I've been playing with some crypto trading simulations lately and have been using vvvv for prototyping most of the time. So far i have no problems using the old but gold HTTPGet (Network String) Nodes to recieve Public Data from Bittrex's API.
For Example Like This: https://drive.google.com/open?id=1bxvckQUycUKTaUz7oI9ll9rNUVGfDHLc
(who the fuck's decicion was it to exclude new users from adding attachments? i mean wtf guys, don't break my balls :P)
Now it would be time to Post back some stuff. I have some trouble configuring the Header in a way that it works with bittrex. I Have 3 problems
Header Format: How do i Format the Header in application/JSON Format within VL and how do i integrate the already placed (but still kind of hidden) field into the dataflow correctly.
Authetication: Is there a way to Hash API Keys, Secret, Nonces etc. together within VL like it is asked by bitrex: https://www.bittrex.com/Home/Api <-- Authentication
(I've written a thread concerning this a while ago asking help mith HMAC 512 encryption, @joreg helped a lot)
Market API async/callbacks: What do i have to look out for, in case i have multiple post request at the same time?
Any help on this topic would be hyper apreciated and i think this could be the start of something nice.
If we'd had a framework with access to a cryptomarket, i am shure we have a lot of ladies and gents here, eager to compete for the best autotrader ;) VL/vvvv only of course :P
Would be cool to hear from you guys! Happy new Year!
