MT4 EA to Stop Opening New Trades (Allow Existing Trades Only)

🔹 Project Description

I need a very simple MT4 (MQL4) Expert Advisor to be used on a DEMO account.

Main Purpose:
When enabled, the EA must prevent opening any NEW trades, while allowing existing open trades to be managed and closed normally.

Required Behavior:

• Do NOT close any open trades.

• Do NOT modify TP or SL.

• Prevent opening of:

  • New initial trades

  • New trade cycles

• Existing trades must continue until they close naturally by TP/SL.

Important:

• This EA will work alongside another Grid/Martingale EA.

• The goal is to stop NEW entries only, not trade management.

• The EA must NOT cause fast open/close behavior.

Input Parameters:

• EnableBlock = true / false

  • true → block new trades

  • false → do nothing

• (Optional) Block only initial trades (TradeNumber = 00 or first trade in a cycle)

Notes:

• The EA runs on a DEMO account.

• Trades are copied from this account to a funded account using a trade copier.

• This solution must be safe for prop firm rules.

Goal:
To stop opening new trades before withdrawal while allowing all existing trades to finish naturally, so the funded account reaches zero open trades safely.
