When requesting historical data, the first time I make the call, the data looks good. But if I make a second request, I am getting duplicated bars: Below is the output from my program. you can see in the second request, the duplicated bars I am receiving.
I am making the request like this:
oecapi.RequestTicks(contract, begindate.ToUniversalTime(), DateTime.UtcNow);

I am cancelling the historical request before starting the 2nd one by calling:
oecapi.CancelSubscription(subscription);

is there anything else I need to be doing?

Thanks,
Eric Nissan

After the first request I see:

Are you sure you didn't hook to the event twice?

I just double checked, I did not. and the odd thing is, if I request a 3rd time, it still doubles the data, but doesn't triple it.

Can you reproduce it in OEC Sample?
