Ladder Building

[Grantay.]

Hi All,

I want to build a ladder to show more market depth than my current grid view allows.

In Marketbook using EX_ALL_OFFERS I can get the data I want for a particular market, but before I launch off and start building a container to display the data, I though I would ask what other developers have found the best method.

I figure a static pre-built DGV would work where data can be added where it matches - on the other hand showing the data on the fly may work with panels and so on.

Can anyone fill me in on their experiences?

Which UI framework are you using? WinForms? WPF/XAML?

I develop using WPF and would use a DataGrid to represent a ladder interface. I would bind the grid to a collection which represents each possible odds value.

There's obviously more to it than that, but without knowing how you're going about the development it's hard to provide detail.

I did mess around with ladders at first but, to be frank, you are just reinventing the wheel. If you want ladders then use Cymatic, it's free.

I use the API to create bots that have minimal GUI interfaces. For manual trading I use Cymatic.

When I did code up a ladder then I did as suggested, a static datagridview bound to its data source.

As I view all races for the day simultaneously and build a portfolio position then it's just not feasible to have a human interface at that point. Better to develop algorithms that do the work for you.
