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