Extreme Z Scanner
Find S&P 500 stocks making a new Z-score record or currently beyond ±2. Use the original all-history ThinkScript logic or a rolling X-trading-day window.
252-day mode computes each rolling 252-day Z-score. Record-break filters compare today with the prior 252 rolling Z readings; the ±2 filters apply directly to today's 252-day Z.

Combined views: Highest / Lowest Only shows either record-break signal; Highest / Lowest Only & Z ±2 requires both a record-break signal and |Z| ≥ 2; Z ±2 Only shows |Z| ≥ 2; Z ±1.5 Only shows |Z| ≥ 1.5. A ticker can appear in multiple combined views when it satisfies multiple criteria.

All History preserves your supplied ThinkScript series calculation exactly.
ALL HISTORY
barCount = cumulative number of bars
mean_t = TotalSum(close)_t / barCount_t
variance_t = TotalSum((close - mean)^2)_t / barCount_t
Z_t = (close_t - mean_t) / sqrt(variance_t)
NEW LOWEST if Z_t < every prior Z
NEW HIGHEST if Z_t > every prior Z
Z ≤ -2 if Z_t ≤ -2
Z ≥ +2 if Z_t ≥ +2
Rolling X uses the most recent X closes for each bar's mean/std. The ±2 filters use that same selected rolling Z.
ROLLING X
mean_t = mean(last X closes)
std_t = population std(last X closes)
Z_t = (close_t - mean_t) / std_t
NEW LOWEST if current Z < minimum(prior X rolling Z readings)
NEW HIGHEST if current Z > maximum(prior X rolling Z readings)
Z ≤ -2 if current Z ≤ -2
Z ≥ +2 if current Z ≥ +2
