Clearstreet borrow check

Skill clear-street/clearstreet-skills/skills/clearstreet-borrow-check

Check the borrow / short-sale / margin status of a US stock or ETF — easy-to-borrow flag, threshold-security and short-prohibited flags, long and short margin rates, PTP (publicly-traded partnership) flag, liquidation-only status, and average daily volume — and explain each flag in plain English. Use when the user asks "is X hard to borrow", "can I short X", "what's the margin rate on X", "is X on the threshold list", or "is X a PTP".From its SKILL.md

Borrow Check

Translate the borrow, margin, and short-sale flags on a US instrument into a plain-English verdict. Useful for short-sellers, options structurers, and margin traders.

Prerequisites

Python 3.9+ (standard library only)
CLEARSTREET_API_KEY set in the environment — see the repo README

Quick start

python3 scripts/borrow.py NVDA
python3 scripts/borrow.py GME AAPL TSLA   # multiple tickers

Usage

borrow.py SYMBOL [SYMBOL ...] [--json]

Examples

Ask	Command
"Is GME hard to borrow?"	`borrow.py GME`
"Can I short TSLA?"	`borrow.py TSLA`
"What's the margin rate on NVDA?"	`borrow.py NVDA`
"Is BX a PTP?"	`borrow.py BX`
"Borrow status for NVDA, AMD, AVGO"	`borrow.py NVDA AMD AVGO`

Output

Per symbol: a one-line verdict, a flag table, and plain-English notes on each non-default flag.

Workflow

Run python3 scripts/borrow.py <SYMBOL>....
Present the output as-is — it's already explanatory. Don't add an instrument-identity table with option-only fields (expiry / strike) or the internal instrument id.
For company context, chain to clearstreet-fundamentals-deep-dive or clearstreet-omni-research.

See reference.md for the full field list and what each flag means.

Safety

Read-only. Does not place trades or recommend positions — it reports the operational and regulatory state of an instrument. Flags can change intraday. Output is informational, not investment advice.
