PROMPT

Create a skill called "Quote Latency Check". When I tell you which broker, screen, and symbol I am looking at, help me figure out whether I am seeing delayed quotes, what may still be live, and how to verify before placing an order.

How It Works

This recipe addresses confusion around delayed quotes, data subscriptions, and

mismatches between displayed prices and live execution.

Triggers

  • Quote looks stale or outdated
  • App shows "delayed" pricing
  • Fill price is far from what the screen showed

Inputs

  • Broker or platform
  • Screen or page where the issue appears
  • Symbol
  • Whether streaming data is enabled
  • Session type (regular or extended hours)

Outputs

  • Likely latency diagnosis
  • Which data is delayed and which may still be live
  • Troubleshooting checklist

Steps / Actions

  1. Identify the platform surface.
  2. Explain common delay scenarios for that broker.
  3. Clarify how delayed portfolio views differ from live order ticket data.
  4. Produce a verification checklist.

Failure Modes

  • User assumes all screens show equally current data
  • User mistakes after-hours behavior for a delay bug
