tastyware/tastytrade:v9.9

[Graeme22]

What's Changed

• Added missing: used_derivative_buying_power data field by @JBlohm in Added missing: used_derivative_buying_power data field #210. This allows you to calculate buying power usage in the same way Tasty does it. This can be accessed as AccountBalance.used_derivative_buying_power and AccountBalanceSnapshot.used_derivative_buying_power.
• add streamer refresh interval by @Graeme22 in add streamer refresh interval #212, many thanks to @bonkzwonil for opening aggregationPeriod not configurable #211!
  Previously, the dubiously named "acceptAggregationPeriod" parameter to newly created DXLink channels was hardcoded to 10 seconds. This resulted in events like Quote being updated only once every 10 seconds, a far cry from live streaming! Now this value is adjustable as a new parameter to DXLinkStreamer, but it defaults to 0.1 which should be close to live for most use cases.
  Example usage:

streamer = await DXLinkStreamer(session, refresh_interval=5)

Since the new default is 0.1, most users should immediately see a benefit without making any changes at all.

New Contributors

• @JBlohm made their first contribution in Added missing: used_derivative_buying_power data field #210
