Hello @daniel03 ,

Please see Tutorial: Monitor Positions in C# for more information- positions are communicated asynchronously.

You may see Add(s) after the initial Snapshot. You may, potentially, have Add(s) after Update(s). However, the set of Positions, should be fully communicated within a short period of time, so if you do not see any Adds for a bit of time, you have the current complete set.

Positions are a moving target, if Positions change in any way, monitoring will reflect the changes.

That document states "The total number of Positions held is communicated within very short period of time after Positions monitoring request is submitted." but I'm missing the part of the sample code that shows how to receive that number.

Hello @daniel03 ,

There is no method call to request and receive the number of positions.

The only option is to register interest, and to be notified of and process any change in positions.

At any point of time, the positions can change, resulting in callback triggered, there is never "a guaranteed static state" per design.

Hope this explanation helps
