Methodology & interpretation
IDMM factors were available before each session and were derived from end-of-day (EOD) data. A portion of that EOD data was computationally audited against corresponding 1-minute intraday files. This report uses daily/EOD Open values to anchor the structural levels and daily/EOD Close values to evaluate closing outcomes. Level reaches and same-session ML1/MS1 reversals are identified using local 1-minute intraday data. Supporting charts display 15-minute OHLC bars. Structural statistics exclude April 29, June 17, July 29, and September 16, 2026, due to Fed meetings/calendar events. Closing percentages use sessions reaching the stated level. Reversal percentages use sessions reaching ML1 and/or MS1 and do not establish which level came first. Totals pool qualifying symbol-session counts rather than averaging symbol percentages. Level populations overlap, and correlated instruments are not independent observations. The published viewers display exported results without rerunning the research calculations.
Outcome percentages use sessions reaching the stated level. ML outcomes are measured separately: Close ≥ the reached level, and Close ≥ Open. MS outcomes are measured separately: Close ≤ Open, and Close ≤ the reached level. Level populations overlap; do not add level counts.
Directional sessions reach ML1 and/or MS1, counted once within each symbol. Reversals reach both ML1 and MS1. The reversal rate uses directional sessions as its denominator; it does not identify which level came first.
Totals pool qualifying counts, rather than averaging symbol percentages. The same date across two symbols counts as two symbol-sessions. Correlated symbols are not independent observations.
The summary CSV contains exported statistics. When provided, the Session Audit CSV contains the symbol-date records and their contributions to those totals; it is not a raw intraday bar file. Figures are displayed as exported; the public reader does not rerun the research calculations.
