enable "Allow Algo Trading" in the dialog
In the EA dialog that opens, click the Common tab and make sure "Allow Algo Trading" is ticked. Without this the EA will load but won't be able to place any trades.
Before clicking OK, click the Inputs tab at the top of the dialog. This is where you'll enter your licence key and configure risk settings. See the next section.
💡
Make sure the AutoTrading button in the MT5 toolbar is enabled (green). It's in the top toolbar and looks like a play button with "AutoTrading" next to it. If it shows red/disabled, click it to enable it.
Section 6
Entering Your Licence Key
With the EA dialog open on the Inputs tab, you'll see a list of all configurable parameters. The first group is Licensing.
🔑
Find "License key" in the Inputs tab
In the Inputs tab, look for the group labelled ═══ Licensing ═══ at the very top. Below it you'll see a row labelled License key with an empty text field on the right.
Click the Value field next to License key. Paste your key using Ctrl+V. Your key should look like:
NX-LT9D-N6R0-CZ-MAM5J
Make sure there are no spaces before or after the key. The field should contain only the key itself.
2
Configure your risk settings (optional — can change later)
While you have the Inputs dialog open, you can also set your risk preferences. See Section 8 for a full guide to risk settings. For your first run, the defaults are safe to use — the EA will trade with a fixed 1.0 lot unless you change it.
Click OK to apply all settings and start the EA. The EA will immediately attempt to validate your licence key against our server. This takes 1–3 seconds.
🚫
If the EA disappears from the chart after clicking OK, it means either: (a) your licence key is incorrect, (b) the WebRequests URL was not added correctly (Section 4), or (c) the EA was placed on a non-XAUUSD chart. Check each of these and try again.
Section 7
Verifying the EA is Live
When Nexus AI loads successfully, several things happen immediately:
✓
The AI dark chart theme applies
The chart background turns near-black (#0A0C12), bull candles become cyan-teal, and bear candles become coral red. If your chart still looks the same as before, the EA did not load correctly.
✓
The on-chart panel appears
A dark terminal-style panel appears in the top-left corner of the chart showing: EA name and version, current balance, open P&L, session status (Tokyo/London/NY), and licence information. Check that it shows License: Active.
✓
The Experts log shows a success message
Open the MT5 Toolbox (Ctrl+T), click the Experts tab. You should see a log entry like: NEXUS AI v1.05 initialised — XAUUSD Multi-Session Breakout System — ONLINE. If you see an error message instead, refer to Section 16 (Troubleshooting).
✓
Blue hat icon appears on the chart
In the top-right corner of the chart, a blue hat icon confirms the EA is running with AutoTrading enabled in MT5. If the hat appears grey, AutoTrading is disabled — click the AutoTrading button in the toolbar to enable it.
