1. Hand-worked bars (4-hour slots from 1 Jan 2024)
A. HA values: bar 1 (100/110/90/105): HA open 102.5, HA close 101.25, red; bar 2 (105/120/104/118): HA open 101.875, HA close 111.75, HA low 101.875 = HA open -> green, no lower wick; bar 4 (124/124/100/101): HA open 113.90625, HA close 112.25, HA high 124 -> red with an upper wick; bar 5 (101/101/95/96): HA open 113.078125, HA high = HA open -> red, no upper wick
  [ok] bar 1
  [ok] bar 2 green, no lower wick
  [ok] bar 4 red with an upper wick
  [ok] bar 5 red, no upper wick
B. HA-NOWICK: long at the open of bar 3 (118), out at the open of bar 5 (101) after the red bar 4 (it has an upper wick, so no short); short at the open of bar 6 (96) after the no-wick red bar 5; closed at the last close (97) at the end of the data
   HA-FLIP: long at 118 on the colour change of bar 2, reversed short at 101 (open of bar 5), closed at 97
  [ok] HA-NOWICK: -14.500%, -1.142%
  [ok] HA-FLIP: reversal at the same minute
  [ok] the signal of bar 2 is executed at the first minute of bar 3
  [ok] reference identical (3 variants)
C. a 4-hour slot with only 100 minutes after bar 2: no HA bar, the chain continues; the signal of bar 2 executes at the open of that short slot
  [ok] short slot skipped; entry at 200; reference identical
D. the 200-bar average: a steady rise gives a no-wick green bar every time; HA-NOWICK is long from the open of bar 3, HA-NOWICK-200 only from bar 201 (the first with 200 closes, above their mean); a steady fall gives the shorts the same way
  [ok] entries 1002, 1200, 2998, 2800
  [ok] reference identical
E. no signal is taken on a bar that ends before 1 Oct 2017
  [ok] the bar ending at 00:00 on 1 Oct is the first live one
