Systems and methods are disclosed herein that compute trading signals with low latency and high throughput using highly parallelized compute resources such as integrated circuits, reconfigurable logic devices, graphics processor units (GPUs), multi-core general purpose processors, and/or chip multi-processors (CMPs). For example, a liquidity indicator that indicates a presence of a hidden order for a financial instrument can be generated based on processing of streaming financial market data that operates to detect the existence of hidden orders within the financial market data.
