1. Hand-made bars (from Monday 8 January 2024, prices in pips above 1.1000)
A. the base buy: order block 12-17, gap 17-23 touching it -> entry 23, stop 16, target 37; aggressive: filled at 23 in bar 16, target in bar 17; conservative: shift = bar 17 closing above 25 -> entry at the open of bar 18 (37)
  [ok] setup at bar 14, origin 12, entry 1.1023, stop 1.1016, target 1.1037
  [ok] aggressive: 1.1023 -> 1.1037 (target), 1.8571 R
  [ok] conservative: entry 1.1037 at the open of bar 18, target 1.1079; reference identical

  [ok] order-block entry 1.1017, 1.8333 R; reference identical
C. a sweep closing back on its third bar (sweep low 12 on bar 12), a touching gap 15-16 and a higher one (17-23) not used; D. a breakdown (no close back above 15 within 3 bars): no buy
  [ok] setup at bar 15, entry 1.1016, 1.5000 R; reference identical
  [ok] breakdown: no buy setup; reference identical
E. a new low (11.5) before the break of structure voids it; F. the break of structure after 36 bars: no buy; G. equal lows (bars 3 and 4): no swing low, no buy
  [ok] new low: no buy setup; reference identical
  [ok] break of structure 38 bars after the origin: no buy setup; reference identical

  [ok] stop first: -1.1429 R; reference identical
  [ok] fill at 1.10225, 2.0769 R; reference identical
J. the weekend: a trade still open at the last minute before it closes there; K. no entry in the last hour before it (the fill comes after the weekend)
  [ok] exit at the weekend close 1.1024; reference identical
  [ok] bar 16 is inside the last hour: filled after the weekend at 1.1023; reference identical
L. conservative: the stop (16) reached before the shift -> no trade; M. no close above 25 within 12 bars -> no trade; N. expiry: the zone reached 290 bars after the break -> no trade

O. a newer setup replaces an unfilled one: the first buy (entry 23) is never reached; a second sweep (low 26 under the swing low 27 of bar 18) and a break above 35 form a new buy (entry 33), which is filled
  [ok] setups at bars 14, 24; the one trade at 1.1033; reference identical
