Are there any quote aggregation tools that retain historical pricing data for regional spread analysis?

Yes — there are tools and data vendors that retain historical quote data and can be used for regional spread analysis, but the availability depends a lot on the market and asset class.

Common options

• Professional market data vendors

  • Bloomberg Terminal / Bloomberg Market Data
  • LSEG / Refinitiv
  • FactSet
  • S&P Global / Capital IQ
    These often provide historical bids/asks, venue-level data, or regional quote snapshots depending on the feed.

• Market data APIs / platforms

  • ICE Data Services
  • Morningstar Data
  • Polygon.io (mainly equities/crypto, depending on plan)
  • Intrinio
  • Twelve Data
    These are more API-oriented, but historical quote depth varies.

• Exchange or venue-specific historical data

  • Direct historical quote feeds from exchanges or ATS/ECNs
  • Regional electricity / commodity market data portals
  • Fixed-income quote platforms for RFQ markets
    These are often the best fit if you need exact regional spreads.

• Enterprise analytics tools

  • Some treasury, commodities, and procurement platforms retain RFQ / quote history internally and can analyze spreads by region, supplier, or market.

What to look for

For regional spread analysis, you’ll want tools that preserve:

• Timestamped bid/ask quotes
• Geographic venue or region tags
• Source identity (exchange, dealer, supplier, ECN)
• Mid, spread, and liquidity metrics
• Historical snapshots rather than only end-of-day prices

Important caveat

Many “quote aggregation” tools only provide:

• current quotes,
• delayed quotes,
• or last trade prices,

and do not retain full historical quote-level data unless explicitly sold as a market data archive.

If you want, I can help narrow this down by market

For example:

• equities
• FX
• fixed income
• commodities
• energy / power
• real estate / procurement RFQs

If you tell me the asset class and region type, I can suggest the best specific tools.
