Price to tick calculation

[adradr]

I am probably missing some point here, but after reading your article, still don't understand.

I copied a random position from the USDC/ETH 0.3% Ethereum mainnet pool. By simply running your price_to_tick function over this 1900 price it yields a totally different tick price. Can you please elaborate what am I missing here?

Thanks,
Adrian

EDIT: 0.05% -> 0.3%

GitHub wiped out my answer... Well, in short, you need to flip the price so it's the price of USDC in WETH (the price in a pool is the price of token 0 in terms of token 1):

math.floor(math.log(int(1e18 // 1900.79e6), 1.0001))
# 200820
