$15-25 USD / hour

I have an API interface that streams json data to the console. Its missing some of the traditional delimiters that you would find in a json stream to http webpage. I desire additional coding that would listen to the stream and write to an appropriate database. See attached for stream as it appears on the console. This will ultimately be for stock trading. More Detail: Phase 1 - Develop an API that will take json like stream (secutities/stock data) and write (asyncrohous) to a database. - approx. 8000 records/minute with 12 data elements/record for 10 hours/day, 5 days per week - need to select database platform (possibly unstructured) with strong real time analytic capabilities - 7 day data decay rate - eventually 28 days kept on seperate archive database Data stream structure: // Stocks Aggregate: { "ev": "AM", // Event Type ( A = Second Agg, AM = Minute Agg ) "sym": "MSFT", // Symbol Ticker "v": 10204, // Tick Volume "av": 200304, // Accumulated Volume ( Today ) "op": 114.04, // Todays official opening price "vw": 114.4040, // VWAP (Volume Weighted Average Price) "o": 114.11, // Tick Open Price "c": 114.14, // Tick Close Price "h": 114.19, // Tick High Price "l": 114.09, // Tick Low Price "a": 114.1314, // Tick Average / VWAP Price "s": 1536036818784, // Tick Start Timestamp ( Unix MS ) "e": 1536036818784, // Tick End Timestamp ( Unix MS ) } Nodejs script which generates this stream on the console is found Here: [login to view URL] See attached for the sample data stream.

@leadconcept

Greetings, I have read your project description, as per my understanding you have API interface that streams json data to the console which has some missing elements and now you want to collect data and save it within database which will be used for stock trading. Can you please confirm you have your own API or you are using any 3rd party API from which you want to collect data? Please provide details of that API and you have any existing system, if yes then please provide its URL. Also you mentioned about the attachment which is missing, kindly provide your attachment as well and explain more about your requirements. Look forward to hearing from you. Thank you, LEADconcept
