The relationship between the buy cost and the sell price of an alloy or item in the market can be approximated to a linear relationship. The profit gained from buying and selling is then a quadratic function creating a parabola. Buying and selling 0 items will create profit of 0. Buying and selling x items so that the buy cost is equal to the sell price will also create profit of 0. The midpoint between 0 and x will create max profit due to the symmetry of the parabola shape. In other words x/2 is the optimal amount.

Profit max condition is marginal revenue = marginal cost

I’m pretty sure there’s more items between (0,x/2) compared to (x/2,x) so your way is both unintuitive as well as inaccurate. The method described by Balmybrz is (much) easier to use in-game as well as factually correct.

My way is unintuitive because it requires no intuition. It is dividing by two. It is foolproof. It is accurate enough for what I have. Honestly I have no idea where to see marginal revenue and marginal cost so my way is better for me is what I mean to say. Stop plotting my downfall by blowing smoke into my brain. I know myself. But do you?

I think we know you better than you do, and that you don't really know yourself as well as you think you do.

I know I could spend 132m on copper bars before the cost of each copper bar equaled the sell price of 214. I bought 66m and after I did the price rose to 214 so I just assumed that my way worked. Maybe not I don’t know anymore. I don’t know what to think no more man. Get of mi head.
