How to Use No Limit Algo Copy Trade EA on MT4 and MT5

How to Use No Limit Algo Copy Trade EA on MT4 and MT5

No Limit Algo Copy Trade allows members to receive trading positions from a master account directly on MetaTrader 4 or MetaTrader 5. The system automatically synchronizes new positions, supported symbols, lot sizes, Stop Loss, Take Profit, and position closures according to the selected settings.

Main Features

  • Supports MetaTrader 4 and MetaTrader 5
  • Compatible with different brokers
  • Automatic broker symbol detection
  • Supports broker suffixes such as EURUSDc, GBPUSDpro, or XAUUSDm
  • Selectable Forex, XAUUSD, crypto, and synthetic symbols
  • Adjustable fixed lot or lot multiplier
  • Optional balance-ratio lot calculation
  • Buy and Sell position filters
  • Automatic SL and TP synchronization
  • Stale signal and heartbeat protection
  • Maximum spread filter
  • Maximum positions and total-lot limits
  • Online account license verification
  • Lightweight monitoring dashboard

Requirements

Before installation, members need:

  • An active MT4 or MT5 trading account
  • The correct Copy Trade EA version for their platform
  • An active No Limit Algo membership
  • A registered MetaTrader account number
  • Stable internet or VPS connection
  • Algorithmic or automated trading enabled

The member’s MT4 or MT5 account does not need to use the same broker as the master account.

Download the Correct EA

Use the EA version matching your trading platform:

  • MT4 EA files use the .ex4 extension.
  • MT5 EA files use the .ex5 extension.

An MT4 EA cannot run on MT5, and an MT5 EA cannot run on MT4.

Download the official member package only from:

https://nolimitalgo.com

Installing the EA on MT4

  1. Open MetaTrader 4.
  2. Select File → Open Data Folder.
  3. Open the MQL4 → Experts folder.
  4. Place the No Limit Algo Copy Trade .ex4 file inside it.
  5. Restart MT4 or refresh the Navigator panel.
  6. Open Navigator → Expert Advisors.
  7. Drag the Copy Trade EA onto any active chart.
  8. Enable Allow live trading.
  9. Activate the AutoTrading button.

Installing the EA on MT5

  1. Open MetaTrader 5.
  2. Select File → Open Data Folder.
  3. Open the MQL5 → Experts folder.
  4. Place the No Limit Algo Copy Trade .ex5 file inside it.
  5. Restart MT5 or refresh the Navigator panel.
  6. Open Navigator → Expert Advisors.
  7. Drag the Copy Trade EA onto any active chart.
  8. Enable Allow Algo Trading.
  9. Activate the Algo Trading button.

Only one chart is normally required for each Copy Trade EA or signal category.

Enabling WebRequest

The web-based Copy Trade system requires MetaTrader to communicate with the No Limit Algo server.

On MT4 or MT5

  1. Open Tools → Options.
  2. Select the Expert Advisors tab.
  3. Enable Allow algorithmic trading.
  4. Enable Allow WebRequest for listed URL.
  5. Add these trusted domains:
https://nolimitalgo.com/
https://memberea.my.id/
  1. Click OK.
  2. Remove and reattach the EA if necessary.

The complete PHP endpoint does not need to be entered. Adding the main domain is sufficient.

Activating the Online License

The EA reads the MetaTrader account number automatically. Members do not need to enter a username.

The license will work when:

  • The MetaTrader account number is registered.
  • Membership status is active.
  • The license has not expired.
  • The correct platform, MT4 or MT5, is selected during registration.
  • WebRequest access is enabled.

If the dashboard displays ONLINE LICENSE BLOCKED, verify the registered account number, license status, internet connection, and allowed WebRequest domains.

Selecting Trading Symbols

All symbol selections may initially be set to false. Enable only the instruments you want to copy.

Example:

Copy_EURUSD = true
Copy_GBPUSD = true
Copy_XAUUSD = false
Copy_BTCUSD = false

The EA can map the master symbol to the corresponding broker symbol automatically. For example:

Master: GBPUSD
Copier: GBPUSDc

Only instruments available in the copier broker’s Market Watch can be traded.

Configuring the Lot Size

Fixed Lot

Enable UseFixedLot to use the same selected lot for every copied position.

UseFixedLot = true
FixedLot = 0.01

Lot Multiplier

Disable fixed lot and use a multiplier based on the master position:

UseFixedLot = false
LotMultiplier = 0.50

If the master trades 0.10 lot, a multiplier of 0.50 produces approximately 0.05 lot on the copier, subject to broker limits.

Balance-Ratio Lot

This option adjusts the copied lot according to the balance difference between the master and copier accounts. It should only be used after understanding its risk calculation.

For new members, a fixed lot of 0.01 is generally the simplest starting configuration.

Risk Protection

Members can configure:

  • Maximum copied positions
  • Maximum total copied lots
  • Maximum spread
  • Buy-only or Sell-only copying
  • Floating-loss protection
  • Symbol selection
  • Fixed or proportional lots
  • Stop Loss and Take Profit synchronization

These controls do not eliminate trading risk. They help restrict exposure according to the member’s account size.

Signal Freshness Protection

The EA includes heartbeat and stale-snapshot protection. It rejects old master data after an internet interruption or delayed server connection.

This helps prevent the copier from:

  • Opening a position that has already closed on the master
  • Copying an outdated entry at a significantly different price
  • Opening and immediately closing an expired master position
  • Replaying old trading history

Keep these protections enabled unless instructed otherwise by No Limit Algo support.

Running Multiple Copy Trade EAs

Multiple Copy Trade EAs can operate on one terminal when each uses:

  • A different signal category or channel
  • A different Magic Number
  • Separate chart placement
  • Correct symbol selections
  • Sufficient terminal and VPS resources

Avoid running duplicate copier EAs for the same signal channel because this may create duplicate positions.

Recommended Setup

For more reliable operation:

  • Use a VPS close to the broker’s server.
  • Maintain a stable internet connection.
  • Keep MetaTrader running continuously.
  • Disable computer sleep mode.
  • Do not change hidden server settings.
  • Start with the smallest lot.
  • Monitor margin level and total exposure.
  • Test on a demo account before using real funds.

Important Notice

Copy trading does not guarantee profit. Market movement, spread, slippage, broker execution, internet delays, leverage, and copier settings can cause results to differ from the master account.

Members remain responsible for selecting an appropriate lot size and monitoring their trading accounts.
