Ticks in V2? about docs

[Florian-S-A-W]

Hi @0xJepsen
This refers to the general trading term Tick Size and has nothing to do with what Uniswap calls "Ticks" in the V3 Protocol.
While the AMM model Uniswap uses is continuous, every Token has a discrete minimum unit. Lets look at ETH and its minimum unit Wei which is 10^(-18) ETH. You can't provide anything smaller than 1 Wei in liquidity to a Pair.
Let's imagine you deploy a Token with only 6 decimals like USDC with a very low supply. That could make one minimum unit of it worth a significant value, lets say 1000 USD. If you deploy a Pair with 10 units of this token, the minimum price ratio change you could achieve would be around 10% while the Pair has a liquidity of over 20.000 USD.
Obviously this is an exaggerated example but the same concept is true for any coin. By enforcing a minimum liquidity of 1000 minimum units of the Token, the initial Tick Size i.e. minimum price ratio change is always below 0.1%.

That makes sense, i think the way it is worded in the documentation is confusing since V3 has a very specific definition of a tick struct. Might be worth rewording to make more clear to users.
