It is recommended to use SymbolInfoTick() if the function is used for getting information about the last tick.
It may well be that not a single quote has appeared yet since the terminal is connected to a trading account. In such a case, the requested value will be indefinite.
In most cases, it is enough to use SymbolInfoTick() function allowing a user to receive the values of Ask, Bid, Last,
Volume and the time of the last tick's arrival during a single call.
