CopyStar MT4

CopyStar MT4

CopyStar – File-based Trade Copier (MT5 Master/Slave, MT4-compatible)

Short description
CopyStar mirrors changes to your open net positions from the master to any slaves – quickly, robustly, and without network configuration. Communication runs via common files (shared file folder), enabling CopyStar to support MT5↔MT5, MT5→MT4, MT4→MT4, and MT4→MT5. Supports symbol mapping, lot multiplication, optional SL/TP copying, magic/comment filters, and a clear chart status display including heartbeat.

Highlights

• ? Delta mirroring: copies changes in net lots per symbol/direction (BUY/SELL).

• ? Zero-config networking: file-based via Common Files; no sockets/ports.

• ? Symbol mapping & LotMultiplier for broker symbol differences and risk scaling.

• ? Robust execution: retries, filling fallback (IOC→FOK→RETURN), slippage control.

• ? Filters: magic filter, comment substring, optional manual trades (Magic=0).

• ? Chart overlay with heartbeat traffic light (Green/Orange/Red).

• ? Groups: one master can broadcast to multiple SlaveGroups.

How it works

• Master aggregates BUY/SELL net lots per symbol. On changes, it writes delta signals to TradeCopierSignals_<Group>.txt and sends heartbeats to TradeCopierHB_<Group>.txt .

• Slave reads a chosen Group, applies SymbolMappings and LotMultiplier, executes orders with retries/fallbacks, and cleans up signals after success. Heartbeat age drives the overlay colour.

Input Parameters

COMMON_SETTINGS

• MasterMode (bool, default: true) – Master sends / Slave receives.

• CopySLTP (bool, false) – Copy SL/TP from the master. Must be set to true on both the master and slave for SL/TP to be copied!

• SymbolMappings (string, “NAS100=US100”) – MasterSymbol=SlaveSymbol, comma-separated.

  
  

MASTER_SETTINGS (master only)

• MasterMagicNumber – Magic for filtering.

• MasterFilterByMagic (true/false) – true=Only positions with this magic.

• MasterCopyManualTrades (true/false) – true=Include manual trades (Magic=0).

• MasterCommentFilter (string, "" ) – Comment substring; empty = ignore.

• SlaveGroups (string, "Group1") – Comma-separated target groups (e.g., Group1,Group2...). The master can serve multiple target groups!

SLAVE_SETTINGS (slave only)

• SlaveMagicNumber – Magic used by the slave.

• SlaveGroup (string, "Group1") – Slave belongs to exactly one group.

• LotMultiplier – Volume scaling before lot step rounding.

• Slippage – Max price deviation in points (internally min 50).

• MaxRetries – Retries for file/order access.

• FileWaitTime – Wait in ms between file retries.

• PollIntervalMs – Polling interval in ms for signals/status.

• SlaveClearSignalsOnInit (bool, true) – Clear old signals on start.

STATUS_SETTINGS → Chart / Heartbeat

• ShowCommStatus – Chart overlay.

• StatusCorner/StatusX/StatusY – Overlay placement.

• HeartbeatIntervalSec – Master heartbeat interval.

• HeartbeatTimeoutSec – Slave OK/Warn/Bad thresholds.

• StatusOK / StatusWarn / StatusBad – Colours (Lime/Orange/Red).

Requirements & Notes

• Platform: MT5 (MT4 reception requires a compatible MT4 reader).

• Permission: Enable access to Common Files.

• Symbols: Must be tradable/visible in the slave (Market Watch).

• Volume: Slave normalises to SYMBOL_VOLUME_MIN/MAX/STEP (rounds down to step).

• Terminals must be operated on the same VPS!

Limitations

• Market positions only (no pending orders).

• SL/TP only if present on the master at the time of the signal and CopySLTP=true on master & slave.

• Different contract specs require proper SymbolMappings.
