ws_capacity not workingx about bitfinex-api-py

[itsdeka]

Thanks for the video.
Using 3.9.2 I can reproduce it. Please, consider the possibility of downgrading to 3.8 where this issue does not exist.
I'll try to find a solution.

@Bwahharharrr I removed nest_asyncio and found another way.
Can you please give a look? Your example looks good on my end.

@itsdeka Run on my system and the test did indeed subscribe to the 4 tickers opening up 2 separate channels, so that much looks good.
I'll update my end in the next few days and continue using and report back any further related issues but so far looks like good job

[Bwahharharrr]

Can you confirm @itsdeka ?

Hello @Bwahharharrr, sorry for the late reply.
I have tried to run your code with websockets 10.0, 9.1 and 8.1 and I have never seen the error described.
Which version of Python are you using? All the other dependencies are as specified in requirementx.txt?

[Bwahharharrr]

Hi @itsdeka - python version 3.9.2, i just reproduced the test again on an entirely new virtual machine, you can see the log here:

Keen to upgrade rather than downgrade;
I just tested on 3.9.9, same issue/error.

• Can confirm it does work on 3.8.0

@Bwahharharrr hello, I found a solution to support Py >= 3.9.
Please I'd appreciate if you could confirm that everything works as expected on your end with these changes (#180).

@itsdeka I have run the marketorders branch from your repo with the asyncio_nest code in, which having used before, I thought, 'yes, this will work running this new even loop inside the existing one', however. The code failed to execute properly, and here is why:

As per the original code example provided: It attempts to subscribe to 4 tickers, opening up 2 websockets.
After this nest_asyncio fix, the 2nd websocket connection is at least opening, which is an improvement. HOWEVER.. It never subscribes to the channels.

Python 3.9.2
websockets 9.1
asyncio 3.4.3
nest-asyncio 1.5.1

See here.

import os
import sys
from bfxapi import Client, Order

bfx = Client(ws_capacity=3)

tickers = ['tBTCUSD','tETHUSD','tSOLUSD','tLTCUSD']

@bfx.ws.on('connected')
async def blah():
    for t in tickers:
        await bfx.ws.subscribe_trades(t)

@bfx.ws.on('subscribed')
async def subscribed(data):
    print(f"Subscribed to {data.channel_name}, {data.symbol}")

@bfx.ws.on('new_trade')
def log_trade(trade):
    print ("New trade: {}".format(trade))

bfx.ws.run()

Great, thanks for your feedback.
I am on it.
