OSRS Grand Exchange flipping guide
Tax-honest GE spreads, UKF fair-price signals, and how Demo mode differs from wiki Real-time Prices.
Open the GE desks
Start on the OSRS GE market desk for high/low with UKF context, then the flipping desk for ranked instant buy→sell spreads after the 2% GE tax (5m cap).
Tax is not optional
Margins after tax can invert a “wide” high/low spread. The desk applies the GE tax model so you do not chase pre-tax ghosts. Volume / gp/hr proxies help filter illiquid names.
Live vs Demo
Prefer OSRS Wiki Real-time Prices. If the API is unreachable or history is too thin, desks fall back to a labeled Demo series — never silently “Live.”
Skilling vs flipping
Herblore, crafting, fletching, and other skilling desks answer a different question (gp per action / xp). Use them when you are training; use flipping when you are rotating GE slots.
