[cex.io ]unable to sell: Nonce must be incremented

[jordisk]

Hi,

I'm trying the bot with a real money trading and I got this error.

2017-03-18 12:09:50 (INFO):	Attempting to SELL 0.38605 ETH at cex.io
2017-03-18 12:09:50 (DEBUG):	SELL 0.38605 ETH @ 36.5015 EUR
2017-03-18 12:09:50 (INFO):	Wanted to buy ETH but the amount is too small (0.000000000000) at cex.io
2017-03-18 12:09:50 (INFO):	Attempting to SELL 0.38605 ETH at cex.io
2017-03-18 12:09:50 (DEBUG):	SELL 0.38605 ETH @ 36.5015 EUR
2017-03-18 12:09:50 (ERROR):	unable to sell: Nonce must be incremented
2017-03-18 12:09:50 (ERROR):	unable to sell: There was an error while placing your order: Invalid amount

The api has full permissions and I've also created a new api/secret pair and still fails.

Any ideas?

Many thanks!

Will ook into this! Cex.io code is pretty old and has not been tested in a while I think.

Thanks @askmike! I've noticed that the minimum amount to trade in cex.io is 0.5 ETH. I've transferred more founds but the error persists.

I believe that you are sending nonce value which is lesser than or equal to nonce value you sent in the past.

I was facing same issue. I was using unix_timestamp as nonce in each request. My code was running fine on a server in timezone GMT-9. However, when i tested the code on my local machine (GMT+5), the server started giving nonce issues. This is obviously due to the fact that I was using nonce (unix_timestamp of my server) which was less than the nonce (unix_timestamp of my local machine).

I added increment of 2 days to my server timestamp and this error disappeared.

I am using this library which automatically updates the nonce. I think this specific error is caused by @jordisk using the same API key for different tools (especially since there is only one bug report since march).

Unfortunately cex.io is not enabled anymore..
