I'm trying your tool, but I found a lot of exagerately wrong prices, in many occasions.
Today I found Semiconductors sold @ 6,569 Cr in a distant system (exciting, so I made the travel) while actually the correct price was 736 Cr when I got there. Totally useless. Same yesterday for another couple of commodities, while the ones of today were missing, so apparently they are a new entry.
How does this happen? Maybe something wrong with OCRs or just jokes?
General rule is if it sounds too good to be true, it probably is! Just use common sense.....you are unlikely to find a commodity profit per ton of more than around 2000cr (rare commodities aside), so just avoid anything like that.
For me, I have unfortunately got myself stuck in a rut.....I have found possibly the most profitable route in the fewest jumps possible, so going elsewhere is pointless, so I'm stuck in a grind of 2 jumps, dock, 2 jumps, dock, rinse and repeat....I have searched elsewhere, but nothing gives me the kind of round trip profit I'm getting right here.....I'm making 2040cr profit per ton within a 25Ly distance, which I can do in 2 jumps fully loaded with 104 tons.
I'm sure there are more profitable tonnages, but a longer distance, but this route is netting me a decent return trip profit, which can be tough to find.
I'm sure there is someone about to jump on me and argue they have better however. ;-)
