I think you need a global variable (global within the MetaTrader that can be read from all EAs) and then a button that switches the variable on and off.

void SwitchTradingOn() {
  GlobalVariableSet("TradingOn",1);
}

void SwitchTradingOff() {
  GlobalVariableSet("TradingOn",0);
}

bool IsTradingAllowed() {
  return GlobalVariableGet("TradingOn")==1;
}
