FXCITYPRO OPERATIONS GUIDE
Running multiple FXCityPro EAs safely and clearly
A practical guide to separate MT4 terminals, combined Grid exposure, Auto Lot, broker conditions and reliable VPS operation for FXCityPro Alpha X 2.0, FXCityPro_EUR 3.0v and FXCityPro_JPY.
MAP THE PRODUCTS FIRST
Three EAs, three exact chart assignments
Do not treat FXCityPro as one universal robot. Each licensed EX4 file has its own product page, chart, monitoring profile and Strategy Tester report.
FXCityPro_EUR 3.0v
The more active EURJPY M15 edition, with configurable fixed-lot or equity-based position sizing.
- Chart: EURJPY M15
- Live profile: fxcitypro_eur
- Backtest: StrategyTester3.htm
FXCityPro_JPY
A dedicated USDJPY system for the M30 chart, with risk settings that must be assessed together with the rest of the account.
- Chart: USDJPY M30
- Live profile: fxcitypro
- Backtest: StrategyTesterJPY.htm
Two EAs use EURJPY, but they are not interchangeable
Alpha X uses EURJPY H1; FXCityPro_EUR uses EURJPY M15. Running both on the same trading account can concentrate exposure to the same currency pair even when their terminals and Magic Numbers are separate.
TERMINAL ARCHITECTURE
Give every EA its own MT4 installation
The recommended layout is one EA, one chart and one terminal installation. This makes configuration, logs, templates and restarts easier to identify and prevents one terminal workspace from becoming ambiguous.
Create named installations
Install the broker's MT4 into separate folders and name the shortcuts, for example Alpha-X-H1, EUR-3-M15 and JPY-M30. Use File → Open Data Folder in each terminal to confirm that their data folders differ.
Install one licensed EX4
Place only the intended FXCityPro file in that terminal's MQL4/Experts folder. The account number logged into MT4 must match the account for which the file was registered.
Keep one controlled chart
Open only the required symbol and timeframe for that EA, apply the delivered settings, and record the terminal name, chart and Magic Number used.
Understand what isolation does
Separate terminals isolate files, charts and logs. They do not divide account equity, margin or market exposure when all terminals log into the same trading account.
Terminal separation is not financial separation
If three terminals connect to one MT4 account, all three EAs still use the same balance, equity and free margin. Separate trading accounts provide stronger risk separation, but only when your license allowance and broker setup permit it.
BEFORE INSTALLATION
Prepare the account, platform and files
Most installation problems are easier to prevent than to repair. Complete these checks before copying the licensed EX4 file into MetaTrader 4.
Confirm the MT4 account number
The license is prepared for the account number supplied after purchase. Copy the number from the MT4 Navigator or account window and make sure the demo or real account type is correct.
Use MetaTrader 4 desktop
An EX4 Expert Advisor is installed in the desktop terminal. The mobile MT4 application can monitor an account but cannot host or run the EA itself.
Choose the exact edition
Check the filename and the product you purchased. Alpha X, FXCityPro_EUR and FXCityPro_JPY require different charts and must not be treated as one universal robot.
Start with a demo account
A demo run confirms that the license is recognized, the broker symbol and permissions are correct, and the terminal is stable before any real capital is exposed.
Keep the original licensed file
Store the delivery email and an untouched backup of the EX4 file. Renaming or modifying protected files may make troubleshooting unnecessarily difficult.
Update and restart MT4
Use a current broker build of MetaTrader 4. Restarting the terminal before installation clears many temporary interface and Navigator issues.
MT4 INSTALLATION
Install FXCityPro step by step
The exact menu wording can vary slightly between broker builds, but the folder and permission sequence is the same.
Open the MT4 data folder
In MetaTrader 4 select File → Open Data Folder. Do not guess the installation directory in Windows Explorer because a computer can contain several different terminal data folders.
Open MQL4 and Experts
Inside the active data folder open MQL4 and then Experts. This is the directory where the licensed FXCityPro EX4 file belongs.
Copy the EX4 file
Copy only the edition licensed for this account into the Experts folder. Keep the filename supplied by support unless you have been instructed otherwise.
