i can tell from your traceback that you are on an old version of the library. What version are you using?

[leonwang908]

I downloaded the library from github directly and the version is 2.2.2

@leonwang893 ok can you provide a reproducible example then? the code is referencing book data, but all i see is an add_feed for trade data

[leonwang908]

Hi, here is my code. btw, I could run my code on version 1.7.0

`from cryptofeed import FeedHandler from cryptofeed.callback import BookCallback, TradeCallback from cryptofeed.defines import BID, ASK, L2_BOOK, TRADES from cryptofeed.exchanges import Bitflyer from datetime import datetime import asyncio import time import pandas as pd import numpy as np

async def book(feed, symbol, book, timestamp, receipt): date = datetime.utcfromtimestamp(timestamp).strftime('%Y-%m-%d') asks_df = pd.DataFrame.from_dict({'price': book[ASK].keys(), 'size' : book[ASK].values()}) bids_df = pd.DataFrame.from_dict({'price': book[BID].keys(), 'size' : book[BID].values()}) asks_df.insert(0, 'ts', timestamp) bids_df.insert(0, 'ts', timestamp) print(asks_df) await asyncio.sleep(1)

async def trade(feed, symbol, order_id, timestamp, side, amount, price, receipt): current_ts = time.time() date = datetime.utcfromtimestamp(timestamp).strftime('%Y-%m-%d')

def main(): f = FeedHandler() f.add_feed(Bitflyer(symbols=['FX-BTC-JPY'], channels=[TRADES], callbacks={TRADES: TradeCallback(trade)})) f.add_feed(Bitflyer(symbols=['FX-BTC-JPY'], channels=[L2_BOOK], callbacks={L2_BOOK: BookCallback(book)})) f.run()

if name == 'main': main()`

[bmoscon]

ok ,the error is because your callbacks have the wrong definitions. The callbacks only take 2 params - data object and receipt timestamp. Please fix that. look in examples/demo.py for an example if you need one

Thanks for your help. I updated my code, and this time I can get data for 'BTC-JPY' but 'FX-BTX-JPY' is still a issue

Traceback (most recent call last): File "C:\Python38\lib\site-packages\cryptofeed\exchange.py", line 137, in std_symbol_to_exchange_symbol return self.normalized_symbol_mapping[symbol] KeyError: 'FX-BTC-JPY'

[bmoscon]

you can see all the supported symbols by looking at the list returned by the .symbols() method

Solved! Big thanks!
