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 Indicator Chart Types Overlay Indicators (on candlestick panel) Indicator Chart Type ema, sma, wma, dema, tema, hma Line overlay bbands Fill-between bands + midline supertrend Color-coded line (green=up, red=down) ichimoku 5 lines + cloud fill keltner, donchian Fill-between channels sar Dot markers above/below price ma-envelopes Upper/lower band lines Subplot Indicators (separate panel below) Indicator Chart Type rsi Line + horizontal 30/70 zones macd Line + signal + histogram bars stochastic K% + D% lines + 20/80 zones adx DI+, DI-, ADX lines + 25 threshold cci Line + horizontal +100/-100 zones williams_r Line + -20/-80 zones obv Line (cumulative) mfi Line + 20/80 zones volume Bar chart (green/red by price direction) atr Line (volatility) 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 Data Periods Interval Default Lookback D 1 year (365 days) 1h 6 months (180 days) 15m, 30m 3 months (90 days) 5m 1 month (30 days) 1m 7 days Plain-Language Explanation After creating the chart, print a brief explanation: SBIN — RSI(14) Analysis Current RSI: 42.3 Interpretation: Neutral zone (between 30-70).
