Build MT4 Expert Advisor that Trades Based on Telegram Signals

I need an Expert Advisor (EA) for MT4 that automatically executes and close trades based on signals received from a Telegram channel. The EA must read Telegram messages, parse specific fields, determine BUY/SELL direction, and open trades according to predefined rules.

Telegram signal is received from specific TELEGRAM_TOKEN  and CHAT_ID

Signal Parsing Requirements, I will provide signal samples.

Trade Execution                     

When a valid signal arrives:

• Determine BUY/SELL and close position from pattern.
• Open market order at nearest available MARKET PRICE
• Lot size (default 0.10)
• Avoid duplicate trades for the same symbol and same signal.
• Option to close previous trade when new signal arrives.
• Input parameter: Max_Open_Positions
• EA must NOT open new trades if this limit is reached.
• EA working hours
• Auto‑close at specific time
• Custom comments

• AND message contains specific phrase
