Starts an asynchronous request for ticks.
Syntax

Public Function RequestTicks( _ ByVal cqg_ticks_request As CQGTicksRequest _ ) As CQGTicks |
Parameters
- cqg_ticks_request
Specifies the ticks request, which contains all the parameters as properties.
Notes:
Values provided for properties that are not required are ignored.
If values are not provided for properties that are required, an exception will be thrown.
Remarks
An exception will be thrown if an asynchronous request could not be made.
Otherwise, returns CQGTicks object, which doesn't contain any ticks yet and which status is rsInProgress.
Notes:
It is a good practice to cancel the request as soon as it becomes unnecessary. Such approach allows using memory resources more optimal.
Call RemoveTicks for request cancelling.
