ccxt: UPBIT: Cannot cancel open order using ccxt API

@coinaisseur thx for your help debugging it, appreciate your involvement!

Hi @kroitor

Thanks for the latest update. Now the fetchOpenOrders and cancelOrder functions work as expected.

Thanks again for all your help and time spent fixing this issue.

Hi @kroitor

I managed to solve my problem by changin a little bit the sign function in the upbit library. Instead of sending query in plain text, I changed the code to send its hashed form instead:

if (Object.keys(query).length) {
  const hash = crypto.createHash('sha512')
  const queryHash = hash.update(this.urlencode(query), 'utf-8').digest('hex')
  request['query_hash'] = queryHash
}

This is not the most elegant solution, but it works for me for the time being.

Thanks for your help.

Hi @kroitor

I’ve tried again to cancel order after updating ccxt, still to no avail. Here’s the verbose:

fetch:
 upbit DELETE https://sg-api.upbit.com/v1/order?uuid=333b5521-dbc6-4e99-a2c7-ced299fdc763
Request:
 {
  Authorization: 'Bearer <authorization_token>',
  'Content-Type': 'application/json'
}
 {"uuid":"333b5521-dbc6-4e99-a2c7-ced299fdc763"}

handleRestResponse:

}

For some reason, there’s a problem with the JSON construct ccxt is sending to the exchange. In the case of fetchOpenOrders, I managed to make it work by changing hostname to ccxsg.upbit.com/api. This didn’t work with cancelOrder though.

I also tested this script on a fresh new Windows server install with latest node.js version (12.13.1) and with latest libraries installed, but it didn’t work.

Thanks for your help.
