Orders not placed in gdax even though the script says it did

[Lasterie]

Hi!

Love the script. I got buy orders working, but sell orders won't execute:

Wednesday, Aug 09, 2017 at 02:44:52 PM UTC || TWEET MATCHED || xxxxxxxxx
Wednesday, Aug 09, 2017 at 02:44:52 PM UTC || Available to trade: {{notzero}} LTC, {{notzero}}  ETH, {{notzero}} BTC, {{notzero}}  EUR
Wednesday, Aug 09, 2017 at 02:44:52 PM UTC || PLACING ORDER
{
    "size": "0.001",
    "type": "market",
    "side": "sell",
    "product_id": "BTC-EUR"
}
Wednesday, Aug 09, 2017 at 02:44:52 PM UTC || One of {"price", "funds", "size"} is zero! Order not placed.

This is the relevant part of the config:

    {
     	'handles' : ['edited'],
        'condition' : '"edited',
        'orders' : [
            { 
              	'side' : 'sell',
                'type' : 'market',
                'product_id' : 'BTC-EUR',
                'size' : '{available[BTC]}*0.01'
            }
	]
    }

Can anyone point me in the right direction?

"The smallest order you can place for a buy or sell trade on GDAX is 0.01 BTC, ETH, or LTC," from https://support.gdax.com/customer/en/portal/articles/2426595-gdax-limits-for-deposits-withdrawals-trades-and-balances, so that particular order isn't possible. But you're right, the reported error isn't accurate, and I think the code that handles checking for this is off too. (Looking to see if one of price, funds, or size is too close to zero is wrong; it should be checking only size.) If you'd like vickitrix to attempt to place all your orders anyway, remove the if statement here: https://github.com/nellore/vickitrix/blob/master/vickitrix/__init__.py#L212 .

Thanks! I ran into another issue though. Could it be correct that Gdax requires the input for "size" to have a maximum number of decimals? I have orders placed via the script, but they don't show up in gdax. When I put "0.1" hard coded as the size (instead of {{available[BTC]}*0.1), it works.

[nellore]

{available[BTC}*0.1 means "how much BTC you have available to trade times 0.1"; right now, you have so little available to trade (note that limit orders you've already placed will make your BTC unavailable to trade!) that multiplying it by 0.1 gives a value < 0.01.

[Lasterie]

That makes sense, but I place an order > 0.01:

Wednesday, Aug 09, 2017 at 03:56:07 PM UTC || PLACING ORDER
{
    "size": "0.015",
    "type": "market",
    "side": "sell",
    "product_id": "BTC-EUR"
}
Wednesday, Aug 09, 2017 at 03:56:07 PM UTC || Order placed.

And the order doesn't show up on gdax.

[nellore]

You've placed a market order: http://www.investopedia.com/terms/m/marketorder.asp . It's executed immediately. To see what went down, click your gravatar in the upper right on GDAX, then click Fills.

[Lasterie]

Yes, I checked but the orders are not there. There is one: an order of 0.01000000. It is placed by the vickitrix script. But by hard setting the "size" to "0.01" like this. This works immediatly and I see the order get filled.

   	'side' : 'sell',
                'type' : 'market',
                'product_id' : 'BTC-EUR',
                'size' : '0.01'

Instead of this (which doens't work):

   	'side' : 'sell',
                'type' : 'market',
                'product_id' : 'BTC-EUR',
                'size' : '{available[BTC]}*0.1'

Thanks so much for your quick replies!

[Lasterie]

Quick follow-up, I even tried with a larger amount, but the market order didn't get placed:

Wednesday, Aug 09, 2017 at 04:12:30 PM UTC || PLACING ORDER
{
    "size": "0.0287318114758",
    "type": "market",
    "side": "sell",
    "product_id": "BTC-EUR"
}
Wednesday, Aug 09, 2017 at 04:12:31 PM UTC || Order placed.

