How do I check an account under investor mode using an EA?

Hi, is there any idea how to check an account under investor mode / trader mode using a function in MQL4?

I have used IsTradeAllowed but it is actually used to check AutoTrading button.

Thanks.

if(!AccountInfoInteger(ACCOUNT_TRADE_ALLOWED))
      Comment("Trading is forbidden for the account ",AccountInfoInteger(ACCOUNT_LOGIN),
            ".\n Perhaps an investor password has been used to connect to the trading account.",
            "\n Check the terminal journal for the following entry:",
            "\n\'",AccountInfoInteger(ACCOUNT_LOGIN),"\': trading has been disabled - investor mode.");

It’s working. Thank you
