Ben Davison	635ba1747c	removed not implemented exception from the dispose override in the TestableSymbolOrderBook implementation	2020-01-30 17:59:21 +00:00
Ben Davison	08d7022815	introduce a default empty ISymbolOrderBookEntry that is returned buy BestBid or BestAsk if called when the bid or ask lists are empty. This resolves a null reference exception seen during syncronization (specifically when connecting to Kraken). I have also introduced BestOffers which returns both bid and ask in the scope of one lock allowing the caller to be sure that nothing has changed between BestBid and BestAsk request.	2020-01-30 16:55:47 +00:00
