Each source assigns importance differently (Finviz curates 1-3, Investing.com curates with bull icons, Fed events default to 'high' for FOMC/minutes/statements/Beige Book and 'medium' for everything else). The three roughly agree on the big releases. What to expect:
• 'High only' — only the headline-mover releases: NFP, CPI, FOMC decisions, ISM PMI, GDP, jobless claims, Michigan sentiment. Typical week: 5-15 rows. Best for AI agent context budgets.
• 'Medium and above' — adds tier-2 releases: ADP, retail sales, durable goods, building permits, factory orders, Fed speeches, manufacturing PMIs. Typical week: 30-60 rows.
• 'All importance levels' — adds Treasury auctions, EIA oil/gas inventory, mortgage indices, regional Fed surveys, statistical publications. Typical week: 100-200+ rows.
If unsure or you need the full picture, pick 'All importance levels' and filter downstream — sources are noisy in different ways.
