Testing Quote Delivery Lag with a Shared Data Channel

Summary

This utility checks whether a lead-lag indicator reports a configured delay when quotes are relayed through a shared communication channel. The user runs the tester and indicator on the same instrument, selects a lag, and allows enough observations to accumulate; the indicator is expected to display that delay. The method is a controlled check of quote delivery timing rather than a trading signal or strategy.

Parameters specify the timer interval, the channel type, and the channel’s data source. The channel can use a CSV file in a common terminal files location or terminal global variables for bid and ask values; the selected mode determines which source fields must be supplied. The document gives no measured timing accuracy, latency distribution, or guidance on synchronization and file-update behavior. Results depend on the chosen communication path and environment, so the check establishes only whether the setup reflects the deliberately introduced delay under the conditions tested.

Key ideas

• Run the tester and lead-lag indicator on the same instrument and communication channel to check a known delay.
• Allow sufficient data to accumulate before comparing the displayed lag with the configured delay.
• Quotes can be passed through a shared CSV file or terminal global variables.
• Timer interval, channel mode, data source names, and injected delay are configurable inputs.
• The description reports no accuracy benchmarks or evidence beyond the expected controlled check.
