Understanding Market Statistics

The Market Statistics pages provide a summary of municipal securities transaction activity for all published trades disseminated by the MSRB for every trading day since May 2006. The information reflects trading activity at the end of each trading day as reported to the MSRB’s Real-Time Transaction Reporting System (RTRS). Trading data can be viewed for a single day or for a range of days. Market statistics may be updated for up to 20 days after the trade date to account for modifications, cancellations, trades reported late or any other changes to the underlying characteristics of the securities.

Trading data is not available for weekends and certain holidays. Dollar amounts are displayed in millions. Additionally, all amounts and percentages may not add up due to rounding.

A “mouse over” function displays underlying information and data for each graph when the cursor pauses or hovers over a particular area of the graph.

The statistics pages include the following information:

  • Trade Summary

  • Average Number of Trades

  • Average Par Amount

  • Par Amount and Number of Trades by Trade Size

  • Par Amount Traded for Most Active Sectors

  • Par Amount Traded by Remaining Maturity

  • Par Amount Traded Based on Source of Repayment

  • Par Amount Traded by Coupon Type

  • Most Active Municipal Securities
