Ted's Diamond Hunt 2 custom market user interface
I have fixed the market table not displaying correctly, sorry for delay on this, I was away for the weekend.
I'm not sure about the essence profit being wrong, as you described it sounds wrong but I have checked my math and my numbers for my levels and I am seeing correct results, check you are on the latest version of the script as I think in the past there was a bug in the essence profit math but this was fixed.

When I press the Infinity button, I get the vanilla market browse.
The essence potion profit seems to be wrong. It says it costs 600k for a potion, with an average essence of 1 per potion, and a profit of 300k. But each essence costs 300k so you seem to be missing a subtraction in your calculations.
