The problem

Unlike all the other chains, Arbitrum contains no ticks information in its subgraph. One cannot calculate the liquidity in each tick that way.

Why is that? How can that be fixed?

Which subgraph?

I've been using https://api.thegraph.com/subgraphs/name/ianlapham/arbitrum-dev for a while without any ticks information, but then I noticed that https://info.uniswap.org/ is using this subgraph: https://api.thegraph.com/subgraphs/name/ianlapham/arbitrum-minimal

So I switch to that.

I also see something strange there; it seems all the liquidity on Arbitrum on the website is spread in a very strange way and probably incorrect as the sub-graph API returns zero ticks:

are there any plans to fix it?
