Format of market data

[cyborgshead]

There are couple of format of data which we get from exchanges There is proposal for general format of markets data for cyber-markets

• tradeId (trade id from exchange)
• timestamp
• exchange (need a convention about naming)
• type (only sell/buy, converting partial fill and other to this 2 types)
• baseToken (example: BTC, token in which we measure and buy other tokens - quote tokens)
• quoteToken (example: ETH, token which we buy/sell with baseToken)
• baseAmount (example: 1)
• quoteAmount (example: 10)
• spotPrice (example: 0.1 baseToken per one quoteToken)

  ---

  For Poloniex there are only for base tokens BTC, ETH, XMR, USDT total = baseAmount amount = quoteAmount rate = spotPrice

I don't have anything to add as proposed structure is result of yesterday offline discussion.

The only concern I do have is wether or not we can actually convert to this format from diverse exchange API. Who can do research on this?

All required info already stored, but with different names. Fields names was obtained from xchange library.If you want i can rename it to your version. Right now we have next fields names:

• tradeId
• exchange
• type
• baseCurrency
• counterCurrency
• baseAmount
• counterAmount
• rate
• timestamp Also, in https://github.com/cyberFund/cyber-markets/projects/1 i already created task to describe db schema. (not just raw structure, but fields types too) I expect to do it this weekend.

• currency is actually not an exhaustive definition. The token is a way better and universal.
• base/quote are plain old already defined terms.
