Bid smart in Blade & Soul

Smart bid allows you to tell how much you should bid for an item in a dungeon according to BnS market price. You have two options:

• you want to keep the item for yourself
• you want to make profit and sell it on market (we deal with this)

Note that the results depends on the current market price, the current number of players in your party (remove party members who left), and the item quantity. Market fees plays a role in the second case and we take 5% fee as approximation (2% presale + 3% postsale commission).

The maths behind are simple. The profit you would make on market would be \((1 - market\_fees) \cdot current\_market\_price - bid\). The money you would get from the bid in the party would be \(\frac{bid}{num\_players - 1}\)

We want to minimize \(bid\) so that $$ (1 - market\_fees) \cdot market\_price - bid > \frac{bid}{num\_players - 1} $$ in other terms $$ bid < (1 - market\_fees) \cdot market\_price \cdot \frac{num\_players - 1}{num\_players}$$
