# Get Large Trader Positions

> Positions of the authenticated clearing member that meet the CFTC large-trader reporting levels for a settlement day (17 CFR 15.03(b); each row's reportable_threshold is its market's level), plus exit-day positions that were reportable on the prior settlement day and are now below the threshold. Members with reportable positions are subject to their own CFTC Part 17 large-trader reporting obligations; this endpoint provides the position data needed to meet them. Empty when no positions meet the reporting levels and no prior-day reportable positions need exit reporting. See the CFTC's Large Trader Reporting Program (https://www.cftc.gov/IndustryOversight/MarketSurveillance/LargeTraderReportingProgram/index.htm) and reporting levels at 17 CFR 15.03 (https://www.ecfr.gov/current/title-17/chapter-I/part-15).
