Examples

Minimal Pine snippets you can paste into Chart Script and adapt for live deploy.

SMA cross entries

//@version=5
strategy("SMA Cross", overlay=true)
fast = ta.sma(close, 9)
slow = ta.sma(close, 21)
if ta.crossover(fast, slow)
    strategy.entry("Long", strategy.long)
if ta.crossunder(fast, slow)
    strategy.entry("Short", strategy.short)

Multi-target with algo.levels

//@version=5
strategy("Levels demo", overlay=true)
if ta.crossover(ta.sma(close, 5), ta.sma(close, 20))
    strategy.entry("L", strategy.long)
algo.levels(sl = 50, tp1 = 100, tp2 = 200, qty1 = 50, qty2 = 50)

Script exit with strategy.close

//@version=5
strategy("Close on RSI", overlay=true)
rsi = ta.rsi(close, 14)
if rsi < 30
    strategy.entry("L", strategy.long)
if rsi > 70
    strategy.close("L")
