Description

Good afternoon, everyone!

Please specify why when 2 or more orders are placed sequentially on EXMO, the nonce of one order is replaced by another? LTC_BTC nonce 1729621203456 BCH_BTC nonce 1729621203556 Error open order LTC/BTC on EXMO: exmo {"result":false,"error":"40009: The nonce parameter is less or equal than what was used before \"1729621203556\""}

Hello @89d55d5288,

Thanks for reporting it.

Is this issue deterministic?

Hello @carlosmiei, Thank you for your question.

I can't identify a pattern. It happens intermittently.

Additionally, there is an error. The order is sent to the exchange. The exchange opens the order, but the response comes {‘result’:false, ‘error’: ‘Error 50052: Insufficient funds’}.

It is also intermittent.

@89d55d5288 Not sure what we can do differently here tbh, because we can't be more granular than milliseconds and I highly doubt that the order X+1 has the same/smaller timestamp/nonce than the order X.

[carlosmiei]

I think this might be an issue on the exchange side

[89d55d5288]

@carlosmiei I.e., the number is exchanged at the exchange? This sounds logical following the answer received from the exchange. What about the situation with Insufficient funds?

@89d55d5288

That or they're not respecting the order of the requests.

What about the situation with Insufficient funds?

That also seems to be a problem with their engine, ccxt creates request deterministically if you provide the same symbol/type/side/price/amount

@carlosmiei Thanks for answers
