Price calculation

• BP = final buing price
• SP = final selling price
• PoI = default price of item from TraderItemsPrices.json
• CoI = count of item in storage from TraderStock.json
• Dis = discount determined by player's reputation level. It is calculated on condition when sellingRatioMin != 0

if (stockCap == 0)

BP = PoI * (1 - Dis) * quantity * health

SP = PoI * (SellingRatioMin + Dis) * quantity * health

if (stockCap > 0)

PRICE = PoI - CoI * (((1 - BuingRatioMin) * PoI) / stockCap)

BP = PRICE * (1 - Dis) * quantity * health

maxSP = SellingRatioMax * PRICE

minSP = SellingRatioMin * PRICE

SP = maxSP - CoI * (maxSP - minSP) / stockCap

SP = SP * (1 + Dis) * quantity * health
