Renders a JPG chart of a ticker's daily candles with EMA 9/20 lines, their golden/death crossovers marked, and an RSI 14 panel with 70/30 bands. Use when the user asks for a chart, candle plot, EMA crossover chart or RSI chart of a stock.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Chart: EMA crossover and RSI Daily candles from Yahoo with EMA(fast) and EMA(slow) over the price, a green ▲ under the candle of each golden cross (fast crosses above slow) and a red ▼ over each death cross, and RSI in a lower panel with 70/30 lines. Extra history is downloaded before the window, so the lines are settled from the first plotted bar. ## Instructions ```bash uv run python scripts/chart.py SYMBOL [--period 6mo] [--fast 9] [--slow 20] [--rsi 14] [--output PATH] ``` Show the user the image after it's written. ## Arguments - `SYMBOL` - Ticker - `--period` - Plotted window: `1mo`, `3mo`, `6mo` (default), `1y`, `2y` - `--fast` / `--slow` - EMA lengths (default 9 / 20); fast must be shorter - `--rsi` - RSI length (default 14) - `--output` - JPG path (default `sandbox/<SYMBOL>_ema_rsi_YYYY-MM-DD_HHmm.jpg`) ## Output JSON: `symbol`, `path`, `period`, `last_date`, `close`, `ema_fast_length`, `ema_slow_length`, `ema_fast`, `ema_slow`, `trend` (`bullish` when fast is above slow), `rsi`, `crossovers` (`date`, `type` golden/death, `ema_fast` at the cross) inside the window, `generated_at`, `data_delay`; or `error`. …

How to install
mdr add staskh/trading_skills/chart-ema-rsi@sha256:f5b092544cbc6dc4The line at the top of this page pins the label git:20261108.c50df7a, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
