Yet another nonce problem #20

Closed georgiosd closed 8 years ago

georgiosd commented 8 years ago

Hi all,

I'm not developing on Node but hoping you guys can give a hand, having trouble with nonce like so many others before me lol.

I use a semaphore to make sure only one nonce is generated and the response is received before trying another one but still getting a nonce error.

From fiddler capture, the requests in order (added nonce header for debugging):

POST https://api.kraken.com/0/public/AssetPairs HTTP/1.1
nonce: 108622843

POST https://api.kraken.com/0/public/Depth HTTP/1.1
nonce: 146190498

POST https://api.kraken.com/0/public/Trades HTTP/1.1
nonce: 156578556

POST https://api.kraken.com/0/private/AddOrder HTTP/1.1
nonce: 171383828

Response to AddOrder:

{"error":["EAPI:Invalid nonce"]}

What else could be wrong??

Solved it after chatting to Kraken chat (only discovered after coming here)...

For anyone passing by this issue, two notes:

The public calls are rate-limited the same for all people connecting to Kraken regardless of Tier access so there's no point signing the calls like I have done above
The nonce must be included in both the API-Sign signature hash and as a POST url-encoded parameter

For posterity, and those looking for answers, I fixed my nonce issues by bumping the tolerance setting on my api key. Its not posted very well in the docs, but you can specify a threshold that will not trigger a nonce exception. I set mine to 15000000 (15s) since this library signs requests in nano seconds.

I just use multiple API keys.
