Financial Information Forum Trade-Through Inquiry Tool

The purpose of this tool is to compare an execution to SIP quotes to determine if a potential trade-through exists. Enter the details of an execution and the desired quote window size below. The side is the one taken by the executing venue. The quote window surrounds the execution time to account for flickering quotes.

For each market center offering protected quotes, the most inferior price in force on the executing side within the quote window is selected and shown. If the trade price is inferior to the selected quote for any market center, a potential trade-through has occurred and the violated venues are colored orange.

Quotes are generally available from several months ago up to the previous business day.
