Hi,

The following is excerpt from LIVE software connected to SIM server
Why is it suddenly returning 0 today?
It was all ok last friday.

m_Client.RequestTicks(Contract, Start, [End])

...
...
...

Private Sub m_Client_OnTicksReceived(ByVal Subscription As OEC.API.Subscription, ByVal Ticks As OEC.API.Ticks) Handles m_Client.OnTicksReceived
DataLength = Ticks.Prices.Length

For i = 0 To DataLength - 1
e.size = Ticks.Volumes(i) ' why is Ticks.Volumes(i) always 0???
next
end sub

Ticks.Volume is obsolete. You should use Ticks.Volume32 instead, because it uses a larger datatype that better represents the data.

That said, we will release a fix that restores Ticks.Volume data.

Typically we mark obsolete members with the [Obsolete] tag. That should make it clear in intellisense, documentation, and compiler warnings. But in this case Tick.Volume should have been marked but wasn't. Our apologies for the confusion.
