Use before promoting a paper-tested strategy to live capital, to measure how far demo fill latency, slippage, queue depth and partial-fill rates diverge from matched live executions, and derive a Sharpe haircut from the gap.
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
## When to Use Invoke this skill prior to deploying a paper-tested trading strategy into live capital. Broker paper/demo accounts systematically inflate performance metrics by granting instant fills, ignoring limit order queue depth, suppressing market impact, and under-reporting slippage. This skill records matched execution logs from demo and live trades to quantify the execution realism gap and apply Sharpe ratio haircut factors. ## When NOT to Use - **As the only gate on a live promotion decision.** $R$ measures execution fidelity alone. It says nothing about selection bias or backtest overfitting — for that, use the Deflated Sharpe Ratio (Bailey & López de Prado, 2014), which corrects a different and equally fatal source of inflation. The two are complementary, not substitutes. - **With few matched executions.** A score computed from a handful of fills is indicative only; the assessor flags `is_sample_sufficient=False` below `min_samples` and you should not size capital on a flagged result. …

How to install
mdr add himanshuj16/algo-trading-skills/demo-account-realism-gap-assessment@sha256:e0c15633566ea994The line at the top of this page pins the label v1.0.0, 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.