Refresh or restart
Return to MT4, right-click Expert Advisors in the Navigator and select Refresh. A full terminal restart is the most reliable option if the EA does not appear.
Open the correct chart
Open EURJPY H1, EURJPY M15 or USDJPY M30 according to the edition. Confirm that the symbol in the chart header is correct, including any broker suffix.
Attach the EA
Drag FXCityPro from Navigator to the chart. Review the Inputs tab and keep the official default configuration for the first controlled demo test.
Allow automated trading
In the Common tab allow live trading when you are ready, then enable the AutoTrading button in MT4. The platform and the EA both need permission.
Check the status
Look for the normal EA status on the chart and read the Experts and Journal tabs. License, symbol or permission messages are more useful than repeatedly reinstalling the same file.
COMBINED GRID EXPOSURE
Measure the basket, not just the first trade
Here, Grid exposure means the account-level risk created when an EA manages several positions or when several EAs hold related positions at the same time. It does not mean that all FXCityPro products use identical Grid or Martingale logic.
Total open lots
Add the volume of every open position across all terminals. A small first order can become a much larger account-level exposure when a sequence develops.
Pair concentration
Alpha X and FXCityPro_EUR both trade EURJPY. Their signals can overlap, so separate Magic Numbers do not remove correlation or duplicate directional exposure.
Floating drawdown
Monitor equity, floating profit or loss and free margin for the complete account. Closed profit from one EA does not neutralize an active losing basket in another.
Costs over time
Include spread, commission and swap for all positions. Costs can expand during volatile or illiquid periods and may materially change a multi-order sequence.
No Martingale is not the same as no risk
Alpha X explicitly avoids Martingale lot doubling. That statement does not guarantee a fixed drawdown, eliminate correlation, or make combined exposure with other EAs safe.
POSITION SIZING
Treat Auto Lot as an account-wide risk control
Equity-based sizing can be convenient, but every EA may read the same account value. Without a portfolio-level plan, several EAs can each size positions as if the full balance were available to that strategy alone.
Start with fixed lot
For the first demo and controlled live test, a small fixed lot is easier to audit. It separates installation issues from changing position-size calculations.
Do not allocate the same equity twice
If two or three EAs use equity-based sizing, reduce each allocation so their combined worst-case exposure fits one account limit.
Expect size to change
Deposits, withdrawals, realized results and floating equity can affect an automatic lot calculation. Check the next permitted lot before and after account changes.
Respect broker volume rules
The requested size must fit the broker's minimum lot, lot step and maximum volume. Invalid volume errors should be corrected from symbol specifications, not guessed.
There is no universally safe Auto Lot value
Balance, leverage, contract size, open baskets, broker costs and personal loss limits differ. Test the delivered settings on demo, change one documented input at a time and keep enough free margin for adverse movement.
BROKER AND VPS
Execution conditions can change the result
Two MT4 accounts can behave differently even when they use the same EA and inputs. Price feeds, spreads, commission, swaps, trading hours, stop levels, latency and order execution all matter.
Symbol suffix
Symbols such as EURJPY.a or USDJPYpro may still represent the correct pair. Confirm that the chart is tradable and that the EA recognizes the broker naming format.
Spread and commission
The visible spread is only one cost. Compare normal and volatile sessions, commission per lot and swaps when positions may remain open.
Order execution
Slippage, rejected orders and broker stop-distance rules can alter entries or management. Review the Experts and Journal logs instead of assuming every difference is an EA fault.
VPS continuity
A VPS can keep MT4 online while the home computer is off. Choose a stable location near the broker, disable automatic terminal shutdowns and verify that MT4 restarts after maintenance.
A VPS does not correct a bad setup
It improves continuity and may reduce latency, but the correct account, licensed file, pair, timeframe, permissions and risk settings must already be in place.
VERIFY EACH SOURCE
Keep live monitoring and Backtests mapped to the correct EA
FX Blue shows the history made public for a monitored account; a Backtest is a historical simulation under selected assumptions. They answer different questions and neither guarantees future results.

