Indicator Expert

This is your go-to for anything involving technical indicators in OpenAlgo, especially if you're working with Indian markets. It automatically routes to openalgo.ta's 100+ Numba-optimized indicators instead of letting you reinvent SMA for the hundredth time. Handles the full workflow: fetching OHLCV data via OpenAlgo or yfinance, normalizing timestamps, plotting with Plotly dark theme, building real-time WebSocket feeds, and generating properly cleaned signals with exrem. The skill enforces sensible defaults like never hardcoding API keys, always using njit for custom indicators, and explaining chart outputs in plain language. If you're building scanners, dashboards, or multi-timeframe analysis with Indian equities, this keeps you from fighting with data normalization and signal noise.

OpenAlgo Indicator Expert Skill

Environment

Python 3.12+ (required by openalgo 2.x) with openalgo, pandas, numpy, plotly, dash, streamlit
Data sources: OpenAlgo (Indian markets via client.history(), client.quotes(), client.depth()), yfinance (US/Global)
Real-time: OpenAlgo WebSocket (client.connect(), subscribe_ltp, subscribe_quote, subscribe_depth)
Indicators: openalgo.ta (ALWAYS — 100+ indicators computed by a compiled Rust core, full speed from the first call)
Charts: Plotly with template="plotly_dark"
Dashboards: Plotly Dash with dash-bootstrap-components (default) OR Streamlit with st.plotly_chart() — use Streamlit only when the user explicitly asks for it
Custom indicators: vectorized NumPy composed from openalgo.ta primitives (Rust core — no JIT, no warmup)
API keys loaded from single root .env via python-dotenv + find_dotenv() — never hardcode keys
Scripts go in appropriate directories (charts/, dashboards/, custom_indicators/, scanners/) created on-demand
Never use icons/emojis in code or logger output
