With least possible latency (sub-microsecond)
Without jitter even during microbursts of activity
 Algo-Logic’s CAPI-enabled order book
•
•
•
Receives live, level 3 market data feeds
Builds order books in FPGA logic on CORSA card
Sends level 2 snapshots to processor threads
 Advantages
•
Provides immediate and actionable BBO for trading

Knows the structure
i.e. knows the offsets,
needs to know only
