how to close an order using the api MT4-Manager-API without specifying the closing price?

Question

I am using the MT4-Manager-API Api, and I want to close trades at the current market price, without having to specify it.

So far I have been able to close a previously opened trade but specifying the closing price as follows:

c++ code

TradeTransInfo  info = { 0 };
info.type = TT_BR_ORDER_CLOSE;
info.order = 98492174;
info.price = 1.30263; // I don't want to have to specify the price. 
info.volume = 1;
ExtManager->TradeTransaction(&info);

I also don't want to switch to pumping mode.

EDIT

The main reason for not wanting to specify the closing price is because I can't find a way to obtain it by making an API call, without switching to pumping mode.

By getting the current price of the symbol, I can then solve my problem and use the code shown.
