* Fix the bug and add unit tests
- The bug was raised by different conditions.
First, the tick created in tick generator for Open Interest was not of type Open Interest.
Second, TickAggregator.cs was made to use daily resolution for OpenInterest always.
Third, the RandomValueGenerator, generated a random friday as expiration date for the option created but this one needed first two underlying data points, so if the expiration date was before the start date plus 3 days, RandomDataGenerator just generated OpenInterest data for the option.
* Add docs
This side steps the issue reported in #2840 by removing the desire to pass
zero for the maximum deviation. The previous issue was that we were leaning
on the trade ticks to produce the series variation and then trying to fit
quote ticks around a previously generated trade tick. This solution permits
both quote and trade ticks to produce variations and prevents the generator
from emitting both at the same time step.
A new parameter, --quote-trade-ratio, determines the relative density of each.
For example, a quote trade ratio of 1 means equal trade and quote ticks, whereas
a value of 2 means twice as many quote ticks as trade ticks.
This change also removes special treatment regarding the downsizing of the
requested deviation for quote ticks. If the consumer wants to limit the
deviation of quote ticks than the consumer can make that decision, but the
random value generator should simply follow instructions like a good little
boy.
Fixes#2840
The existing IdentityDataConsolidator consumes all ticks, completely ignoring
the tick type. I doubt this is ever the desired behavior, but given my
reluctance to break existing regression and unit tests as well as perhaps
user algorithms, I've added a layer on top to provide the proper filtering.
Removed the stub type which mirrored the TickAggregator and also expanded
the TickAggregator implementations to provide full coverage of the possible
ticktype/resolution cases: OpenInterestTickAggregator and IdentityTickAggregator
