  description: >
    V24 → V43: changes the ORB window from 5-min to 30-min.

    V24 uses the first 5-min candle (9:30-9:35 ET) as the opening range.
    V43 uses the first 30-min window (9:30-10:00 ET) as the opening range.

    Hypothesis: a 30-min ORB gives more time for:
    (a) False breakouts to resolve — early spikes and fades complete within the window
    (b) Institutional orderflow to participate — large orders execute over 30 min
    (c) The true range to establish — less noise in the high/low

    Risk: entering later (at 10:00+) rather than 9:35 means:
    (a) Less time in trade, exit pressure before 4 PM
    (b) May miss some early morning momentum

    All other V24 params unchanged.

    Gates (200d): Return ≥ +98.8% (V24 +94.8% + 4pp), DD ≥ -11.79%, Sharpe ≥ 2.93
    Gates (400d): Return ≥ +166.1% (V24 +162.1% + 4pp), DD ≥ -14.20%, Sharpe ≥ 2.52
