MQL4 developer to build a custom MT4 Expert Advisor based on a Koncorde-style indicator strategy.

Hello, I’m looking for an experienced MQL4 developer to build a custom MT4 Expert Advisor based on a Koncorde-style indicator strategy.

Here are the main requirements:

🔹 General Overview

• The EA must be a master EA, running on a single chart and managing multiple currency pairs simultaneously
• No need to attach EA to each chart
• Must support a configurable list of symbols

🔹 Indicator Requirement

• Develop a custom Koncorde-style indicator (no source code provided)
• Focus only on:
  • Green line (main signal)
  • Red line (average)
• The EA will use iCustom to read indicator values

🔹 Multi-Timeframe Logic

• W1 (Weekly): defines trend
  • If condition bullish → BUY only
  • If bearish → SELL only
  • On trend change → close all trades
• H1 (1 Hour): execution timeframe

🔹 Entry Conditions (H1)

• BUY:
  • When signal line crosses UP through level 40 (exact crossing)
• SELL:
  • When signal line crosses DOWN from above 80 (exact crossing)
• No trades if conditions are not freshly met

🔹 Exit Conditions (H1)

• BUY:
  • Close when signal crosses above 80
• SELL:
  • Close when signal crosses below 40

🔹 Trade Management

• Allow multiple positions (scaling) per pair
• Open new trade on every valid signal
• All trades follow weekly direction

🔹 Risk Management

• Max trades per pair (input)
• Max trades globally (input)
• Lot size / risk configurable

🔹 Multi-Pair System

• EA loops through all configured symbols
• Uses separate magic numbers per pair
• Manages trades independently per symbol

🔹 Other Requirements

• Clean and optimized code
• Proper error handling
• Backtest-compatible
• Ability to modify parameters via inputs
