PropBlaster Trade Copier for MT5 (Master → Slaves) – User Guide

The copier mirrors every trade of your master account to any number of slave accounts on the same PC. The slave terminals run invisibly in the background. The master EA also contains the PropBlaster Panel for trade planning, lot sizing and trade management.

Files: mt5/PropBlaster_Master.mq5, mt5/PropBlaster_Slave.mq5 (until PropBlaster 4.5: TradeCopier_Master / TradeCopier_Slave) and the scripts in copier/ (TradeCopier.ps1, TradeCopier_Setup.cmd, TradeCopier_Start.cmd, TradeCopier_Stop.cmd, TradeCopier_Status.cmd).

How it works

• Your MT5 installation stays as it is. You are logged in to the master account there as usual, and the master EA runs there.
• For each slave account, the setup creates a separate portable copy of the terminal (%LOCALAPPDATA%\TradeCopier\Slave_<Login>). This copy logs in automatically, starts minimized and runs the slave EA. You never need to touch these terminals.
• A watchdog – an invisible PowerShell script, or PropBlaster itself with the built-in engine – starts the slave terminals with Windows and restarts terminals that have crashed.
• Communication runs through a file in the shared folder Common\Files\TradeCopier. Master trades appear on the slaves after about 0.2–0.5 s.

What is copied

Setup (one time, about 10 minutes)

1. Double-click TradeCopier_Setup.cmd in the copier folder.
2. The setup finds your MT5 installation and asks for:
3. the account number of the master
4. per slave: account number, server name (exactly as in the MT5 login window), trading password, chart symbol (default: EURUSD)
5. The setup then automatically:
6. creates the terminal copies (about 150–300 MB per slave)
7. distributes the EAs and settings
8. copies the master EA into your installation
9. sets up autostart
10. In the main terminal: Navigator → Expert Advisors → Refresh → drag PropBlaster\PropBlaster_Master onto any chart, OK. InpMasterLogin can stay 0 – the EA then uses the account logged in when it starts (enter the number explicitly if you want to pin it). Because the master EA also contains the PropBlaster Panel, Algo Trading must be enabled in the main terminal ("Allow Algo Trading" checkbox and the Algo Trading button).
11. Confirm "Start slave terminals now" in the setup with y. Minimized MT5 windows appear in the taskbar, one per slave.
12. Check once: open a slave window. The top-left of the chart must show Status: OK – Master …. In the journal under "Experts", master and slave must show the same Common folder.
13. Test with a mini trade on a demo master.

PropBlaster Panel (in the master EA)

The master EA shows a panel in the top-left corner of the chart for planning, lot sizing and SL placement. It trades the symbol of the chart the master EA is attached to. If you change the chart's symbol, the copier simply keeps running.

1. Risk: the button toggles between % Balance, % Equity and Amount (account currency). Enter the value next to it.
2. SL pips: default stop-loss distance.
3. TP: the button toggles between
4. R:R: TP = R:R × SL distance, value in the field next to it
5. free: drag the TP line with the mouse
6. off: no TP
7. Order type: MARKET (immediate) or PENDING. For pending orders the panel picks limit or stop automatically, depending on where the entry line is relative to the current price.
8. Plan BUY / Plan SELL: entry (blue), SL (red) and TP (green) lines appear on the chart. Drag the SL (and for pending orders the entry) to the desired place, e.g. below the order block.
9. The panel shows the lot size, the risk in money and %, SL/TP in pips, the R:R and the order type live.
10. EXECUTE sends the order. CANCEL removes the lines.

Notes:

• The lot size is rounded down, so the risk never exceeds the configured value. If the risk is too small for the minimum lot, the panel blocks and shows a warning.
• The panel also blocks if the SL is on the wrong side, margin is insufficient, the SL is too close (broker minimum) or Algo Trading is disabled.
• Commission and swap are not included in the lot calculation.
• Pips: for 5- and 3-digit prices, 1 pip = 10 points; otherwise 1 pip = 1 point (e.g. gold: 1 pip = 0.01).
• Settings are remembered: the panel keeps risk, SL, R:R and modes, even after a symbol change or a restart.
• Panel trades get the comment MJ-Panel. They are copied to the slaves like all other trades.
• Hotkeys and OCO orders are not included.

Management section

Below the order section, the panel offers trade management (start values come from the EA inputs under "Management"; afterwards the panel remembers your entries):

• Auto-BE: when a position reaches X R profit, its SL is moved to entry + offset (pips). Applies to all positions of the master account that have an SL.
• Trailing: trails the SL at the set distance in pips. Trailing starts only once the SL is at break-even. Applies to all positions of the master account.
• BE now: moves the SL of all positions on the chart symbol to entry + offset, if the position is far enough in profit for that.
• Partial close: closes the set percentage of all positions on the chart symbol.

