In many markets, traders’ demands for an asset are contingent on the price of that asset alone rather than on the price of all assets they trade. We present a model based on the uniform-price double auction which accommodates arbitrary restrictions on cross-asset conditioning, including asset-by-asset market clearing (demand for each asset is conditioned on the price of that asset) and a single market clearing (demand for each asset is conditioned on the prices of all assets). If suitably designed, markets with limited demand conditioning are at least as efficient as a single market clearing for all traders and assets.
