How to check if tick is ASK or BID type (when using Tick chart with LAST type)

[ttodua]

as title says, when using i.e. 1-Tick chart, with 'LAST' as datatype, is there any way from indicator, to determine whether currentbar's (tick) marketDataType is ASK or BID ?
BarsPeriod.MarketDataType gives Last, which is not the goal in reality (because we should find out if it is either ask or bid). I know someone might suggest adding multiple AddDataSeries to solve the problem, but that is out of scope.

Hi, thanks for posting. MarketDataType.Last, MarketDataType.Bid, and MarketDataType.Ask are all different streams. Last ticks are completed trades and Bid/Ask may not be completed. If you want to see if a Last tick was a buy or sell, please use the example I have attached to this post.
