Topic: [ANN] MarginBot - A Bitfinex Margin Lending Management Bot (Read 45937 times)

Hello,

Does this bot work well with currencies other than USD? For example, does it work with ETH or BTC? If so, is there any settings I need to manual change for ETH or BTC?

Thanks

Since you were already able to make it work once, just start with a fresh VM and from scratch, if it is only a hobby project?

A possible issue could be that the clock in your VM is off, read up on "NTP" how to fix that.
 

Wondering the same thing as I'm in the same boat.  It's not a critical issue but the reports from Bitfinex show the correct amount. The graph seems to have a maximum value set on the USD balance axis.

Very interesting project!

Can you elaborate a bit on what algorithm the bot uses to determine the lending rate at which it will put the offer?

Hello, I just installed last version and I found a strange thing in the graphical view of USD return.
My USD balance is more than 10k ( in the funding settings page it shows correct amount) but in the graph it stop right axis to 10k.
is there a way to fix it?

thanks !

Ahh, yeah that would make sense.  Never considered the funding wallet would have a coin in it that can't be lent.  I'll try to trap for that better in a future build, but for now, just transferring those coins to another wallet will fix it.

Thanks for the quick response. Based on your reply, I just realized that the code is trying to get the lendbook on BTG because I have a positive value in my Funding Wallet for BTG. This happened automatically as part of the bitcoin fork. Bitfinex put the BTG coins into the funding wallet automatically because that is where my BTC was I guess. I moved the BTG out of my BTG Funding Wallet to my BTG Exchange Wallet and that made the Bot code stop trying to get the lendbook data for BTG. It seems to be running correctly again. Hopefully this post will help anyone else that hits this problem. Thanks.

The problem is bitfinex isn't allowing Margin Funding for BitcoinGold yet, only exchange trading.  You can always check the "Funding" dropdown menu for available coins to lend on margin.

I think the new coin BTG may have broken something. Starting on 10/24 my error logs on v1.08 filled up due to an infinite loop.

It seems to all start with this issue:
[Tue Oct 31 01:04:42.359667 2017] [:error] [pid 3349] [client 52.6.250.144:60840] PHP Warning:  file_get_contents(https://api.bitfinex.com/v1/lendbook/btg/?limit_asks=500&limit_bids=0): failed to open stream: HTTP request failed! HTTP/1.1 400 Bad Request\r\n in /var/www/html/bitbot/inc/ExchangeAPIs/bitfinex.php on line 229


Notice the "BTG" in the URL.
https://api.bitfinex.com/v1/lendbook/btg/?limit_asks=500&limit_bids=0

This returns {"message":"Unknown currency"}

Change "btg" to any other coin code and it works fine. It seems the code is pulling back all coins and trying to get the lending book, so when BTG started coming back as a valid coin, it tries to get the ending info and fails.

Any suggestions on a quick fix or maybe a code update?

There is a trailing " on the end of the crontab entry you posted. Should it be there?

Try using the full path to the wget command. The $PATH used by cron can be different than the $PATH you have when logged in.

Look in /var/log/cron to check what is happening.

You should also try running the command on the command line.

Thanks for the awsome bot, it forces me to learn web server and linux from almost 0. And after a few hours, I got my bot running! The only thing I am missing is that I can't get my hourly cron job working somehow. The 10-min cron is working well.

In my "crontab - e", I got one line for the 10-min cron job copied from installation, and next line for the 1-h cron job. But the web server kept giving me "It appears you have not set up the hourly cron, or it hasn't been running. Check to make sure your cronjob contains a job similar to:
5 * * * * wget -qO- xxxxxxxxx/bot/crons/HourlyCron.php >/dev/null 2>&1". xxxxx is my address. It seems all correctly copied as instructed. Any suggestion for a noob?

I think the 10-min cron is doing all the lending, and 1-h cron only for the statistics, right? I think I can live without it.

Thanks,

Awesome. Thanks so much for the quick response.

Nothing to be concerned about.  When I added back in Crypto Pairs, I check against a variable that doesn't always have all the possible pairs in an array.  In the next build I will update the check so that it makes sure the pair exists, and if it doesn't it'll fail silently (as it should do now) so that nothing gets logged.  Other than making your logs a bit longer than they should be though, this won't effect the bot at all as it is.

