Exegy Liquidity Lamp Summary by Exchange

Detecting hidden order flow including iceberg orders and other institutional algorithmic orders is a trading signal that every serious investor should be paying attention to regardless of investment horizon.

Liquidity Lamp is from the Signum portfolio of real-time signals. It detects and tracks reserve orders on US stock exchanges. Liquidity Lamp Summary is a daily summary of reserve order buying and selling activity on a per-stock, per-market basis. This provides a focused view of informed investors who use iceberg orders to deftly move large volumes of shares and is far timelier than scouring quarterly Form 4 and Form 13F regulatory filings. Liquidity Lamp Summary can enhance the performance of a broad range of quantitative strategies including long/short strategies both on the individual symbol level as well as at the index level.
