Series Architecture: Bar-Index Lookbacks (`close[1]`) & Warmup Guards
Understanding how rolling time-series buffers evaluate bar-by-bar without look-ahead leaks or NaN propagation.
Edge-Triggered Events (`crossover`) vs. Level-Triggered States (`>`)
Combining state filters (`close > ema200`) with edge triggers (`crossover(rsi, 40)`) to prevent duplicate entries.
