What are Darvas Custom Indicators?

Darvas Custom Indicators let you write your own technical analysis scripts in JavaScript and render them directly on your charts. The API is intentionally Pine Script-shaped so seasoned TradingView authors feel at home, while keeping the full power of JavaScript: real loops, real closures, real if/else. 
const len = input.int("Length", 14);
const src = input.source("Source", "close");

plot("MA", null, { color: "#22c55eFF", linewidth: 2 });
plot("Hist", null, { color: "#a78bfaFF", style: "histogram" });

onBar(() => {
  const ma = ta.sma(src, len);
  plot("MA", ma);
  plot("Hist", ctx.close() - ma);
});
