BSS Value Index

Trading multiple smaller-value items for a lesser number of higher-value ones.

Because you're asking for the convenience of fewer, larger items, the person accepting the trade generally expects you to slightly overpay (OP) — this is normal and expected in UP trades.

⚠ Common misconception: UP does not mean you're gaining value — it refers to item count, not profit.

The inverse of upgrading — trading one higher-value item for multiple smaller ones.

When downgrading, you should require an overpay from the other person. Since you're breaking up a single valuable item into many smaller pieces, the other party benefits from the convenience and should compensate accordingly.

⚠ Common misconception: DG does not mean you're losing value — it's about item count, not profit.

Giving more value than an item's listed average. This increases the likelihood the other person accepts your trade.

Overpaying is expected in UP trades and when chasing high-demand items — the extra value is the "convenience tax" you pay to acquire something specific.

The inverse of OP — offering less value than an item is listed for. Most experienced traders will decline an LB offer.

Occasional LBs happen when someone misjudges values or is testing a desperate seller, but consistent lowballing damages your reputation in the trading hub.

Small stickers added to a trade offer to balance the value gap when your main offer is slightly below what the item is worth.

Adds are the standard way to close the difference in any trade without needing to find an exact value match. Common adds include Star Signs, Lanceolate Leaves, and other low-value stickers.

💡 This tool's Calculator will suggest adds automatically when you're slightly under value.

Demand reflects how frequently an item is requested and traded in the trading hub. A high-demand item appears in the "Looking For" section far more often than others.

Important: Demand and value are independent. A high-demand item isn't necessarily worth more — but it may be easier to trade away, and people sometimes inflate prices on demand items to exploit hype.

💡 This tool's 📊 Demand sort mode re-orders everything by demand frequency instead of value.

In BSS trading, "Rare" describes an item with very few copies in existence, or one that almost never appears in the trading hub — regardless of its value tier.

Rare items are often limited or seasonal — obtainable only during a specific event or quest that no longer runs. Because supply is permanently capped, these items tend to hold or increase in value over time.

⚠ Never trash limited or seasonal items — their scarcity makes them permanently valuable even if their current listed value seems low.

A trade where both sides offer approximately equal value according to bssmvalues.com. Neither party is gaining or losing value in the exchange.

Most experienced traders aim for fair trades or slight OPs. The community primarily uses the value calculator to verify trades, so being within ~5% of listed value is generally considered acceptable.
