Tick-to-trade Latency
Tick-to-trade latency measures the total time elapsed from receiving a market data update (tick) to sending a corresponding trade order to the exchange. This critical performance metric is essential for high-frequency trading systems where microseconds can impact trading success.
Understanding tick-to-trade latency
Tick-to-trade latency represents the complete processing time of a trading system's decision cycle, encompassing multiple steps:
- Market data receipt and decoding
- Strategy computation and decision-making
- Order creation and encoding
- Order transmission
This metric is particularly crucial for high-frequency trading systems where competitive advantage often depends on processing speed.
Components of tick-to-trade latency
Network latency components
- Wire-to-wire processing time
- Port-to-port communication delays
- Socket-to-socket processing overhead
Processing components
- Market data normalization
- Strategy computation
- Risk checks
- Order generation

Impact on trading strategies
The tick-to-trade latency directly affects:
- Fill rates
- Slippage costs
- Market impact
- Competition effectiveness
Trading firms must carefully balance their technology investments against expected returns, considering both the costs of reducing latency and the potential benefits in trading performance.