I'm a new user of the MarginBot. So far so good. Many Thanks to HowardF

I need help with some error messages.

I downloaded the latest and set it up again yesterday on 10/15. It shows version 1.08. I'm running on PHP5.6 and MySQL 5.5 on AWS Linux on an EC2 server. I did modify the DB to add NEO as my 14th currency pair and I only left USD, BTC, ETH and NEO as active. The rest I set to zero. Then I set my cron jobs and everything appears to be running. I saw it post two NEO orders, so it is working.

However, I see the following errors over and over in the httpd error_log. Should I be concerned? (not my real IP, obviously).

Thanks in advance for any advice. MT

One other thing, this is just a Notice, so it shouldn't prevent the script from continuing to run.  It actually should be suppressed from hitting the logs, but you probably have error reporting set pretty high in your php configuration.  Still shouldn't cause any issues, its just going to write a lot of notices to the logs.

( I will tweak that line in future builds so that it won't throw a notice even on high error settings. )

Hmm.. this is making me think your sql server doesn't have enough space for queries to run correctly.  I can't imagine marginbot making any queries that would cause this though, all the marginbot tables are relatively tiny.   Are you running something else on this server that does a lot of work on your MySQL server?

Note/disclaimer: I have little experience with php programming

I have a domain hosted on which has one subdomain.
On this subdomain i installed MarginBot. When i got to the correct address i noticed the webpage just kept on loading. I checked the server logs and found out they where being flooded with the message:


[Fri Oct 13 20:26:06.405827 2017] [proxy_fcgi:error] [pid XXXXX:tid XXXXXXXXXXXXXXXXXX] [client xx:xx:xx:xx:XXXXXX] AH01071: Got error 'e/XXXX/domains/XXXXX.XX/public_html/marginbot/inc/ExchangeAPIs/bitfinex.php on line 78\nPHP message: PHP Notice: Undefined index: price in /home/XXXXX/domains/XXXXXX.XX/public_html/marginbot/inc/ExchangeAPIs/bitfinex.php on line 78\nPHP

I looked up the file bitfinex.php and went to line 78. Here below is the function that line 78 belongs to:

`    /* Data posting query, for detailed API calls */
    function bitfinex_query($method, array $req = array()) {
        // API settings
      
        $req['request'] = '/v1/'.$method;
        $this->nonceInc += 1;
      $req['nonce'] = (string)$this->nonceInc;
      if($req['price']){$req['price'] = (string)$req['price'];}
      
        // generate the POST data string
        $reqData = base64_encode(json_encode($req, true));
      $post_data = http_build_query($req, '', '&');
      //print_r($post_data);
        $sign = hash_hmac('sha384', $reqData, $this->apiSec);
 
        // generate the extra headers
        $headers = array(
         'X-BFX-APIKEY: '.$this->apiKey,
         'X-BFX-PAYLOAD: '.$reqData,
         'X-BFX-SIGNATURE: '.$sign
        );`


Further information:
-When installed MarginBot i then configured my bitfenix account using the MarginBot webpage gui. (I could still access and use the webpage
-I made a second user account

After the things mentioned above the webpage became unaccesable. I'm guessing i'm making an obvious mistake here which i am sure one of you can assist me with.

Further more an other error popped up in the server logs:

[Fri Oct 13 20:26:23 2017] [proxy_fcgi:error] [pid XXXXX:tid XXXXXXXXXXXXXX] (70007)The timeout specified has expired: [client XX.XXX.XX.XXX:XXXXX] AH01075: Error dispatching request to : (polling)

However i'm betting this is merely the result of endless loading due to timeout

And after a long while it will display :


THERE HAS BEEN A DATABASE ERROR
Please Contact Support If this error persists.
1021 - Disk full (/tmp/#sql_16ed_0.MAI); waiting for someone to free some space... (errno: 28 "No space left on device")

Wow, just noticed that even though I replaced all the folders from your master, my bot folder files were the old deponzit ones, not yours! Sorry for the user error! Everything is all set up, thanks anyway for the reply!

Hmm...  I'm definitely at a bit of a loss here.  I don't use the column 'currency' anywhere.   Are you installing over a build of the deponzit fork?  I know he used a 'currency' row, and leaving any code from that fork in the folder when you install the base MarginBot would definitely break things.  He made changes to the core database layout that would not be compatible.
