How the flip loop works
Every item on the Currency Exchange trades on two markets: a chaos pair and a divine pair. When their implied prices diverge, a full loop is profitable before fees — D→C→item→D: your divines buy chaos, the chaos buys the item, and the item sells back for more divines than you started with. D→item→C→D is the same loop run the other way (buy the item with divines, sell it for chaos, convert back to divines).
The exchange charges gold per trade (scaling with trade value), which this board cannot fetch — no public API exposes gold fees. A loop is 3 trades, so treat small percentages as break-even and prioritise volume so your orders actually fill. Rates are ~5-minute snapshots of filled trades, not a live order book.
Bid/ask gaps: inside a single pair the in-game order book also has a buy/sell gap that no public API exposes — wide-gap items (often low-volume ones) can pay far more than the loop % shown here if you post orders on both sides and wait. Use the volume column as a fill-speed proxy: low volume = wider gaps but slower trades. Check the in-game book before committing large capital.
