eSignal beginner needs a bit of help

[Easedale]

Hi all. I'm a long-time programmer who's new to eSignal.

I'm writing a small C# program for an eSignal customer. I'm wondering what eSignal interface is best to use.

All I need are realtime quotes: trade price, trade quantity, bid, bid quantity, ask, ask quantity, timestamp.

My app will run side-by-side with another app that the customer is already using. This other app, I'm told, is using the eSignal Control interface.

So I'm wondering if my app also must use the Control interface, or can it use the (seemingly simpler) Desktop interface?

Are there any extra fees involved in using the Desktop interface?

Many thanks for any help!

Your only option is the Desktop API and either the XMLGetBasicQuote() or GetTimeAndSales() functions. There is a one time cost of $195 and an additional $20/month to your eSignal subscription.

Thanks Robi. I'll go over this with the customer.
