Create an interactive Plotly chart for a technical indicator on a symbol.
Arguments
Parse $ARGUMENTS as: indicator symbol exchange interval
$0 = indicator name (e.g., ema, rsi, macd, supertrend, bbands, adx, stochastic, ichimoku, obv, vwap). Default: ema$1 = symbol (e.g., SBIN, RELIANCE, NIFTY, AAPL). Default: SBIN$2 = exchange (e.g., NSE, BSE, NFO, NSE_INDEX). Default: NSE. For US symbols use: YFINANCE$3 = interval (e.g., D, 1h, 5m). Default: D
If no arguments, ask the user which indicator and symbol they want.
Instructions
- Read the indicator-expert skill rules for reference patterns
- Create
charts/{indicator_name}/ directory if it doesn't exist (on-demand)
- Create a
.py file in charts/{indicator_name}/ named {symbol}_{indicator}_chart.py
- Use the matching template from
rules/assets/{indicator}_chart/chart.py as starting point (if available)
- The script must:
- Load
.env from project root using find_dotenv()
- Fetch data via OpenAlgo
client.history() (or yfinance for US symbols)
- Normalize data: convert index to datetime, sort, strip timezone
- Compute the indicator using
openalgo.ta
- Create a Plotly chart with
template="plotly_dark" and xaxis_type="category"
- Overlay indicators (EMA, Bollinger, Supertrend, Ichimoku) go on the candlestick panel
- Subplot indicators (RSI, MACD, Stochastic, ADX, Volume, OBV) go below in separate panels
- Use
make_subplots for multi-panel layouts
- Add horizontal reference lines where appropriate (RSI 30/70, Stochastic 20/80)
- Print a plain-language explanation of the current indicator reading
- Save chart as HTML:
{symbol}_{indicator}_chart.html
- Show chart with
fig.show()
- Never use icons/emojis in code or output

Multi-Indicator Charts
If user asks for "multi" or multiple indicators, create a comprehensive multi-panel chart with:
- Row 1: Candlestick + EMA overlays
- Row 2: RSI(14)
- Row 3: MACD(12,26,9)
- Row 4: Volume bars
Signal Markers
If the indicator generates clear buy/sell signals (e.g., crossover, supertrend direction change), add triangle markers:
- Buy: green triangle-up markers
- Sell: red triangle-down markers
