1. Overview

The ThoresDecimus Signal Receiver EA is an automated trading Expert Advisor (EA) for MetaTrader 4 (MT4) that connects to the ThoresDecimus trading platform to receive and execute trading signals automatically.

The EA polls the server every 60 seconds (configurable) to check for new trading signals. When a signal is received, it automatically opens positions according to the signal parameters and manages them using a sophisticated pyramiding strategy.

2. How It Works

2.1 Signal Reception

The EA connects to the ThoresDecimus platform server and polls for signals every minute. When you send a signal from your dashboard, the EA receives it and displays the information on the chart.

2.2 Trading Process

1. Signal Received: EA receives signal with pair, direction (LONG/SHORT), TP, entry price, and lot size.
2. Position Check: EA checks if any positions already exist for that pair. If yes, signal is ignored.
3. First Position: Opens first position at current market price with the specified lot size.
4. TP Calculation: First position's TP is calculated from the signal's entry price (not actual open price).
5. Pyramiding: If price moves 100 points in losing direction, opens additional position with increased lot size.
6. Auto-Close: When ANY position reaches its TP, ALL positions are closed automatically.

2.3 Lot Size Scaling

Additional positions use a progressive lot size formula:

Example: If TP = 200 points and previous lot = 0.01:

• Multiplier = 1.02 + (100 / 300) = 1.353
• New Lot = 0.01 × 1.353 = 0.0135 (normalized to 0.01 or 0.02)

4.1 EA Input Parameters

When you attach the EA to a chart, you'll see these input parameters:

Parameter	Default Value	Description
RailwayURL	https://nina-production-097d.up.railway.app	The server URL (usually doesn't need to be changed)
AccountNumber	(empty - REQUIRED)	Your MT4 account number. MUST be set! This links your EA to your platform account.
RequestInterval	60	How often (in seconds) the EA polls the server for signals. Default is 60 seconds (1 minute).

4.2 Finding Your Account Number

To find your MT4 account number:

1. In MT4, look at the bottom right corner of the terminal
2. Your account number is displayed there (e.g., "12345678")
3. Copy this number and paste it into the EA's AccountNumber input field

5. Trading Logic Explained

5.1 First Position

• Opens immediately when signal is received (if no positions exist for that pair)
• Opens at current market price (Ask for BUY, Bid for SELL)
• Uses the lot size specified in the signal
• TP is calculated from the signal's entry price (not the actual open price):
  • BUY: TP = Signal Entry Price + (TP points × Point Value)
  • SELL: TP = Signal Entry Price - (TP points × Point Value)

5.2 Additional Positions (Pyramiding)

• Opens when price moves 100 points in the losing direction from the last opened position
• Opens at current market price
• Lot size increases using the formula: Previous Lot × (1.02 + (100/(100+TP)))
• TP is calculated from the actual open price of that position:
  • BUY: TP = Open Price + (TP points × Point Value)
  • SELL: TP = Open Price - (TP points × Point Value)
• This process continues as long as price keeps moving against you (every 100 points)

5.3 Position Closing

• The EA monitors ALL positions every tick
• When ANY position reaches its TP, ALL positions are closed immediately
• After closing, the EA resets and waits for the next signal
• An alert will appear: "All positions closed! Ready for next signal."

5.4 Safety Features

• Position Check: If positions already exist for a pair, new signals are ignored
• Symbol Identification: Only trades positions with "ThoresDecimus Signal" comment
• Point Value Detection: Automatically handles different currency pair types (standard, JPY, Gold)

6. Troubleshooting

6.1 EA Not Connecting

6.2 No Signals Received

• Check that your Account Number is correctly set in EA inputs
• Verify you've connected to EA from the platform dashboard
• Check the EA logs in MT4 (View → Terminal → Experts tab) for error messages
• Ensure you have an active signal credit and have sent a signal from the dashboard

6.3 Positions Not Opening

• Check that "Allow automated trading" is enabled in MT4 options
• Verify your broker allows automated trading
• Check account balance and margin requirements
• Look for error messages in the EA logs

6.4 Chart Display

The EA displays two labels on the chart:

• Top label (white): "Last interrogation of the server: [timestamp]" - Updates every poll
• Bottom label (green): Last received signal details - Shows pair, direction, TP, price, odds, and lot size

If you don't see these labels, check that the EA is running (smiley face in top right of chart).
