dxFeed .Net API 5.9.0

• [Samples] Added the ability to connect with token in a dxf_events_sample

• Added the ability to override the type of data the application subscribes to

  • Added EventSubscriptionFlag enum with possible values:
    • Default that used for default dubscription behaviour
    • ForceTicker that used to force subscription to ticker data
    • ForceStream that used to force subscription to stream data
    • ForceHistory that used to force subscription to history data
  • Added the new NativeSubscription constructors and NativeConnection.CreateSubscription methods with additional parameter eventSubscriptionFlags.
  • [Samples] Added an additional command line parameter "[-s <subscr_data>]" to dxf_client (to describe how to use the new function with flags).
    This parameter accepts the next values:
    • 'TICKER' or 'ticker' to force subscription to ticker data
    • 'STREAM' or 'stream' to force subscription to stream data
    • 'HISTORY' or 'history' to force subscription to history data

• Added the Tick field to non ETH Trades.
  The Tick field Returns Trend indicator – in which direction price is moving. The values are: Up (Tick = 1), Down (Tick = 2), and Undefined (Tick = 0).
  The Tick field should be used if IDxTradeBase.TickDirection is Undefined

• Fixed the Direction enum.
  Now Down = 1 and ZeroDown = 2

• Added the candle price level attribute support. The candle price level (pl) defines additional axis to split candles within particular price corridor in addition
  to candle period attribute with the default value Double.NaN.
  So a one-minute candles of "AAPL" with price level 0.1 shall be specified with "AAPL{=m,pl=0.1}".

  • Added the CandlePriceLevel attribute class
  • Added the PriceLevel field to CandleSymbol class
  • Added additional utility methods to CandleSymbolAttributes:
    • The static constructor method PriceLevel.NewPriceLevel to construct PriceLevel from double precision floating point value
    • The static constructor method PriceLevel.NewPriceLevel to construct PriceLevel by string parsing

  Example: dxf_client demo.dxfeed.com:7300 Candle AAPL{=m,pl=0.1} 2020-01-01

• Added ability to retrieve regional TnS. Now API backend (C-API) subsribes to both composite and regional TimeAndSale events.
  Sometimes server may sent equal composite and regional TnS which differ by suffix only (for example: TimeAndSale and TimeAndSale&K).
  So the Scope field was added with possible values: Composite and Regional to IDxTimeAndSale, NativeTimeAndSale. Same field was added for
  IDxSummary and NativeSummary events.
  Please, use the Scope field to filter out duplicates.
