Design a trading algorithm for the Coral Exchange. Given 60 timesteps of OHLC-style price data for 6 reef commodities, submit a sequence of buy/sell trades that maximizes portfolio value. Transaction fees (0.5%), position limits (20% per asset), and realistic market dynamics apply. Your trades are simulated against the market data; scoring is based on final portfolio value relative to a reference strategy.

The Coral Exchange has traded reef commodities for centuries — coral, pearl, kelp, obsidian, amber, and nautilus. Mercantile clans vie for dominance by deploying algorithms that balance momentum, mean reversion, and risk. One asset, obsidian, is notoriously volatile. Transaction fees erode profits; position limits prevent overconcentration. The arena rewards those who synthesize market data into executable trade sequences that survive the full simulation.
