You get something like this (formatted) when querying for ticker https://api.kraken.com/0/public/Ticker?pair=XXBTZUSD
{
"error": [],
"result": {
"XXBTZUSD": {
"a": [
"3906.00100",
"2",
"2.000"
],
"b": [
"3906.00000",
"4",
"4.000"
],
...
}
}
}
Third numbers (volume) in a and b are always positive whole numbers. They never contain fraction part. Given that unit of this ticker is XBT it looks absolutely unrealistic. Comparing with https://www.kraken.com/charts it also looks completely wrong. Could you please explain it?
