Kraken createOrderWs about ccxt

[fl0wo]

Hi, indeed it's very hard to reproduce.

I have seen this on avg 1 between 200-300 trades.
And for some reasons it more often when the "amount" is high (almost as if the order is not completed immediately it throws an error, and for smaller orders with lower size that get immediately closed not)

But I'm not sure, for now I just removed the createOrderWs usage, and will monitor this the following days.

I'm closing this as not an issue, will re-open it if possible, when I see again the same in case.

Hello @fl0wo,

Technically yes it is possible, we might be misparsing an error message or something like that but it's very hard to tell without more information such as logs/ stacktrades/ steps to reproduce the issue.

I tried to run something like this, but had no luck

    for i in range(0, 20):
        order = await exchange.create_order_ws('LTC/USDT', 'limit', 'buy', 0.1, 50)
        print('created order', order['id'])
        await exchange.cancel_order(order['id'], 'LTC/USDT')
        print('canceled order', order['id'])

@carlosmiei Regarding your test code, I'd rather do something like:
(again, only on Kraken)

for ... 20 {
 
  try {
        await createOrderWs( LTC... )
  catch(e) {
       await createOrder( LTC... ) // non ws
  }

  await sleep 10sec

  // fetch new orders on LTC
  // if there are 2 new orders on LTC there's an issue (means we placed 2 times the same order)

}

Ok I removed createOrderWs and now i dont see double trades no more.

I confirm createOrderWs errors are weird for Krakne

@fl0wo Did you manage to get a verbose log?
