portfolio-rebalance
ActiveTool of The Stall
declared in 4.82.0
Pure-math portfolio rebalancing calculator. Given current holdings (asset names and their current USD values) and target allocations (percentages summing to 100), returns the exact buy/sell dollar amounts needed to reach target weights. Handles partial rebalancing with a drift threshold. No external API — deterministic and instant. Useful for DeFi agents, robo-advisory flows, and automated rebalancing triggers.
