Yet Another Price Feed Mod

[toast]

Is this script spamming feed updates right now?

Actually I've updated the script to work with 0.4.25.
You can safely update now.

[emski]

Think we need an update to handle the new date format, "oldtime" is no longer parsed correctly.  This seems to work but I'm not 100% sure:

Code Select Expand

oldtime[ f[ "asset_symbol" ] ] = datetime.strptime(f["last_update"],"%Y-%m-%dT%H:%M:%S")

I'll look into it after work. For now you can use the feed through the old client.

I've pushed a fix to handle the btsx->bts name change on btc38 .

[emski]

I've pushed a check for malformed exchange reply (btc38 only for now).
It appears that there is an issue with btc38.
I'll investigate further tomorrow as it is 2:00 am here and I've driven about 600 km on Bulgarian roads today.

cool, emski yours is working for me now

The error in xeroc's script you see might be related to improper config file.
There are different variables in both versions. Make sure you use proper version.

example:

Code Select Expand


{                                                                                                                                       
  "bts_rpc": {
    "url": "http://10.0.0.16:19988/rpc",
    "username": ""
    "password": ""
  }, 
  "delegate_list": [ "delegate.xeroc"],
  "payaccount" : "delegate.xeroc",
  "maxAgeFeedInSeconds" : 2700,
  "minValidAssetPrice" : 0.00001,
  "discount" : 0.995,
  "change_min" : 0.5,
  "btc38_trust_level" : 0.7,
  "bter_trust_level" : 1.0,
  "poloniex_trust_level" : 0.5,
  "bittrex_trust_level" : 0.5
}

[emski]

My bad. I've committed not working version.
Should be OK now.

I still get errors with both emski and xeroc's updated script:

emski:
  File "./btsx_feed.py", line 125
    volume_in_btc[ mapAsset ].append(float(result[coin.lower()+"_btc"]["vol_btc"])*confi$
                                                                                                                                           ^
SyntaxError: invalid syntax


xeroc:
  File "/home/user/feed_xeroc/btsx_feed.py", line 433, in <module>
    if publish_rule() :
  File "/home/user/feed_xeroc/btsx_feed.py", line 47, in publish_rule
    elif fabs(myCurrentFeed[asset]-realPrice[asset])/realPrice[asset] > config["change_min"] and\
KeyError: 'change_min'

What arguments are you passing to the scripts ?
Example: "./btsx_feed.py GOLD BTC USD CNY EUR"

Are you sure you have the file as in github ?

Apparently BTER changed BTSX asset name to BTS.
I've pushed a quick patch to address that.
I'll try to make something more robust soon.

dito ... had my inbox filled with errors .. need to put hand on the script some more ..

I've updated with changes related to v0.4.24 .
I've merged some bugfixes (thanks to xeroc (python identation is tricky)).
