pine-script

## Overview

This skill exports a Vibe-Trading strategy to **all major trading platforms** in one go.
Output file: `artifacts/strategy.pine` (inside the run directory).

Supported platforms (always generate ALL):

| Group | Platforms | Language |
|-------|-----------|----------|
| International Charts | TradingView | Pine Script v6 |
| China Equities | 通达信 / 同花顺 / 东方财富 | TDX Formula |
| Forex / CFD | MetaTrader 5 | MQL5 |

## Workflow: Export from Backtest

1. `load_skill("pine-script")` — read this guide
2. `read_file("config.json")` — understand instruments, dates, parameters
3. `read_file("code/signal_engine.py")` — understand the Python strategy logic
4. **Translate** the strategy to ALL platforms using the references below
5. `write_file("artifacts/strategy.pine")` — save the combined output
6. Return the code in a code block with usage instructions per platform

## Workflow: Generate from Description

1. `load_skill("pine-script")` — read this guide
2. Write indicator/strategy code for ALL platforms based on the user's description
3. `write_file("artifacts/strategy.pine")` — save the combined output
4. Return the code with usage instructions

## Output Format

The output file uses this structure (all platforms in one file):

```

### Python → Pine Script Mapping

| Python (pandas/numpy) | Pine Script v6 |
|------------------------|----------------|
| `df['close'].rolling(n).mean()` | `ta.sma(close, n)` |
| `df['close'].ewm(span=n).mean()` | `ta.ema(close, n)` |
| `ta.RSI(df['close'], n)` or manual RSI | `ta.rsi(close, n)` |
| `ta.MACD(df['close'])` | `[macdLine, signalLine, hist] = ta.macd(close, 12, 26, 9)` |
| `df['close'].rolling(n).std()` | `ta.stdev(close, n)` |
| `df['high'].rolling(n).max()` | `ta.highest(high, n)` |
| `df['low'].rolling(n).min()` | `ta.lowest(low, n)` |
| `df['close'].pct_change()` | `(close - close[1]) / close[1]` |
| `df['volume'].rolling(n).mean()` | `ta.sma(volume, n)` |
| `df['close'] > df['close'].shift(1)` | `close > close[1]` |
| Bollinger Bands | `[mid, upper, lower] = ta.bb(close, length, mult)` |
| ATR | `ta.atr(length)` |
| ADX | `ta.adx(high, low, close, length)` |
| Stochastic | `ta.stoch(close, high, low, length, smoothK, smoothD)` |
| CCI | `ta.cci(close, length)` |
| Williams %R | `ta.wpr(length)` |
| MFI | `ta.mfi(close, length)` |
| OBV | `ta.obv` |
| VWAP | `ta.vwap` |

| `(fast < slow) & (fast.shift(1) >= slow.shift(1))` | `ta.crossunder(fast, slow)` |
| `signal.where(condition, 0)` | `condition ? value : 0` |
| `np.where(cond, val_true, val_false)` | `cond ? val_true : val_false` |
| `signal.clip(-1, 1)` | `math.
