User Manual
Everything you need to go from receiving your EA file to fully automated XAUUSD trading — explained step by step, for complete beginners.
⚡ Quick Start Overview
Four steps from zero to live. Each is covered in detail below — this is just the map.
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, places trades at the close of each kill zone session, manages them with an aggressive trailing stop, 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.
How it works (in plain English)
The EA places orders across 4 zones daily — three kill zones (Tokyo, London, New York) and a daily breakout zone based on the previous day's high and low. That's up to 8 pending orders per day, all managed automatically.
System Requirements

If your chart still looks the same as before, the EA did not load correctly.NEXUS AI v1.0 initialised — XAUUSD Multi-Session Breakout System — ONLINE. If you see an error message instead, refer to Section 16 (Troubleshooting).Risk Settings — Choosing Your Risk Mode
Nexus AI offers four risk modes. You configure these in the Inputs tab when attaching the EA (or by right-clicking the chart → Expert Advisors → Properties while the EA is running).
| Mode | Setting | Description | Best For |
|---|---|---|---|
| Fixed lot | Auto lot = false | Always trades the exact lot size you enter in Fixed lot size. Simple but doesn't scale with account growth. | Beginners, small accounts |
| % Account Risk | Auto lot = true | Calculates lot size so that each trade risks a percentage of your balance (set in Risk % for auto lot). Scales automatically as your balance grows or shrinks. | Most users — recommended |
| Fixed cash | Custom | Risks a fixed cash amount per trade regardless of balance. | Fixed budget traders |
Suggested risk levels
| Risk Level | Risk % | Expected Monthly* | Max Drawdown Risk |
|---|---|---|---|
| Conservative | 2–3% | ~8–15% per month | Low |
| Moderate | 5% | ~20–30% per month | Medium |
| Aggressive | 10% | 40–60%+ per month | Higher |
*Estimates based on ~85% win rate and live subscriber results. Individual results vary. Past performance does not guarantee future results.
Session Times & Kill Zones
The EA is pre-configured with the correct kill zone times in broker time (UTC+2). Unless your broker uses a different timezone offset, you do not need to change these.
| Zone | Start (UTC+2) | End (UTC+2) | Orders Placed |
|---|---|---|---|
| Tokyo Kill Zone | 03:00 | 07:00 | Kill zone window in broker time (UTC+2). Orders placed when zone closes. |
| London Kill Zone | 09:00 | 12:00 | BuyStop above high, SellStop below low |
| New York Kill Zone | 14:00 | 17:00 | BuyStop above high, SellStop below low |
| Daily Breakout | Always on | End of day | BuyStop above prev day high, SellStop below prev day low |
| Order Deletion | 23:30 | — | All unfilled pending orders cancelled |
Trailing Stop & Break-Even
The trailing stop engine is the core of Nexus AI's edge. The exact parameters are proprietary and configured optimally for XAUUSD kill zone volatility. What you need to know as a user:
Filters & Protection Settings
Spread Filter
The EA will not place new orders if the spread exceeds your maximum. For XAUUSD, a spread of 20–30 points (2–3 pips) is normal during kill zones. Set Spread maximum to 30 as a starting point (0 = no limit).
News Filter
When enabled, the EA reads a CSV file containing upcoming economic events and pauses trading before/after high-impact news. To use this:
- Download a news calendar CSV (Forex Factory or Myfxbook both offer exports)
- Save it to: MQL5/Files/news/newshistory.csv
- Set Enable news filter = true
- Set your stop window (default: 15 minutes before and after)
If you don't have a news CSV file, leave the news filter disabled.
Day of week filters
By default the EA trades Monday through Friday. You can disable individual days (e.g. disable Friday to avoid weekend gap risk) by setting the relevant Trade on [day] input to false.
Daily drawdown guard
Set Maximum daily drawdown % to a percentage of your balance. If the EA loses more than this in a single day, it closes all positions and stops trading until the next day. Recommended: 5% for standard accounts, 3–4% for prop firm accounts.

