Last update has broken fetch_ohlcv with since parameter on Binance

• OS: Windows 10
• Programming Language version: python 3.7
• CCXT version: 1.42.8

After updating ccxt to 1.42.8 from 1.40.88 my code using fetch_ohlcv with the parameter “since” has stopped working and it returns an empty list. If I don’t use the since parameter it works.

Downgrading the library back to 1.40.88 has solved the problem

This code works:

exchange = getattr(ccxt, 'binance')()
await exchange.fetch_ohlcv('BTC/USDT', '1m')

This code doesn’t works

exchange = getattr(ccxt, 'binance')()
await exchange.fetch_ohlcv('BTC/USDT', '1m', 1613753220000)

I understand, don’t worry, it’s just that I don’t have the time to look into this on more detail right now. I will keep working with the last version of the library that worked for me and will investigate this later.

Thank’s for your help anyway.

@Ricardus312 i can’t help you without seeing the code, unfortunately. If my snippet works and your code does not – paste your snippet, but please make it as short as mine, or close to that, so that i would not have to invent it or edit it too much, something i could copypaste and run to reproduce your problem – as you understand, without the code we are pretty much guessing. I mean, just looking at two square brackets does not help find the cause of it or resolve it.
