Monitoring Exchange API Availability with Concurrent Ticker Polling
Summary
This document describes a monitoring utility that polls ticker endpoints across multiple exchanges concurrently. It records whether each request returns data, keeps a rolling sample for each exchange, and reports the share of successful responses as an availability measure. The sampling interval and sample count are configurable.
A chart compares availability with last-traded prices, while a status table displays bid, ask, last, high, low, and volume fields. The code includes retry handling for incomplete asynchronous calls, status updates for pending requests, and a command to clear logs. This is operational monitoring rather than a trading strategy: it does not define entries, exits, or performance tests. Its availability estimate reflects successful ticker responses within the selected sample, so it does not establish broader exchange reliability, execution quality, or order-routing performance.
Key ideas
- Concurrent ticker requests let the monitor collect data from multiple exchanges in parallel.
- Availability is estimated as the fraction of sampled requests that return ticker data.
- A chart and status table show availability alongside market prices and ticker fields.
- The measurement is limited to ticker response success and does not assess trading execution.