[Lasterie]

When I copy/paste the size in Gdax (the website itself, not via the API), it displays this error:

https://i.imgur.com/4TxjcaH.png

"Enter a valid value. The two closest values are 0,02873181 and 0,02873182"

Which led me to think, is there a maximum number of digits?

[nellore]

No idea what's going on here! Maybe we can debug live in the Gitter at some point? https://gitter.im/nellore/vickitrix .

[Lasterie]

Yeah sure, can you point me to a doc with info how to setup live debugging?

[Lasterie]

I tried it with a limit order, but the issue remains: the order doesnt get placed in Gdax, while the script says it said it did:

Config:

        'orders' : [
            { 
              	'side' : 'sell',
                'price' : '{inside_ask}',
                'type' : 'limit',
                'product_id' : 'BTC-EUR',
                'size' : '{available[BTC]}*0.1'
            }

Output:

    "price": "2885",
    "size": "0.0163228137379",

    "product_id": "BTC-EUR"
}
Thursday, Aug 10, 2017 at 06:39:01 AM UTC || Order placed.

I even tried it without the "*0.1", so with the entire btc funds. Script said it placed the order, but it didn't make it to gdax. Again, it does work when setting the size to a fixed value like "0.1".

[Lasterie]

I found it. As I thought, the problem is the number of decimals of "size" when the order is placed. I "hacked" this into init.py on line 127 to ensure the size is of a length of maximum 7 digits.

dough[account['currency']] = (account['available'][:7]) if len(account['available']) > 7 else account['available']

Now it works, the order is placed! Question: is this the proper way to do it? (I guess not, I'm not a good developer)

[nellore]

Interesting! I do not think the issue is that the size must be a maximum of seven characters; if that were true, you could not for example trade more than 9999999 of a given currency at once. It is possible not more than five decimal places are permitted here. You could try

dough[account['currency']] = '{0:.5f}'.format(float(dough[account['available']]))

. I'll look into this a bit more soon.

[Lasterie]

Thanks, that's a better approach indeed! I fixed the typo (the second "currency" should be "available"), but I still get this error when I run the script:

[Traceback (most recent call last):
  File "/usr/local/lib/python2.7/site-packages/vickitrix/__init__.py", line 596, in go
    get_dough(gdax_client, status_update=True)
  File "/usr/local/lib/python2.7/site-packages/vickitrix/__init__.py", line 127, in get_dough
    dough[account['currency']] = '{0:.5f}'.format(float(dough[account['available']]))
KeyError: u'_MYETHERBALANCE_'
]

[nellore]

Oh, sorry, the code shouldn't be changed there at all! Instead, try changing L195-L202 to

order[money] = '{0:.5f}'.format(float(eval(
                                    order[money].format(
                                            tweet='status.text',
                                            available=self.available,
                                            inside_bid=inside_bid,
                                            inside_ask=inside_ask
                                        )
                                )))

[Lasterie]

Thanks, tried that. The number of )))) is one too many in your last line.

[nellore]

Fixed! Thanks; I'll put this in the next version of vickitrix.

[Lasterie]

There's a small problem with this fix, it rounds the number to 5 decimals, but sometimes this leads to trying to sell a stack that is higher than you have. For instance:

Wednesday, Aug 16, 2017 at 02:46:21 AM UTC || Available to trade: 0.0000000000000000 LTC, 0.0000000000000000 ETH, 0.2076559273792344 BTC, 0.0000268925485000 EUR
Wednesday, Aug 16, 2017 at 02:46:22 AM UTC || PLACING ORDER
{   
    "size": "0.20766",
    "type": "market",
    "side": "sell",
    "product_id": "BTC-EUR"
}

You see that the available btc is 0.2076559273792344 but it tries to sell 0.20766, which you don't have.

I am having a similar problem, but i'm not sure that its down to rounding errors.

The size is the correct amount, but the order still didn't go through. Perhaps the limit price changed before it went through. Does gdax provide an error in this case in order to retry?
