Hey,

I am using the IQFeed provider.

How can I see in ticks history (180 ticks) if the last price is a bid price or a ask price?

Hi,

You can't. Wealth-Lab does not support bid/ask data. Furthermore, they are not required in our model. Here's how the process works in WL:

I am using IQFeed, is there a technique to display the Bid and Ask price on the ghost bar?

No, painting bid/ask on the ghost bar is not supported - only rendering its properties like OHLC. Rendering the Bars is ChartStyle's prerogative but bid/ask are properties of the Quote object which has no use in the context of the ChartStyle development.

Just a speculation: if only a data provider is specifically tailored to deliver bid/ask in say Bars.Tag property and again, a custom built ChartStyle would extract that data for rendering. Anticipating a potential question, neither our providers nor chart styles can be tweaked this way because the Bars.Tag is a property which is used in other scenarios and should remain as is.

Anyway, I cannot imagine why anyone would go that far to pursue such a cosmetic task.

You can get a Bid/Ask with a quote from the Trade Ticket.
Ctrl+T for the TT frame, type in a symbol and hit tab for the quote. You'll need to Authenticate first to see the quote.
