Would it be possible to set a power or logarithmic curve to the item pricing, along with a cap? For instance, if I want the price for diamonds to max out at 0 stock at the cost of 10,000 each, and minimum at 100 when its at 100 stock, but curve using a power function, so the price raises slowly at first, but faster at the end? This was a feature used in the old DynamicMarket mod, if you want to have a reference to look at.
