PASS hand case: Coppock(1, 1, 3) = [-, -, -, 13.3333, 6.6667, 13.3333, 6.6667, 13.3333]
PASS hand case: signals bull@5 (turns up after 13.33 -> 6.67), bear@6, bull@7; none before the curve has three values
PASS a repeated signal in the same direction (a tie in the curve) is ignored: [0,1,0,1,1,2] -> bear@2, bull@3 only
PASS default settings: ROC 14 + ROC 11, WMA 10, weights divided by 55

Real data (no results printed):
  (ES: 39787 hourly bars; 5963 signals; first signal on bar 26; signals alternate: true)
PASS the engine's Coppock curve matches a naive recomputation to 1e-9 on the real bars - max diff 0.0e+0
PASS the engine's signals equal the naive signals bar by bar
PASS signals alternate and the state series flips exactly at the signals
PASS CC-L-N: engine = independent reference on the same signals, trade by trade
PASS CC-L-S: engine = independent reference on the same signals, trade by trade
PASS CC-L-T1: engine = independent reference on the same signals, trade by trade
PASS CC-L-T2: engine = independent reference on the same signals, trade by trade
PASS CC-L-T3: engine = independent reference on the same signals, trade by trade
PASS CC-L-T123: engine = independent reference on the same signals, trade by trade
PASS CC-LS-N: engine = independent reference on the same signals, trade by trade
PASS CC-LS-S: engine = independent reference on the same signals, trade by trade
PASS CC-LS-T1: engine = independent reference on the same signals, trade by trade
PASS CC-LS-T2: engine = independent reference on the same signals, trade by trade
PASS CC-LS-T3: engine = independent reference on the same signals, trade by trade
PASS CC-LS-T123: engine = independent reference on the same signals, trade by trade
PASS the control machinery runs on the real bars for all 12 variants (3 smoke runs)

SELF-TEST PASSED: every check passed (6 s). cc_run.js may now be pointed at the data.
