Crossover: IndexError: list index out of range (Bad data)

[decharel]

After hours of running crypto-signal I get the following error. I assume an error handling could avoid this crossover behaviour when there is bad data.

Beginning analysis of NEO/USDT
Exchange supplied bad data for pair NEO/USDT, skipping

maybe this can help you.
#299

not a good fix but it works

I'm seeing the same thing and noticing that it's retrying. Posting error here just in case it helps

I think that's actually a separate problem, but it will probably help me track down this one.

I run the app over all pairs on bittrex and also get the same error. Any fix?

Choose a different pair like BTC/USDT to make sure it’s not an issue with the BCH pair.

Hi @alonsovargas3 , everything goes fine if I only run it over a specific pair like BTC/USDT. Weirdly, the same error occurred on BHC/BTC regardless on which market exchange.

[alonsovargas3]

That's because BCH is no longer a coin - it forked and you have two: BCHABC/BTC and BCHBV/BTC - I believe they both inherited the BCH historical data.

Today, April 4, these seem to be the correct pairs on Bittrex:

BSV/BTC - Bitcoin SV
BCH/BTC - Bitcoin Cash

Candle periods: '1m', '5m', '30m', '1h', '1d'

[alonsovargas3]

Good info. Also, in the error message I saw the following: Invalid data encountered while processing pair HSR/BTC, skipping Looks like you just need to make sure your config file has the right pairs.

So far what I need to do to scan all pairs is to list all pairs in the config except the ones which failed, right?
Roger that. Thank you, everyone! 💃

The program ignores invalid pairs, It doesn't cause any error because of that.

By the way, take a look at the development branch. There are many interesting things in the process.
