AttributeError: module 'ccxt.async_support' has no attribute '/'

Hello,

Thank you for this very useful application. But i have some issues when running, here is my stack trace:

"C:\Users\NV Master\AppData\Local\Programs\Python\Python36\python.exe" "C:/Users/NV Master/Documents/arbitrage/peregrine-master/peregrine-master/examples/example.py"
Traceback (most recent call last):

  File "C:\Users\NV Master\Documents\arbitrage\peregrine-master\peregrine-master\peregrinearb\async_find_opportunities.py", line 52, in __init__

    exchanges = [getattr(ccxt, exchange_id)() for exchange_id in exchanges]
AttributeError: module 'ccxt.async_support' has no attribute '/'

for this example:

from peregrinearb import get_opportunity_for_market
import asyncio

collections_dir = '/Users/wardbradt/cs/peregrine/'
opportunity = asyncio.get_event_loop().run_until_complete(get_opportunity_for_market("BTC/USD", collections_dir))
print(opportunity)

what refer to collections_dir ? Otherwise other examples in the project are working fine.

thanks for your help.

Thank you for pointing this out. This is an outdated example, which I will fix. You should not pass collections_dir to get_opportunity_for_market. So the correct code would be:

from peregrinearb import get_opportunity_for_market
import asyncio

collections_dir = '/Users/wardbradt/cs/peregrine/'
opportunity = asyncio.get_event_loop().run_until_complete(get_opportunity_for_market("BTC/USD", collections_dir))
print(opportunity)

However, I think there are some other issues impeding this snippet from running successfully. I will fix them.

In the response that you have mentioned as resolution to what refer to collections_dir ? collections_dir is still being passed.Can you please tell what should be value of collections_dir ?

@alvedys Well you can try switching to the 'working' branch and execute the example without the collections_dir parameter as the author has mentioned. But I am still getting errors for the other examples
