📊 Simmer Calibration Report

You think you know where your edge comes from. This skill tells you if you're right.

> This is a template. Point it at any Simmer JSONL trade journal — live, sim, or exported from anywhere — and get a full calibration breakdown. No strategy-specific logic baked in. Your journal, your numbers.

Setup

1. Install dependencies:

```bash

pip install simmer-sdk

```

1. Set your API key:

```bash

export SIMMER_API_KEY=your_key_here

```

1. Run it:

```bash

python calibration_report.py --live

```

That's it. If your journal exists at the default path, it just works.

Configuration

Set config inline:

python calibration_report.py --set lookback_days=60
python calibration_report.py --set min_trades=5

Quick Commands

# Sim journal (dry run data)
python calibration_report.py

# Live journal
python calibration_report.py --live

# Custom journal path
CALIB_JOURNAL_PATH=/path/to/journal.jsonl python calibration_report.py

# Show config
python calibration_report.py --config

# Summary only (good for cron)
python calibration_report.py --live --quiet
