help getting started - strange values for coinbase ticker #1498

Closed npomfret closed 6 years ago

npomfret commented 7 years ago

Just following the getting start guides to get some tickers for GBP / BTC. I have connected to a few exchanges and the data looks fine except for the coinbase exchange which is returning the following:

Ticker [currencyPair=BTC/GBP, last=1994.30, bid=2558.46, ask=2584.19, high=null, low=null,avg=null, volume=null, timestamp=null]

The bid and ask look like very wrong, way to high (last price looks ok though). Maybe they're in USD!? And there are a bunch of nulls here too. I ran the same code for a few other exchanges and got more sensible looking data back:

Ticker [currencyPair=BTC/GBP, last=2036.8823, bid=2000.4208, ask=2036.8822, high=2037.9516, low=1910.1231,avg=null, volume=13.41790025, timestamp=1496504857000] class org.knowm.xchange.cexio.CexIOExchange

Definitely looks like a bug. Thanks.

Hi, getting the same bug for BTC/EUR where its actually returning back BTC/USD, probably based on user default currency preferences like the webpage.

This coinbase api seems to give back the right results: https://developers.coinbase.com/api/v2#get-buy-price https://api.coinbase.com/v2/prices/BTC-EUR/buy https://api.coinbase.com/v2/prices/BTC-USD/buy

Try the GDAX implementation instead.

timmolter commented 6 years ago

The coinbase V2 Api is not implemented. It seems like everyone is using the GDAX API for coinbase now.