Management only acts while the terminal is logged in to the master account.

Auto journal

If the inputs under "Auto-Journal" are enabled, the master EA reports every opening and every full close of a master position to the PropBlaster Journal and takes chart screenshots (1m / 15m / 1H, optionally also at the close, with discreet entry/exit markers). The screenshots use the chart template set in InpShotTemplate (default Journal.tpl).

Operation

The slaves can also be controlled from the "Copier" tab of the PropBlaster Cockpit (see the Cockpit guide).

Built-in copier engine (beta)

Instead of the PowerShell script, PropBlaster itself can run the watchdog and manage the slaves. Switch it in PropBlaster under Settings → Trade copier → Copier engine:

• PowerShell script (classic) – default. TradeCopier.ps1 runs the watchdog; the Startup shortcut "TradeCopier Slaves" starts it with Windows.
• Built-in (beta) – PropBlaster runs the watchdog (it starts with Windows through PropBlaster's own autostart). The shortcut "TradeCopier Slaves" is moved out of the Startup folder (kept as %LOCALAPPDATA%\TradeCopier\TradeCopier Slaves.lnk.propblaster-bak) so the two never compete.

Both engines use the same folder, the same config.json, the same slave terminals and the same encrypted passwords – nothing has to be set up again, and you can switch back and forth at any time. Only one watchdog ever runs: if a PowerShell watchdog is still running when you switch to the built-in engine, it keeps that role until it ends (e.g. at the next Windows restart); then PropBlaster takes over.

With the built-in engine you can add slaves (account number, server name exactly as in the MT5 login window, trading password, chart symbol), change passwords, remove, start and stop slaves and change the master in the "Copier" tab – no console window needed. The very first setup (finding the MT5 installation, choosing the master) is still done once with TradeCopier_Setup.cmd.

Switching back: select "PowerShell script (classic)" and save. PropBlaster ends its watchdog (a slave that is just starting is finished first, up to 3 minutes), puts the Startup shortcut back and starts the PowerShell watchdog. If the shortcut is missing, run TradeCopier_Setup.cmd → [3] once; it recreates it.

The built-in engine needs PropBlaster to be running. If you close PropBlaster, running slave terminals keep running and copying, but crashed terminals are not restarted until PropBlaster runs again.

Safety behavior

• You log in to a different account in the main terminal: the master EA detects this and pauses. The slaves pause as well; nothing is closed or opened. Once you are back on the master, everything continues.
• Master positions opened during the pause that are older than 60 s when you switch back are not copied.
• Master terminal closed or PC in standby: same behavior – the slaves freeze. Open trades keep their own SL/TP.
• A slave EA trades only on a file from the configured master account, and never on the master account itself.
• Only one slave EA can run per slave terminal (lock against duplicate openings).
• Nothing is opened twice after a restart: already copied tickets are restored from the history of the last 7 days.
• A slave position that was closed or deleted individually is not reopened.
• Passwords are stored encrypted with Windows DPAPI in %LOCALAPPDATA%\TradeCopier\config.json. Only your Windows user on this PC can read them. The startup file containing the password (tc_start.ini in the slave folder) is deleted as soon as the slave EA has loaded, at the latest after about 3 minutes.

Settings (slave, in MQL5\Presets\PropBlaster_Slave.set of each slave terminal)

Requirements and limitations

• The PC must be running and you must be signed in, otherwise nothing is copied. Power options: no standby during trading hours. For continuous operation, a Windows VPS is better – but not the MetaQuotes VPS.
• RAM: about 200–400 MB per slave terminal.
• Designed for hedging accounts, same broker, same symbol names.
• Test with demo accounts first. With prop firms, check whether copiers are allowed.
• Each slave terminal installs broker updates by itself.

Troubleshooting

Renamed EAs (PropBlaster 4.6)

TradeCopier_Master / TradeCopier_Slave are now called PropBlaster_Master / PropBlaster_Slave and live in MQL5\Experts\PropBlaster\. Nothing else changed (same channel files in Common\Files\TradeCopier\, same inputs, same config).

Migration: - Master: the installer puts PropBlaster_Master.ex5 into Experts\PropBlaster. The old TradeCopier_Master keeps running on its chart until you swap it: remove it from the chart, then drag PropBlaster_Master onto the same chart and set the same inputs (or load a saved .set). Best on the weekend or without open positions. Two masters at the same time are prevented by the EA. - Slaves: nothing to do. On the next (re)start of a slave terminal, the copier (script or built-in engine) installs PropBlaster_Slave into the slave folder, writes PropBlaster_Slave.set and starts the terminal with it. If the new file is not available, the slave keeps running TradeCopier_Slave – it never starts without an EA. The old files stay where they are and can be deleted later. - The setup assistant shows a terminal that only has the old master as "older version – please update".
