# GMRFX Copytrade Local & Lan
> **Copy-Trade Master/Slave — One EA, File-Based Sync, Zero Network Config.**
> Copy trades between MT5 terminals on the same PC, across your local network, or over the internet — using nothing but a shared folder.

## What Is This?
**GMRFX Copytrade Local & Lan** is a single Expert Advisor that handles both **Master** (sender) and **Slave** (receiver) roles for copy trading. Pick your mode from a dropdown — done.
Unlike socket-based copiers that require IP addresses, port forwarding, and firewall rules, this EA uses a simple `.csv` file as its communication bridge. Your operating system handles the networking. You just point both EAs to the same folder.
### Where It Works
| Setup | Sync Method | Delay |
|---|---|---|
| **Same PC, multiple MT5 terminals** | Built-in (Common\Files\) | Instant |
| **2 PCs, same LAN** | Syncthing (free, P2P) or Windows SMB share | 0.5–2 sec |
| **2 PCs, different locations (internet)** | Syncthing, Dropbox, Google Drive, OneDrive | 2–5 sec |
| **PC to VPS** | Any cloud sync tool | 2–5 sec |

## Key Features
### One EA, Two Modes
No more juggling `Master_EA.ex5` and `Slave_EA.ex5`. A single file, a single parameter, instant mode switch. Version updates: one file.
### File-Based Communication
The Master writes position snapshots to `state.csv`. The Slave reads and reconciles. No sockets. No DLLs. No IP configuration. No port forwarding.
### Atomic Writes
Master writes to `.tmp` first, then renames to `.csv`. The Slave always reads a complete, uncorrupted file — even during concurrent access.
### Cross-PC Ready
`InpSyncFolder` can point to any folder — local, network share, or a cloud-synced directory. Use Syncthing (free, open-source, P2P), Dropbox, Google Drive, or OneDrive to bridge computers anywhere in the world.
### Smart Slave Logic
- **Anti-Reopen** — remembers positions you closed manually. Won't reopen them.
- **Age Gate** — only copies positions opened within N seconds. Filters stale signals.
- **Reverse Copy** — invert direction (Buy ↔ Sell). SL and TP swapped too.
- **Volume Control** — ratio mode (0.5x, 2x Master lot) or fixed lot.
- **Symbol Filter** — comma-separated list. Empty = all symbols.
- **Suffix Support** — handles broker symbol differences (EURUSD → EURUSD.r).
- **SL/TP Copy** — optionally copy Stop Loss and Take Profit from Master.
- **Spread Limit** — skip trades when spread exceeds your threshold.
- **Offline Detection** — detects Master shutdown. Optionally auto-close all Slave positions.
- **Bilingual Logs** — English or Bahasa Indonesia, selectable in parameters.
### Lightweight & Pure MQL5
No external DLLs. No custom indicators. No web requests. Runs entirely in `OnTimer()`. Minimal CPU and memory footprint.

## Why File-Based Sync?
| Approach | Problems |
|---|---|
| **Socket / TCP** | Complex IP config, port forwarding, firewall rules, often blocked by VPS providers |
| **DLL-based** | Security warnings on MT5, platform-dependent, fragile |
| **Web server / API** | Requires hosting, latency, subscription costs |
| **File-based (this EA)** | Zero network config. OS handles sync. Works on any setup. Free. |
**The folder is the protocol.** Your OS (or Syncthing/Dropbox) already knows how to move files between computers reliably. This EA just reads and writes CSV — and lets the OS do the heavy lifting.

## How It Works
```
PC MASTER PC SLAVE
┌──────────────────────┐ ┌──────────────────────┐
│ MT5 + Master EA │ │ MT5 + Slave EA │
│ │ write │ │
│ OnTimer() every N ms │──────────────│ OnTimer() every N ms │
│ -> write state.csv │ Syncthing │ -> read state.csv │

└──────── SyncFolder ────────────────┘
(Common\Files\CopyTrade\)
```
1. **Master EA** writes current positions to `state.csv` (via `.tmp` atomic write) every `InpRefreshMs` milliseconds.
2. **Folder sync** (Syncthing, Dropbox, etc.) copies the file to the Slave PC.
3. **Slave EA** reads `state.csv`, matches positions by unique ID, opens/modifies/closes trades to mirror the Master.

## Quick Start
### Same PC
1. Attach EA to Terminal A chart → Mode = **Master** → `InpChannel = "default"` → OK
2. Attach EA to Terminal B chart → Mode = **Slave** → `InpChannel = "default"` → OK
3. Done. Instant copy.
### Different PCs (via Syncthing)
2. Share `Common\Files\CopyTrade\` folder between them.
3. Both EAs: `InpSyncFolder = "CopyTrade"` (default).
4. Done. ~1-2 sec delay on LAN.