VPS Setup — Running 24/5
A VPS (Virtual Private Server) is a Windows computer in a data centre that runs 24 hours a day. You connect to it remotely from your PC or phone. For Nexus AI, a VPS is strongly recommended because:
- The Tokyo kill zone runs 03:00–07:00 UTC+2
- Your home PC may turn off, restart, or lose connection
- A VPS near your broker's server gives faster order execution
Recommended VPS providers
| Provider | Monthly Cost | Location | Notes |
|---|---|---|---|
| Contabo | ~€5–10 | EU / US / Asia | Excellent value. Good for most brokers. |
| ForexVPS.net | ~$10–30 | Multiple | Specialised for trading. Low latency. |
| Vultr | ~$6–12 | Global | Choose location closest to broker server. |
| MT5 built-in VPS | Free* | Varies | Available in MT5 if your broker offers it. |
VPS setup checklist
Choosing the Right Broker
Nexus AI works with any MT5 broker that offers XAUUSD. For best results:
| Feature | What to Look For | Why It Matters |
|---|---|---|
| Account type | ECN or STP | Tighter spreads on XAUUSD during kill zones. Avoid Market Maker accounts where possible. |
| XAUUSD spread | Under 30 pts (3 pips) | High spreads eat into the small bursts the EA is designed to capture. |
| Execution speed | Under 100ms | Kill zone entries happen in seconds. Slow brokers mean worse fills on pending orders. |
| Minimum lot size | 0.01 lots | Required for the % risk mode to size correctly on smaller accounts. |
| Server location | Same region as VPS | Host your VPS close to your broker's server for best execution. |
Popular brokers used by Nexus AI subscribers include: IC Markets, Pepperstone, Tickmill, FTMO (funded).
Pre-Launch Checklist
Go through this checklist before leaving the EA running unattended on a live account.
Troubleshooting
- Is the chart set to XAUUSD? (Not GOLD, XAUUSDT, or any other symbol)
- Is the WebRequests URL added correctly in Tools → Options → Expert Advisors?
- Is your licence key pasted correctly with no extra spaces?
- Is your subscription still active? Check at nexusai.io/#license
- Check the Experts log (Ctrl+T → Experts tab) for any error messages
- Verify the current broker time is within a session window (e.g. 09:00–12:00 for London)
- Check the spread — if it's above your Spread maximum setting, orders will be blocked
- Make sure the daily drawdown guard hasn't triggered (check the EA panel)
- Ensure AutoTrading is enabled (green button in toolbar)
NexusAI.ex5 into the correct MT5 installation's MQL5/Experts folder. Each MT5 instance (different brokers, VPS vs local) has its own separate data folder. Right-click Expert Advisors in Navigator → Refresh.Frequently Asked Questions
Can I run the EA on multiple charts at once?
No — the EA should only run on one XAUUSD H1 chart per MT5 account. Running it on multiple charts of the same account will cause duplicate orders and conflicting management logic. You can run it on multiple separate accounts (up to your seat limit of 2).
What happens to open trades if MT5 closes or loses connection?
Open positions remain on your broker's server regardless of whether MT5 is connected. However, the trailing stop and break-even management will stop functioning while MT5 is disconnected. This is why a VPS is critical — it keeps MT5 running continuously.
Can I change the take profit and stop loss?
Yes — Take profit (pips) and Stop loss (pips) are both configurable in the Inputs tab. The defaults (200 TP / 100 SL) are calibrated for XAUUSD H1. If you change these, test thoroughly on a demo account first.
How do I update the EA when a new version is released?
When a new version is released, you'll receive an email with the updated NexusAI.ex5 file. To update: (1) remove the EA from the chart (right-click → Expert Advisors → Remove), (2) overwrite the old file in the Experts folder with the new one, (3) refresh Navigator and re-attach the EA with your key.
Why did the EA remove itself from the chart?
Three reasons cause automatic removal: (1) Invalid or expired licence key, (2) Wrong symbol — the EA is XAUUSD only, (3) A critical error during initialisation. Check the Experts log for details.
My subscription has lapsed — what happens?
When you resubscribe, your licence key is reactivated automatically. Simply reattach the EA to your chart (or restart MT5) and it will validate successfully on the next load.
Can I use this on a funded/prop firm account?
Yes — Nexus AI places pending orders and manages them normally, which is generally compatible with prop firm rules. However: (1) Check your prop firm's EA policy, (2) Set the Daily Drawdown Guard conservatively (3–4% for typical 5% daily limit prop firms), (3) Always test on the evaluation account before using on a funded account.
