High Volume Items: Runes, food, and potions are consistently traded in large quantities, offering reliable flip potential with lower margins.
Speculative Gear: Items like Torva, Justiciar, or volatile orbs show sporadic spikes, typically around PvM updates or Twitch-driven hype. Caution advised.
Skilling Supplies: Supplies like Mahogany planks or Gold ore fluctuate with skilling meta and double XP events. Watch for long-term stability or sudden dump-ins.
Profit vs ROI: High ROI does not always mean high profit. Focus on total margin times trade volume per limit.
Item Limits: Items with low limits like dragon warhammer or volatile orb offer big margins but require babysitting for flips.
