This curriculum spans the technical and operational complexity of a multi-workshop program focused on building and maintaining a production-grade market data platform, comparable to the internal capability programs run by electronic trading firms and financial data providers.

Module 1: Defining Data Requirements and Market Data Sources

  • Selecting between exchange-direct feeds, commercial data vendors, and consolidated data providers based on latency, cost, and coverage needs.
  • Mapping required financial instruments (equities, options, futures) to available data source APIs and feed formats (e.g., ITCH, FIX/FAST, binary vs. JSON).
  • Evaluating real-time vs. delayed data licensing agreements and compliance with redistribution restrictions.
  • Designing schema for ticker universes that supports dynamic additions, delistings, and corporate actions.
  • Assessing time zone handling strategies for global market data ingestion across NYSE, NASDAQ, LSE, and TSE.
  • Implementing fallback mechanisms for primary data feed outages using secondary vendors or historical replay systems.
  • Documenting metadata standards for ticker attributes (ISIN, CUSIP, SEDOL) and exchange mappings.
  • Integrating reference data (e.g., symbology crosswalks, corporate actions) from third parties like Bloomberg or Refinitiv.

Module 2: Ingestion Architecture for High-Velocity Market Data

  • Choosing between push-based (WebSocket, multicast UDP) and pull-based (REST polling) ingestion models based on throughput and jitter tolerance.
  • Configuring Kafka topics with appropriate partitioning schemes (by exchange, symbol, or asset class) to balance parallelism and ordering.
  • Implementing protocol decoders for binary market data formats (e.g., NASDAQ ITCH 5.0) with zero-copy parsing for low latency.
  • Designing ingestion pipelines with backpressure handling to prevent data loss during downstream system congestion.
  • Setting up monitoring for message sequence gaps and heartbeat timeouts in real-time feeds.
  • Deploying edge collectors in co-location facilities to minimize network round-trip time for time-sensitive strategies.
  • Validating payload integrity using checksums and message sequence numbers at ingestion points.
  • Normalizing timestamp sources (exchange timestamp vs. system timestamp) with precision to microsecond or nanosecond level.

Module 3: Data Storage and Schema Design for Time Series

  • Selecting columnar storage formats (Parquet, ORC) vs. time-series databases (InfluxDB, QuestDB) based on query patterns and retention policies.
  • Partitioning historical data by date and clustering by symbol to optimize range scans for technical analysis.
  • Implementing tiered storage strategies with hot (SSD), warm (HDD), and cold (object store) layers for cost-performance balance.
  • Designing schemas that support tick-level, minute-bar, and daily aggregates with schema evolution capabilities.
  • Choosing between row-level and batch-level compression for tick data based on access frequency and I/O patterns.
  • Enforcing data retention and purging policies in compliance with regulatory and audit requirements.
  • Indexing high-cardinality symbol dimensions without degrading write performance in distributed stores.
  • Implementing point-in-time snapshots for backtesting consistency across mutable corporate actions.

Module 4: Stream Processing and Real-Time Analytics

  • Developing Flink or Spark Streaming jobs to compute real-time VWAP, bid-ask spread, and volume surges.
  • Configuring watermarking strategies to handle late-arriving market data messages within acceptable tolerances.
  • Implementing sliding and tumbling windows for calculating moving averages and volatility metrics.
  • Designing stateful processing to track order book depth changes and detect spoofing patterns.
  • Optimizing serialization (e.g., Avro, Protobuf) for low-latency stream processing pipelines.
  • Integrating CEP (Complex Event Processing) rules to flag unusual trading activity or circuit breaker conditions.
  • Scaling stream processors horizontally while maintaining exactly-once semantics across failures.
  • Validating output accuracy by replaying test datasets with known expected results.

Module 5: Data Quality, Validation, and Anomaly Detection

  • Establishing data quality SLAs (e.g., max latency, completeness, accuracy) for each data product.
  • Implementing automated checks for out-of-range prices, zero-volume ticks, and duplicate sequence IDs.
  • Designing reconciliation processes between primary and backup data sources to detect silent failures.
  • Using statistical process control to identify anomalies in volume or volatility distributions.
  • Flagging stale instruments that have not reported trades for configurable time thresholds.
  • Correlating feed health metrics with external market events (e.g., exchange maintenance, news spikes).
  • Logging and routing data quality violations to alerting systems and data stewards.
  • Creating synthetic test data to simulate edge cases (e.g., flash crash, halts) for pipeline validation.

Module 6: Governance, Compliance, and Auditability

  • Implementing data lineage tracking from source feed to derived analytics using metadata tags and provenance logs.
  • Classifying data sensitivity levels (e.g., real-time quotes vs. historical closes) for access control.
  • Enforcing role-based access controls (RBAC) on data stores and APIs based on regulatory domains.
  • Logging all data access and modification events for audit trail compliance (e.g., MiFID II, Reg SCI).
  • Managing data retention and deletion workflows in alignment with legal hold policies.
  • Documenting data transformations and business logic for regulatory review and model validation.
  • Integrating with enterprise data catalogs to expose metadata to compliance officers and data owners.

Module 8: System Monitoring, Alerting, and Operational Resilience

  • Deploying end-to-end latency probes to measure data path delays from exchange to analytics layer.
  • Setting up real-time dashboards for feed health, ingestion rates, and processing lag metrics.
  • Configuring alert thresholds for abnormal conditions (e.g., missing heartbeats, spike in error rates).
  • Implementing automated failover between primary and backup data centers for high availability.
  • Conducting regular disaster recovery drills using data replay from persistent message queues.
  • Rotating and archiving logs from ingestion, processing, and storage layers for forensic analysis.

  • Securing data endpoints using OAuth2, API keys, and mutual TLS based on consumer type.
  • Supporting batch data exports in standard formats (CSV, Parquet) for offline analysis and regulatory reporting.
