Forum - NPC Resell glitch?

Kadalyn

We don't know the formula of sale prices under 10k (I think it's between 1k and 10k or something like that), because it's some sort of curved scale up to 10k where 10k+ is just price/10.

For that reason, the sale price for such items has to be entered manually. If someone wants to figure out the formula that would definitely be awesome (I can add it to the template if they're uncomfortable doing so).

Oooh, that's weird. So would that mean for under 10k items, we'd have to check in-game for the sale prices?

Simply put, yes. You can attempt to sell it then cancel the transaction to get the price.

I took a look to double-check, this is what we have currently:

{{MouseoverBox|{{#if:{{{SellPrice|}}}|{{formatnum:{{{SellPrice}}} G}}|{{#if:{{{BuyPrice|}}}|{{#ifexpr:{{{BuyPrice}}}>=10000|{{formatnum:{{#expr:{{{BuyPrice}}}/10}}}} G|{{#ifexpr:{{{BuyPrice}}}=0|0 G|{{#iferror:{{#expr:{{#if:{{{Resell|}}}|{{{Resell}}}|?}}}}|? G[[Category:NeedMarket]]|{{formatnum:{{{Resell}}}}} G}}}}}}|}}}}|BuyPrice: {{ifempty|{{{BuyPrice|}}}|-}} G<br />SellPrice: {{ifempty|{{{SellPrice|}}}|-}} G<br />Predicted SellPrice: {{formatnum:{{#ifexpr:{{{BuyPrice}}}<=100|{{#expr:{{{BuyPrice}}}/2}}}}{{#ifexpr:(100<{{{BuyPrice}}}) and ({{{BuyPrice}}}<=1000)|{{#expr:({{{BuyPrice}}} / (2 + ({{{BuyPrice}}} - 100) * 2 / 900))}}}}{{#ifexpr:(1000<{{{BuyPrice}}}) and ({{{BuyPrice}}}<=10000)|{{#expr:({{{BuyPrice}}} / (4 + ({{{BuyPrice}}} - 1000) * 6 / 9000))}}}}{{#ifexpr:{{{BuyPrice}}}>10000|{{#expr:{{{BuyPrice}}}/10}}}} G}}}}

This says (BP = BuyPrice):

• If the BP is over 10000; resell price is BP/10
• If the BP is 0 so is the resell price
• If the BP is under 100; we think the resell price is BP/2
• If the BP is between 100 and 1000; we think the resell price is BP / (2 + (BP - 100) * 2 / 900))
• If the BP is between 1000 and 10000; we think the resell price is BP / (4 + (BP - 1000) * 6 / 9000))

I believe these latter parts are just approximations rather than attempts at the real formula.
