SuperTrend Strategy with Trend-Based Exits

**SuperTrend Strategy with Trend-Based Exits & Qty Rounding**

**Overview**
This automated strategy uses the SuperTrend indicator to detect trend reversals and manage both entries and exits. Position size is calculated dynamically based on a fixed risk-per-trade in USD and the ATR-based stop-loss distance, then rounded down to a configurable lot step to guarantee valid order sizes on any exchange.

**Key Features**

* **Dynamic Position Sizing**

```
raw_qty = risk_per_trade / |close – SuperTrend|
qty = floor(raw_qty / lot_step) * lot_step
```
* **Trend-Based Entries & Exits**

* On SuperTrend flip: close existing position, then open new in the opposite direction.
* Uses one strategy.close() + one strategy.entry() per reversal—no duplicate signals.
* **Trailing Stop**

* A built-in stop follows the SuperTrend line, locking in profits.
* **Qty Rounding**

* Ensures orders are always integer (or custom-step) sizes:
– Default `lot_step = 1` for whole contracts
– Use `lot_step = 100` for coins like PEPE
– Use `lot_step = 0.01` for ETH/BTC

**Inputs**

| Input | Description | Default |
| -------------------- | -------------------------------------------------------- | :-----: |
| Risk per trade (USD) | Maximum dollar risk per trade | 150 |
| ATR Length | Period for ATR used in SuperTrend | 50 |
| SuperTrend Factor | Multiplier applied to ATR for the SuperTrend calculation | 3.5 |
| Qty step | Minimum tradeable lot size (integer or decimal) | 1.0 |

**Usage & Setup**

1. **Manual Sync (one-time)**

* Check the rounded `qty` and trend direction on your chart.
* Open a matching market order on your exchange to align your real position with the strategy’s virtual position.
2. **Create TradingView Alert**

* Condition: **“Order fills”**
* Message: use your exchange’s required JSON template (e.g. Bybit’s).
* Webhook URL: point to your execution endpoint.
3. **First Reversal**

* The initial `close` signal will sync without sending a webhook.
* Subsequent `close` + `entry` signals will each fire exactly one valid webhook.
4. **Live Trading**

* Strategy will continuously close and reverse positions based on SuperTrend flips, with a SuperTrend-based trailing stop.

**Tips**

* Adjust **ATR Length** & **Factor** per asset volatility:

* Low vol: ATR 30–50, Factor 3.0–4.0
* Mid vol: ATR 50–75, Factor 4.0–4.5
* High vol: ATR 75–120, Factor 4.5–5.0
* If you trade a new coin, screen it quickly with 3–4 proven parameter sets, then refine around the best performer (3×3 grid search).
