Does it work with size=1 ?

@totoro said in Anyone use backtrader to do live trading on Bitcoin exchange?:

if the solution is here https://github.com/bartosh/backtrader/pull/6, why cannot we merge ?

I believe comments in that PR explain why it's not merged.

Btw, thank you @Ed-Bartosh for this fabulous work :)

You're welcome. It's actually a community work, not just mine. Many people contributed to it.
BTW, you have chance to do it too :)

@dedeco > Cloud you accept a pull request?

Absolutely.

BTW, You don't need to ask permissions for this, just submit PR. In worse case scenario it'll be rejected :)

@jacob > can you maybe open the option for 'issues' in your repo.

done

@sfkiwi yes, that issue was reported some time ago and there are 2 PRs about it: https://github.com/bartosh/backtrader/pull/13 and https://github.com/bartosh/backtrader/pull/6

Unfortunately they're both outdated and require rebase. Can you check if any of them fixes the issue for you?

@jacob Can it be done in more generic manner, i.e. independent from CCXT?

@jacob

I have the historical data in a .csv file. is there a way maybe to stitch the two together?

Currently backfill_from is not supported. I'll be happy to see this implemented. I hope it's not that hard to implement considering working example from ibdata.py.

@samy-david said in Anyone use backtrader to do live trading on Bitcoin exchange?:

self.broker.sell(owner=self,data=order.data, exectype=Order.Limit, size=limit_size, price=price)

What's the reason to use self.broker.sell instead of self.sell?

Can you sketch small script that I can run to reproduce the issue? Without this it'll be guessing game and it can take much longer.

1m timeframe data exists, all other timeframes (resample/replay) come with a missing symbol and potentially other data

I can't reproduce it. I can see 'symbol' attribute in the data after resampling:

$ ./test.py 
data.symbol after resampling: BTC/USD

$ cat test.py 
#!/usr/bin/env python

import sys
import backtrader as bt

cerebro = bt.Cerebro()

data = bt.feeds.CCXT(exchange="bitmex", symbol="BTC/USD", timeframe=bt.TimeFrame.Minutes)

cerebro.resampledata(data, timeframe=bt.TimeFrame.Minutes, compression=2)

print("data.symbol after resampling:", data.symbol)
