What is ROC + SAR Alert?
ROC + SAR Alert is a two-in-one signal indicator for MetaTrader 4 and MetaTrader 5. It combines the Rate of Change (ROC) momentum reading with the Parabolic SAR trend flip, so instead of watching two separate tools you get a single, clear buy or sell arrow only when both line up.
How the Signals Work
- BUY / CALL arrow: the Parabolic SAR dots flip below price while the Rate of Change is above zero — momentum and trend agree to the upside.
- SELL / PUT arrow: the Parabolic SAR dots flip above price while the Rate of Change is below zero — momentum and trend agree to the downside.
- Non-repaint: signals confirm on the closed candle, so an arrow stays put once it prints — what you see in history is what you would have traded live.
Built-In Alerts
The moment a valid signal appears, ROC + SAR Alert can notify you four different ways — each one can be switched on or off in the settings:
- 📢 Popup alert inside MetaTrader
- 🔊 Sound alert so you hear every signal
- 📱 Mobile push to the MetaTrader app on your phone
- ✉️ Email alert straight to your inbox
Adjustable Settings
Tune the indicator to your own style — Parabolic SAR step and maximum, Rate of Change period and applied price, a minimum ROC strength filter to skip weak signals, plus arrow colors, size, and each alert toggle.
How to Use ROC + SAR Alert
Drag ROC + SAR Alert from the Navigator panel onto your chart. The Parabolic SAR flip marks the trend change, and the ROC filter makes sure momentum actually backs it. M5–M30 for short-expiry trading, H1 for intraday forex.
Key Settings
| Setting | Default | What it does |
|---|---|---|
| SAR Step / Maximum | 0.02 / 0.2 | Standard Parabolic SAR speed — a smaller step flips less often |
| ROC Period | 10 | How far back momentum is measured |
| Min |ROC| Strength | 0 (off) | Raise above 0 to skip flips that happen on weak momentum |
Trading the Arrows
- Aqua arrow (BUY / CALL): the SAR just flipped below price with positive momentum — enter on the next candle open.
- Red arrow (SELL / PUT): the SAR flipped above price with negative momentum.
- Signals confirm on the closed candle — arrows never repaint or move.
- Tip: the SAR dots after the flip make a natural trailing stop — trail your exit along them until they flip again.
