Execution latency

Delay between decision, order submission, and matching — with direct impact on price and fill quality.

On this page

Latency is dead time in which the market can move against you. On the Gold path it is monitored as an implicit infrastructure cost.

Gold path — Module: Professional execution. Part of gold-path.

Who this is for

  • Anyone running strategies sensitive to timing.
  • Anyone who notices a gap between click price and fill price.
  • Anyone using APIs, bridges, or multi-venue routing.

Prerequisites — Complete silver-path first (min.: market-order, slippage, active-management, position-sizing). Foundation: bronze-path.

In plain terms — Between your click and the fill, precious milliseconds pass. If the market runs, that delay becomes a concrete cost.


Practical optimisation

Measure end-to-end latency: platform, network, broker, exchange. Separate technical latency from human decision latency. Remove unnecessary hops and validate stability during high-volatility periods. Set execution fallbacks when latency exceeds a critical threshold. Link latency data to slippage and fill-ratio metrics.

Example — On a macro event average latency rises from 60 ms to 240 ms. Average slippage doubles and the strategy loses edge. With alternative routing and limit-first rules the degradation shrinks.

Card

  • Goal: reduce operational delay in sensitive phases.
  • Key inputs: order timestamp, ack, execution.
  • Warning sign: latency spikes during news.
  • Typical mistake: measuring only the local connection.
  • Practical action: periodic audit of the order path.
