Snapshots
How it works
- Signals print only after the candle closes (barstate.isconfirmed), so they do not repaint.
- BUY needs a fast-over-slow EMA cross while price is above the Trend EMA; SELL is the mirror image.
- Create an alert on "EMA Trend Signals" and pick Buy or Sell, set to Once Per Bar Close.
Settings
| Setting | Default | What it does |
|---|---|---|
| Fast EMA | 9 | Short-term momentum line |
| Slow EMA | 21 | Crossover reference line |
| Trend EMA | 200 | Only trade in this direction |
