Check whether a backtest's passive (maker/limit) fills survive a queue — re-run the order log against top-of-book and trades and compare the backtest's fill rate with a queue-proxy fill rate. For quant researchers with resting limit orders in their backtest. Trigger with "check my fills", "are my maker fills realistic?", "fill gap", "fill at touch", "queue position check", "would these limit orders have filled?".
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
# Fill gap — do your backtest's passive fills survive a queue? Runs `bt2live fill-gap` from the `backtest2live` package and interprets the result. The simulation is deterministic and lives in the CLI; your job is to get the inputs right and explain what the numbers mean for the user's strategy. ## Step 1 — Get the order log into shape One CSV row per order. Required: time (`ts`, epoch or ISO, UTC), `side` (buy/sell), `price`, `size` (base units). Strongly recommended: the backtest's own fill flag (`filled` true/false), the order's end or cancel time (`end_ts`), and per-order `pnl`. If the user's engine exports a different shape, write a short conversion script and show it to them. Don't guess the meaning of a column you can't identify; ask. ## Step 2 — Pick the market data - Orders on Binance USDT-M futures up to 2024-03-30: `--venue binance-um --pair <SYMBOL>`. Orders on Bybit perpetuals, 2023 to yesterday: `--venue bybit-linear --pair <SYMBOL>` (or `bybit-inverse`). Both download 100–250 MB per day and cache it; say so before running. …

How to install
mdr add martianmobile/backtest2live/fill-gap@sha256:397f8241fca991efThe line at the top of this page pins the label git:20261015.7fe3b8d, 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.
