x.Stream.subscribe.getCandles bug (caused by xOpenHub server side logic)

[peterszombati]

x.Stream.subscribe.getCandles doesn't working if you didn't do a price history request for specific symbol
example with BITCOIN:

x.Stream.subscribe.getCandles('BITCOIN')
        .catch(() => { console.error('subscribe for BITCOIN failed')});

It won't work.
You have to do a request to BITCOIN price history then subscribe for candles
example with BITCOIN:

x.getPriceHistory({
  symbol: 'BITCOIN',
  period: PERIOD_FIELD.PERIOD_M1,
  ticks: -1
})

x.Stream.subscribe.getCandles('BITCOIN')
        .catch(() => { console.error('subscribe for BITCOIN failed')});

Is there anything you can do on your library side that is not a tiny hack since the root 'cause is located on XTB side ?
I'm curious, have you tried submitting a bug (through their help desk) on their side ?
PS: So far locally, I've found a better solution to do realtime computation of the candles based on the getTickPrices subscription, so I don't have to wait a minute to get a notification from their websocket.

Hi @solarfrantz
Today I sent an email to support @ xhub . pro

@solarfrantz btw they still didn't respond to me, I'm 100% they won't do any changes on their side:)

That's weird because Python code works fine:

import sys
import time
from xAPIConnector import APIClient, APIStreamClient, loginCommand

userId = 999999
password = 'blabla'

client = APIClient()

loginResponse = client.execute(loginCommand(userId=userId, password=password))

if not loginResponse['status']:
    print('Login failed. Error code: {0}'.format(loginResponse['errorCode']))
    sys.exit()

ssid = loginResponse['streamSessionId']

sclient = APIStreamClient(ssId=ssid)

sclient.execute(dict(command='getCandles', symbol='EURUSD', streamSessionId=ssid))

# make it run for 5 minutes
time.sleep(300)

sclient.disconnect()
client.disconnect()

You need official wrapper (xAPIConnector) from here: http://developers.xstore.pro/api/wrappers/
But I remember that about a year ago getCandles wasn't working at all. Maybe they fixed something?

@wtld I will check this later

@peterszombati any info here?

[mb-mb]

@peterszombati any update about this problem ?

Thank you very much for this information.
I thought I was going crazy. Calling getCandle sometimes worked for me, other times it didn't. I wondered in vain where I was going wrong, even though I was sure I hadn't changed any critical code. In desperation I tried Google and the very first link got me here. When I call the getLastChart function, then subscribe starts working. Weird but works for me.

Thanks again for this information!

2024 and found this issue is still alive. Using https://github.com/sgflt/xapi-websocket-client

2024 i odkryłem, że ten problem jest nadal aktualny. Używając https://github.com/sgflt/xapi-websocket-client

did you manage to solve the problem with Command: getCandles ?

[sgflt]

I just call getChartLastRequest before subscription and it seems to be working.

I just call getChartLastRequest before subscription and it seems to be working.

Thanks, I changed the calling order as you wrote and it worked <3