TROUBLESHOOTING
Typical Forex EA mistakes and how to diagnose them
Start with the exact message in MT4. The Experts and Journal tabs usually narrow the problem faster than deleting files or changing multiple inputs at once.
| Problem | Likely cause | What to check |
|---|---|---|
| The EA is not visible in Navigator | The EX4 was copied into a different terminal data folder, or Navigator was not refreshed. | Use File → Open Data Folder in the same MT4 terminal, confirm MQL4/Experts and restart MT4. |
| The EA is on the chart but does not trade | AutoTrading, live-trading permission or market conditions may prevent execution. | Confirm both permissions, read the chart message and logs, then allow the strategy to wait for its programmed conditions. |
| License or account error | The file was activated for another MT4 account number or account type. | Compare the logged-in number with the number sent to support. Do not send a password. |
| Wrong symbol or timeframe | The edition is attached to a chart other than EURJPY H1, EURJPY M15 or USDJPY M30. | Match the EA, pair and timeframe exactly and check any broker suffix. |
| Not enough money or margin | The requested order is too large for the available free margin or other positions already use it. | Reduce exposure, review all open trades and never use higher leverage as a substitute for risk control. |
| Results differ from monitoring | Broker feed, spread, execution, deposits, start date, settings or account conditions differ. | Compare like with like and expect some variation; do not force entries to reproduce another account. |
| MT4 stopped after a restart | AutoTrading, chart templates, login or VPS startup did not restore correctly. | Verify the account connection, EA status, charts and logs after every terminal or VPS restart. |
| Duplicate or conflicting trades | The same EA or another strategy may be attached to the same pair in several charts or terminals. | List every active chart and terminal. Keep one controlled EA instance per pair unless the configuration was intentionally designed otherwise. |
| Orders are rejected | Market is closed, volume is invalid, stops are too close, trading is restricted or execution failed. | Read the exact error code in Experts/Journal and confirm broker symbol specifications before changing the EA. |
| FX Blue chart does not display | Privacy protection, an extension or the monitoring provider may block the third-party frame. | Open the public FX Blue profile directly, test another browser with extensions disabled and do not treat a blocked widget as missing trading history. |
BEFORE GOING LIVE
Final launch checklist
Complete the list after every new installation, account change, broker migration or VPS rebuild.
- The MT4 account number matches the licensed file.
- The selected FXCityPro edition matches the chart pair.
- The chart timeframe is H1, M15 or M30 as required.
- The broker symbol and any suffix are recognized.
- AutoTrading and live-trading permission are enabled.
- The EA has been observed running on a demo account.
- Lot size and combined exposure fit the account risk limit.
- Free margin remains sufficient under adverse movement.
- Experts and Journal contain no unresolved errors.
- MT4 and the VPS remain online and reconnect correctly.
Change one variable at a time
If a problem appears, save the log message and a screenshot, then change only the item connected to that error. Multiple simultaneous changes make it difficult to identify the real cause.
FREQUENTLY ASKED QUESTIONS
Multiple-EA setup FAQ
Can I run all three FXCityPro EAs on one account?
It may be technically possible, but the account carries their combined exposure. Use separate MT4 installations, test the full portfolio on demo and size risk at account level.
Do separate terminals remove EURJPY overlap?
No. They isolate files and logs, not market exposure. Alpha X and FXCityPro_EUR can still hold related EURJPY risk on the same account.
Should I change Magic Numbers myself?
Use the supplied settings and documentation. Change a Magic Number only when the input is documented and you understand every active instance; otherwise contact support.
Is Auto Lot safer than a fixed lot?
Not automatically. Auto Lot changes size with account values, while a fixed lot is easier to audit. Safety depends on the total portfolio exposure and the loss you can accept.
Does a separate terminal require a separate account?
No. Several terminals can connect to the same account, subject to broker rules. However, true balance and margin separation requires separate accounts and compatible licenses.
What must I check after a VPS restart?
Confirm that every terminal opened, logged into the intended account, restored the correct chart, enabled AutoTrading and shows no error in Experts or Journal.
Can the MT4 mobile app run the EA?
No. Mobile MT4 can monitor the account, but the EA runs in a desktop MT4 terminal or Windows VPS.
NEXT STEP
Build the terminal map before enabling AutoTrading
Write down the EA, account, terminal folder, chart, timeframe, sizing mode and Magic Number for every instance. Then test the complete combination on demo and review total exposure from the account level.
