hi when i try to start it i get the following error. used to work well in january/february.

C:\Users\Aldo\AppData\Local\Programs\Python\Python36>python.exe ./start --exchanges Binance Kucoin Etherdelta Cryptopia Bittrex Bitfinex Poloniex --pairs ETH BTC LTC Traceback (most recent call last): File "./start", line 20, in <module> cmc = pymarketcap.Pymarketcap() File "C:\Users\Aldo\AppData\Local\Programs\Python\Python36\lib\site-packages\pymarketcap\core.py", line 54, in __init__ self.correspondences = self._cache_symbols() File "C:\Users\Aldo\AppData\Local\Programs\Python\Python36\lib\site-packages\pymarketcap\core.py", line 87, in _cache_symbols currencies = self.session.get(url).json() File "C:\Users\Aldo\AppData\Local\Programs\Python\Python36\lib\site-packages\requests\models.py", line 884, in json self.content.decode(encoding), **kwargs File "C:\Users\Aldo\AppData\Local\Programs\Python\Python36\lib\json\__init__.py", line 354, in loads return _default_decoder.decode(s) File "C:\Users\Aldo\AppData\Local\Programs\Python\Python36\lib\json\decoder.py", line 339, in decode obj, end = self.raw_decode(s, idx=_w(s, 0).end()) File "C:\Users\Aldo\AppData\Local\Programs\Python\Python36\lib\json\decoder.py", line 357, in raw_decode raise JSONDecodeError("Expecting value", s, err.value) from None json.decoder.JSONDecodeError: Expecting value: line 1 column 1 (char 0)

Hi, i run the test cmd and get the following error:
Traceback (most recent call last):
File "./start", line 33, in
markets = cmc.markets(coin["id"])
TypeError: string indices must be integers

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
File "./start", line 35, in
markets = cmc.markets(coin["symbol"])
TypeError: string indices must be integers
I try to use the pymarketcap's ticker(100) directly, it seems the data structure outer is just data?
Is there anything wrong?
Thanks

A:\Documents\arbitrage-moments-master>python3 start.py
Traceback (most recent call last):
File "start.py", line 25, in
if market['percent_volume'] >= MINIMUM_PERCENT_VOL and market['is_updated'] and (trades_into in ACCEPTABLE_TRADING_PAIRS or ALL_PAIRS):
KeyError: 'is_updated'

not to sure what's causing this error

Is there a way to get rid of the korean won entries, for example? I want to see all U.S. supported exchanges, including ones I might not know about at the moment, but I don't want to see ones that I can't use, such as the Chinese and Korean ones.

i should fix this sometime

I think there can be more profit potential in the implied cross pairs. I.e. derive ethbtc pair from ethkrw, btckrw on Korean exchanges, rather than just the mainstream ethbtc pair on bittrex.

Do a triangle arbitrage in binance?

iota/btc - iota/eth - eth/btc

or

iota/bnb -iota/eth - eth/btc

I downloaded python and your code but I'm confused about how to get it running from there. I tried navigating to the directory I have the folder in and typing start into a python command prompt, but that doesn't seem to work. I also tried using a regular command prompt, but that didn't seem to work either.

I'm sure there's some kind of build process that I'm missing here, and I was wondering if you could give me some step by step instructions to help me get this running. I know this is a script kiddie question but I'd really appreciate your help since I don't understand python very well.

Thanks in advance!

Hi,

Running the script with Python 3.6.3, I have an attribute error:

Traceback (most recent call last):
  File "./start", line 33, in <module>
    markets = cmc.markets(coin["id"])
  File "/home/u/arbitrage-chances/lib/python3.6/site-packages/pymarketcap/core.py", line 296, in markets
    marks = html.find(id="markets-table").find("tbody").find_all('tr')
AttributeError: 'NoneType' object has no attribute 'find'

I attach the complete output, including the command line used: output-arbitrage-chances.txt

Hi,

Running the script with Python 3.6.4 on Windows 10, I have a type error:

Traceback (most recent call last): File "start.py", line 45, in <module> trades_into = market["pair"].replace(coin["symbol"],"").replace("-","") TypeError: string indices must be integers

I attach the complete output, including the command line used: output-arbitrage-chances.txt

I had the idea to search for crypto arbitrages, but i have nearly no skills in python. Sorry.
I was not able to scan the CMC-API for different prices on different exchanges.
Searching for a solution i found this sweet little peace of stuff. Thank you for your work!

But my console output and the Python linter at pythonbuddy.com tell me something about a syntax error in line 60.

Is this really a problem or am i wrong?

I'm sorry i know this isn't your package but really want to use your script and ive tried installing pymarketcap with pip and from source and I keep getting this dependency error if anyone knows a solution. Thank you either way!
