communicating with API, poloniex.com and gatehub.net

This program has to work with more sites, but now only [login to view URL] and [login to view URL] [login to view URL] [login to view URL] Program has to login to site through API A. get historical data once a time and then once a day B. regurarly, many times a second: 1. get current data: ¨ for all or only for some markets: - all the bids and all the asks - my open orders - my satisfied orders and in what volume - last trades with volume for [login to view URL] all that for exchange and for margin also 2. from this data I will make a decision what to buy, what to sell and what to cancel (I make only this part of a program myself, for testing purposes it will buy for some small sum cryptocurrency pair, which has the biggest growth in last hour and sell opposite for testing it will send the request for the price so that it will not be filled for example: BTC-USD pair is this offer right now bid ask 2488 2500 2487 2503 2450 2506 So program sends a request to buy at 1 and sell at 10000000 3. according to my decision program ASAP sends a buy, sell or cancel requests to API. 4. controls if my orders was accepted by API C. once a half an hour controls my money if my money is under some limit, it stops trading D. according to my conditions - program will send me an email or starts ringing E. all these things has to be error-proof, take care of every error api can send F. program saves automatically data I want ============================================== The best solution for me is to write it in C# But: on [login to view URL] is written: RippleAPI is the official client library to the Ripple Consensus Ledger. Currently, RippleAPI is only available in JavaScript. One person told me that c# is technically incapable of talking to javascript so if it is true, then help me to decide which language suits best if not, then C# is my favourite, if it will not make the response time much longer The program should be that way so that he can easily adopt another sites It should at least read btc-czk rate from [login to view URL] and czk-usd rate from [login to view URL] ======================================= So you write the whole code except of part where I decice what to buy and what to sell accoording to data your program provided. Your code also makes orders and verifies that there was being accepted. Also controls if they were taken or not and has possibility to cancel them ASAP. You makes examples so that I can write my part of code easily. it will also save my balance every 10 minutes.
