sort all markets by increasing fees, then iterate from lowest fee upwards;
sort within each fee tier by volume, discarding low-volume tail of quiet markets;
once the pool is narrowed down sufficiently, subscribe to websocket feed of trades;
estimate profitability, winner gets announced once per day
this is all without actually moving money, only listening to the data; then maybe once per week, ... decide whether any of the daily winners seem lucrative enough to justify LPing some dubious market
Revisiting an old metaphor, this should rank the surveyed markets from "Red Ocean" to "Blue Ocean", obviously not recommending that any liquidity be deployed towards the former.
