Common Settings
General EA configuration shared by both Master and Slave modes.

Mode (Mode)

Sets whether this terminal acts as the Master (sends trades) or Slave (receives and mirrors trades).

Fix Type (FixType)

Controls how the EA handles symbol naming differences between terminals:

• Auto Detect (AutoFix): Automatically deduces prefix/suffix.
• Manual Entry (ManualFix): Uses manually provided Prefix_ and Suffix_.

Operation Speed (Speed)

Determines how frequently the EA scans for trade updates:

• Normal (NormalSpeed) – Balanced operation.
• Fast (FastSpeed) – Quicker response but higher resource usage.
• Turbo (TurboSpeed) – Maximum speed for ultra-fast copying.
• Stable (StableSpeed) – Recommended stable pace for most scenarios.

Stabilising Delay for Stable  (Stablizing)

Master Settings
Settings specific to the terminal operating in Master mode (broadcasting trades).

Master ID (MasterID)

Unique name to identify this terminal as a master instance. Slave EAs will use this ID to find the trade data file.

Master Symbol Prefix (MPrefix_)

Use this if your broker applies a prefix to symbols (e.g., XEURUSD). Leave blank if not needed.

Master Symbol Suffix (MSuffix_)

Use this if your broker adds a suffix to symbols (e.g., XAUUSD.i). Leave blank if not needed.

Lot Size Settings
Configures how trade lot sizes are calculated and scaled on the slave side.

Auto Detect Initial Balance (InitialBalanceDetect)

Enable automatic detection of the first deposit on this account.

Initial Balance Set (InitialBalanceSet)

Minimum Lot Allowed (MinLotFixing)

The minimum volume allowed for any trade, even after rounding or risk calculations.

Maximum Lot Allowed (MaxLotFixing)

Examples: Allow/Disallow Configurations

Manual trades only for selected symbols:

• AllowSyms:  Gold.x,WS30

• AllowMNs:  0

EA with specific Magic Number, block unwanted symbols:

• AllowMNs:  897

• DisallowSyms:  WTI,USDJPY

Allow everything, but exclude based on comment:

• DisallowComms:  Slow EA

Block manual trades, allow specific EA:

Disallowed rules take priority if any conflicts arise.

Advanced Scenarios and Use Cases

Prop Firm Compatibility

• Use  SLType = ATRBased,  TPType = SLMultiplier for SL/TP enforcement.

• Set  DelayTolerance = 3–5 to bypass prop firm trade copy detection.

One-to-Many Broadcasting

• Configure one terminal as  Mode = Master, with many Slaves sharing the same  MasterID.

• Adjust each Slave's lot scaling settings individually.

Multi-Master to One Slave

• Run multiple Masters, each with a unique  MasterID.

• Filter trades on the Slave using  AllowMNs,  AllowComms, or  AllowSyms.

Manual Signal Amplifier

• Place manual trades on Master.

• On Slave:  AllowMNs = 0,  LotType = LotEquityRatio for auto-scaling.

Hedging via Reverse Mode

• On Slave, enable  CopyReverse = true.

• Useful for mirrored strategies or inverse hedging.
