class CoingeckoUniverse

Bases: object

Coingecko data universe.

• Manage loading and saving Coingecko data in a flat file database

• Create id and address lookups for tokens

• We provide a default bundle of first 1000 tokens as DEFAULT_COINGECKO_BUNDLE included in Trading Strategy PyPi package, sorted by the market cap at the time of creation

Example usage:

# Print out all categories Coingecko has in our default bundle
from tradingstrategy.alternative_data.coingecko import CoingeckoUniverse

# Loads the default bundle included in PyPi package
coingecko_universe = CoingeckoUniverse.load()

# Prints out all categories found in this bundle.
# at the time of recording
categories = sorted(list(coingecko_universe.get_all_categories()), key=str.lower)
for cat in categories:
    print(cat)

• Then you can use this universe to build trading pair universe of a specific category, see categorise_pairs() for details
