LiveMACEBench evaluates financial agents in persistent paper-trading accounts using live market data. It compares returns across matched configurations with decision traces that show whether tools, memory, rules, and specialist agents were used. In tool-use comparisons, return rankings reversed 21 times versus zero for Tool Call Score across 180 comparisons. This measures one approximately 30-day trajectory, not real-money performance.
