All ‘price’ precisions are None. The information is not available in the ‘info’ section either. I believe this is because the end point to fetch this info was changed in the ccxt code recently.

@JovianMoon you’re right I had my master branch outdated so I got confused for a bit I’m sorry for that. I’ll fix that line soon

@JovianMoon sorry I misinterpreted the issue initially, as you said the information is not available in v2 and yes we recently updated fetch_markets to use v2 because we need to follow exchanges’ recommendations and adopt their new api versions because they add new features, and eventually v1 will be deprecated. Nonetheless, v2 is not in the final state yet so this information might be added in the future we’ll pay attention to that. Moreover, if that information is crucial to you, consider using the bitfinex (v1) instead of bitfinex2 (v2).
