Writing a GUI in C# part 2

Also have a look at www.opentick.com - no web service but their API (support multiple languages) is very straight forward - it might even use REST internally - haven't investigated.

It's now free excluding exchange fees. I haven't used enough to determine quality of data issues yet but I'm sure others on ET have.

Indeed they do ... its fricking awesome!!!

the MAJOR draw-back is it only provides prices on orders they fill...
So, at times you don't know what have the stocks are trading at...

I have fifteen threads running, grabbing 100 at a time (max per request). Store in a DB .. query em against historical stats ...

You need to apply for a token ... Its Free!

Thank you! I needed exactly this for something I was working on last weekend. My observational skills must really suck, because I was looking at this exact page then, and somehow didn't see the "XML & Web Services" text there on the left :mad:

Thank´s for all the useful answers I got!. I am now able to connect to TWS, via a control supplied by IB. Visual Studio lets me
see a whole list of methods.

As a my next step I attempt to call the mehod 'reqMktData()
Unfortunately I don't know what values to put in the parameter list. Are there any descriptions, other than general things such as int, string etc.

It sounds like you need to take a look at the IB API documentation. You can find it here:

http://www.interactivebrokers.com/php/webhelp/webhelp.htm#Interoperability/DDE_Configure_TWS.htm

Click Application Program Interface -> ActiveX. To see the documentation of the methods and the events click on the ActiveX Methods or ActiveX Events menu item.

Have you used it ? I had a look at their support message board, and there seems to be some issues with historical data. As it is a new service, such things are to be expected, but it would be nice to know how robust it is at this stage.
 
Basic Question:
Why would anybody write a GUI in C# (or any other programming language for that matter)?

If you want to develop a GUI, you should first acquaint yourself with GUI frameworks available for your platform(s) and language(s) of preference.

Writing a GUI in any language puts you back into the stone-age.

FWIW, after a LONG experience with lots of stuff, I settled for the Qt framework (Trolltech). It helped me tremenously in moving my apps from M$ into linux.

Qt runs on windoz like on linux/unix. You can program in C/C++, Python and Ruby.
On top it's free for personal use.

Should have toyed with it a bit before giving it rave reviews.
I'm looking for a getLastTick ... (price,volume,time)... but the only thing resembling that is the HistData.

I'll see what I can do and update. The only thing I need is
RealTime Quotes for many tickers, not sure if that involves open/closing streams and requestings exchanges serparetely. That sounds like alot of overhead.

As for no-nonsenses question about Why? Well, perhaps we are geeks and enjoy doing it. For me, I built my own database, my "Gui" simply gives me pretty views into it. I use other apps for live charting and stuff.

Im new to the trading world, but I didn't notice any platforms providing direct SQL ability into records across multiple tables.
