Bullish/bearish divergence with confirmation on close.

// RSI divergence with two-bar confirmation.
let r = rsi(close, 14)
let bull = pivot_low(r, 5) and pivot_low(close, 5)
let bear = pivot_high(r, 5) and pivot_high(close, 5)
mark(bull, color: bull, label: "div+")
mark(bear, color: bear, label: "div-")
output bull or bear

Long on 20-day high, exit on 10-day low. Position-sized by ATR.

let hi = highest(high, 20)
let lo = lowest(low, 10)
let size = atr_position(risk_pct: 1.0, atr: atr(14))
if cross_up(close, hi[1]) { buy(qty: size) }
if cross_down(close, lo[1]) { sell_all() }

Anchored, session, and rolling VWAP plotted together.

let v_session = vwap(anchor: "session")
let v_anchor = vwap(anchor: bar(0))
let v_roll = vwap(window: 50)
plot(v_session, color: accent)
plot(v_anchor, color: bull)
plot(v_roll, color: warning)

Closes above 20-day high on +1.5× average volume.

for sym in watchlist("us-small-cap") {
  let hi = highest(high, 20)
  let v = sma(volume, 20)
  let hit = close > hi[1] and volume > v * 1.5
  if hit { yield sym }
}

Fires when RSI > 70 and the bar closes below its open.

let trigger = rsi(close, 14) > 70 and close < open
