This is an extremely hard problem to solve tbh, since gossip is forever changing/influx (liquidity and movement of it is never static, nor are network fees), and to find the most highly profitable channels you need to find the gab between two groupings of the network nobody else has found. Also, you have to keep in mind closing/opening fees, how the liquidity is moving across the channels, not to mention the fact privacy is import so very few have a solid picture of liquidity flows across the network, only those running really large nodes or many highly connected nodes have an okay real time picture. Sophisticated analysis is required to create an algorithm that makes this profitable for many people using the same tools. People are working on this, or at least trying to solve the preliminary problems required at attempting a solid solution. What may seem simple from the outside has layers and layers of hidden complexity to get a solution that works and is scalable and profitable (or at least breakeven). There is certainly a need for this product, but it’s not easy is all.
