The NumberOfOrders() function.

This function returns the number of orders and functionally completely overrides ExistOrders(). To replace the ExistOrders() function with the NumberOfOrders() function, it is necessary and sufficient to check the return value so that it is greater than zero. You can limit the list of orders to be checked using the function parameters:

sy - Name of instrument. If this parameter is given, the function will only check the orders of the specified instrument. NULL means current instrument, and "" (by default) means any instrument.
op - Type of pending order. Valid values: OP_BUYLIMIT, OP_BUYSTOP, OP_SELLLIMIT, OP_SELLSTOP or -1. The default value of -1 means any order.
mn - Order identifier (MagicNumber). Default value -1 means any MagicNumber.

The ClosePosBySelect() function.

Closes one pre-selected position. This function is rather auxiliary, because it is called from several other functions, which help to select positions to close by some conditions.
