Hi! Thx for reporting this, I'll take a look into it asap.

[kroitor]

Ok, I fixed the error reporting in Python3, but LiveCoin looks like it's on maintenance now...

ccxt.errors.ExchangeNotAvailable: livecoin POST https://api.livecoin.net/exchange/selllimit 503 
Service Temporarily Unavailable  (possible reasons: invalid API keys, bad or old nonce, exchange is down or offline, on maintenance, DDoS protection, rate-limiting, 
{"success":false,"errorCode":503,"errorMessage":"Service is under maintenance"})

1. Can you please update to version 1.9.54+ and retry the same code to check if the output is clear now?
2. Also, can you try to place the order with livecoin website and compare it to the output of ccxt?
3. Can you fetch the balance from livecoin with ccxt?

Need to verify the above to leave no room for an error, and to make sure their private API is working.

We will stand by for a report from you. Thx!

[mazertwo]

Wow, thank you for fast answer! But i cant test now. LiveCoin in maintenance now.

[kroitor]

Ok, let's wait and retry later then? ) Livecoin is on maintenance too often... I'll stand by for more info from you. Thx!

[kroitor]

(Can you check if you're able to open the same order with their website?)

[mazertwo]

Yes, i can now open this order manually.

[mazertwo]

And can fetch any info about pair and other market data.

[kroitor]

@mazertwo ok, then I'll have to investigate further into this. Thx for your involvement, I'll get back to you asap!

[mazertwo]

Can YoBit block me for made orders via API if i change security parameters? 48 hours?

[kroitor]

@mazertwo yes, if you hit their rateLimit, described here:

https://github.com/ccxt-dev/ccxt/wiki/Manual#rate-limit
https://github.com/ccxt-dev/ccxt/wiki/Manual#overriding-the-nonce

Though, I don't think it's 48 hours. If they blocked you, try a proxy: https://github.com/ccxt-dev/ccxt/wiki/Install#proxy to see if this is bound to your API key or to your IP address. Also, you can retry in an hour to see if that changed, they may be blocking some countries during periods of high load, then unblocking them again.

Here's a few examples on how to do periodic requests (aka long-polling) without hitting the rate limit:
https://github.com/ccxt-dev/ccxt/blob/master/examples/py/tickers.py
https://github.com/ccxt-dev/ccxt/blob/master/examples/py/fetch-ohlcv-sequentially.py
https://github.com/ccxt-dev/ccxt/blob/master/examples/py/async-generator-ticker-poller.py

You should stay below rate limit to avoid ban.

[mazertwo]

I can get any data from Livecoin via API, but cant made orders via API.

[kroitor]

@mazertwo does fetch_balance work?

[mazertwo]

Yes

[kroitor]

@mazertwo then give me some more time on this, plz. I'll be back.

[mazertwo]

[kroitor]

@mazertwo did you have a chance to try their API with any other software previously? Looks like a common problem, though, I'm still investigating...

[mazertwo]

No, just via ccxt. Strange problem.

[kroitor]

@mazertwo ok, here's their Python 2.7 example from their website, can you try it? I'll do the same. Edit the price, volume and keys below:

import httplib
import urllib
import json
import hashlib
import hmac
from collections import OrderedDict

server = "api.livecoin.net"
method = "/exchange/buylimit"
api_key = "gJx7Wa7qXkPtmTAaK3ADCtr6m5rCYYMy"
secret_key = "8eLps29wsXszNyEhOl9w8dxsOsM2lTzg"

data = OrderedDict(sorted([('currencyPair', 'BTC/USD'),('price', '100'),('quantity', '0.01')]))

encoded_data = urllib.urlencode(data)

sign = hmac.new(secret_key, msg=encoded_data, digestmod=hashlib.sha256).hexdigest().upper()

headers = {"Api-key": api_key, "Sign": sign, "Content-type": "application/x-www-form-urlencoded"}

conn = httplib.HTTPSConnection(server)
conn.request("POST", method, encoded_data, headers)

response = conn.getresponse()
data = json.load(response)
conn.close()

print data

[kroitor]

The above script replies 503 to me... And you?

[mazertwo]

Me too...

[kroitor]

@mazertwo so, it seems like a permanent Livecoin issue with their API, not the library? Can you open a ticket with their support? If their own example fails, then they have a problem with their API... I sent my request to them, but got no reply for now. Would be great if you double the effort, so, maybe, together we can wake them up...

[kroitor]

@mazertwo one thing to clarify: when trying, you did replace the credentials in the script above for your own keypair, right?

[mazertwo]

Sure, i put my keypair. LiveCoin support is so sloooow. 1-2 weeks for answer.

[mazertwo]

My native language is russian. Sorry for my bad english.

[xpl]

@mazertwo По-русски мы тоже понимаем, не стесняйся :)

[kroitor]

@mazertwo yeah, but, I'm afraid, only Livecoin guys themselves can resolve this issue for us...
No problem with your English at all, it's all clear! Thx for your answers btw! Really helpful! I suggest, let's open a ticket and wait... Even if they reply in 2 weeks, it's better than nothing. Can you skip Livecoin and go on with your other tasks within ccxt for now? If you don't mind, I would close this issue until they reply, and then I'll get back to you, or maybe you will have better luck and notify us all quicker. How's that for you?

[mazertwo]

I have same error with 'ETH/BTC' and other pairs in LiveCoin exchange. Not only with 'LTC/BTC'.

[mazertwo]

xpl, рад приветствовать вас и всю команду!

[xpl]

(but we prefer English for everyone else's convenience)

[kroitor]

@mazertwo

I have same error with 'ETH/BTC' and other pairs in LiveCoin exchange. Not only with 'LTC/BTC'.

Yeah, looks like a broken endpoint on their side... So, what do you think on my suggestion above?

[mazertwo]

I connect with support via ticket.

[kroitor]

Ok, I'm closing this for now, let's wait for their reply, if I get one, I'll update you here. Feel free to reopen it anytime, if you have any other questions! Thx again!

[kroitor]

Good news, @mazertwo! The cause of the problem was finally found and fixed in 1.9.273+. So, Livecoin limit orders should work normally now. Plz, let us know if you still have problems with it after upgrading. Thx!

[kroitor]

One more minor fix added in 1.9.273. So, this issue should be resolved completely now.

[DeeDab]

Now, that's all. I hope it will be useful and my help was useful to you @kroitor )

[kroitor]

@DeeDab it was, indeed! Thx a lot for your involvement!
