Sources and Limitations of Foreign Exchange Order Flow Data

Article Quant Q&A · Author: nisha

Summary

The document surveys possible sources for aggregated foreign exchange order-flow and volume data, including broker statistics, commercial providers, industry surveys, and settlement-system data. It explains a central limitation: spot FX is decentralized, and brokers may not share client flow because it can reveal internalization practices. Broker samples can also differ because routing and liquidity-provider arrangements vary. Community account statistics may offer a view of retail activity, while institutional volume surveys and settlement data provide broader but still incomplete coverage. One answer characterizes settlement-platform data as covering about half of global turnover and says its order-flow series is limited to spot trades. The recommendations vary in frequency, market segment, access, and cost, so they are not interchangeable measures of the same activity. The discussion is a list of leads rather than a systematic data audit; it does not establish current availability, historical depth, methodology, or comparability for every source.

Key ideas

  • Spot FX is decentralized, making comprehensive order-flow data difficult to obtain.
  • Brokers may withhold client flow because it can reveal internal trading and routing practices.
  • Retail account aggregates and institutional volume surveys measure different parts of the market.
  • Settlement-platform data can provide broad coverage but does not represent the entire FX market.
  • Potential sources differ in access, frequency, historical coverage, and market segment.

As Joshua mentioned, spot fx is decentralized. Furthermore, brokers (broker dealers) are reluctant to share their order-flow, mainly because it would likely reveal they are running a partial/full b-book (aggregation or internalizing client trades). This has become a sensitive topic in retail trading circles due to the temptation of dealers to 'trade against you' or manipulate your trades, especially if they suspect you are an well-informed trader. Even with an A-book, the order flow is still variable across brokers (as aggregation can go through several liquidity providers before reaching its final destination).

The best place to get as close to real time statistics on [retail] fx order flow would be MyFxBook community outlook. They sample volume from all their real [verified] trading accounts that connect to them to track statistics.

More comprehensive surveys of daily volume from the institutional side: Reuters FX Spot Volumes and ICAP Monthly Volume Data

The most comprehensive place that keeps track of nearly all daily foreign exchange notional volumes on a regular basis are the Bank for International Settlements (BIS) Semi-annual and Triennial surveys. When you here a broker advertise "forex does 4+ trillion dollar a day in volume, BIS is where they get those stats from.

Other honorable mentions:

- Integral FX TradeVault. A paid service, but integral is one of the larger aggregators in the industry.

- LMAX Exchange. They do not publish their daily volumes yet to the general public, but being the first transparent 'exchange' for spot forex (no last look order book), it will be interesting to see the related statistics from their order flow as they become a larger player.

- ForexMagnates . Many of the larger players and brokers from around the world do post their individual monthly volumes within a few days after the previous month closes.

- FXCM Real Volume and Transactions indicators. FXCM is a large player in the retail world as well as institutional, and has a lot of combined order flow, although the indicator is supposed to only do retail order flow from fxcm customers only.

More and more brokers will begin posting their order flow as the industry encourages more transparency. Post Dodd-Frank/post LIBOR manipulation regulations encourages more institutions to do accurate trade reporting for OTC products, so real time or more frequent volume data is just the next logical step.

CLS, the global payment-versus-payment FX settlement platform provides aggregated data through Quandl. CLS doesn't cover the entire market but settles about half of the global the FX turnover (for its membership across different trading platforms). The order flow data is provided for spot trades only.

Hope that helps. S

Why don't you try

http://www.bankofengland.co.uk/markets/Pages/forex/fxjsc/default.aspx http://www.ny.frb.org/markets/foreignex.html http://www.aciforex.org/

but the thing about FX order flow is there are so many order types: prices/quotes, natural flow, hedging, to mention just a few.
