[BUG]: Receiving multiple "minute bar" updates for the same minute

Is there an existing issue for this?

• I have searched the existing issues

Current Behavior

I’m not 100% sure if this is a bug or not, but when subscribing to “BTCUSD” with the CryptoStreamingClient.SubscribeMinuteBarAsync(...) method, I’m getting minute bar updates just fine, but periodically I get multiple updates for the same minute in very quick succession (see screenshot below).

(left timestamp is the bar timestamp, and the right timestamp is DateTime.UtcNow)

I do get different data per event trigger (the latest bar information). Is this expected behavior? This is effecting my calculations and how my code reacts to price changes. Maybe I need to be able to handle this kind of behavior?

Expected Behavior

I would expect the minute bar subscription to only trigger 1 event every minute.

Steps To Reproduce

var dataSubscription = await CryptoStreamingClient.SubscribeMinuteBarAsync("BTCUSD");
dataSubscription.Received += bar => { /* ... */ };

Environment

- SDK Version: 6.0.2-alpha2
- OS (version, bitness): Windows 10 x64
- .NET SDK (version): 6.0

Anything else?

@polymorphicshade Thanks for the prompt answer. I’ll just add a small correction: if @PlayCreatively want’s to specify an exchange(s) for the streaming crypto data the WithExchanges method should be called for the AlpacaCryptoStreamingClientConfiguration class instance.

BTW, the underlying REST API for historical crypto data doesn’t support per-exchange bars/trades/quotes anymore so WithExchanges methods for historical data requests will not have any effect in SDK version 6.1.0 and above.

@PlayCreatively use the WithExchanges() extension method: new HistoricalCryptoBarsRequest(...).WithExchanges(...);
