Use when computing net P&L for a leveraged or short book: tiered blended margin-loan rates, short borrow fees on collateral value, 360 versus 365 day counts, and calendar-day accrual across weekends and holidays.
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 when computing net P&L for a strategy that borrows — one that runs leverage, carries positions overnight, or sells short. Backtests that ignore financing overstate returns and Sharpe by the entire cost of the leverage that produced them, and the overstatement scales with the benchmark rate: a book carrying a permanent debit at a 5% margin rate gives up 5% a year before it makes a single trading decision. Use it to answer three questions with numbers rather than estimates: what does the debit balance cost under the broker's **tiered** schedule, what does the borrow cost on the short book, and what does gross P&L become once both are subtracted. ## When NOT to Use - **As a substitute for the broker's own interest statement.** This computes an accrual from balances you supply. Reconcile it against the monthly posting before trusting it; a systematic gap usually means the collateral basis or the day-count is wrong. - **To model multi-year compounding.** Brokers accrue daily and post monthly (IBKR on the third business day of the following month), so interest starts earning interest …

How to install
mdr add himanshuj16/algo-trading-skills/broker-margin-interest-accrual-tracking@sha256:ffa6f64f088d0f22The line at the top of this page pins the label v3.0.0, 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.
