Vest platform: a client for Vest Markets, traded on a session the extension relays
Vest (next.vestmarkets.com) is a perps prop firm: index, metal and energy
perps on CME hours, plus stocks, FX and crypto. It joins as a fourth
platform, 'vest', on the DXtrade engine paths. Those are now keyed by
isNotionalPlatform() instead of === 'dxtrade': the firm's own symbols,
percent fees, notional sizing from volatility, and a scheduler lane of its
own.
- Login is relayed, not stored. Vest signs people in with Google through
Privy and renews the session with a device key the browser won't export.
Extension 0.17.0's vest-relay.js reads the token the Vest app renews for
itself (~15 min). It renews nothing, so the tab is never logged out. The
background script posts that token to POST /api/vest/session, which holds
it in memory only. With no Vest tab open on a machine that trades Vest,
the extension opens one.
- The firm's credential is the Vest login's wallet address. The dashboard's
form offers the relayed wallet with one click.
- VestClient (lib/vest-class.ts), mapped from the web app's traffic and code
since Vest publishes no API:
- Reads the capital accounts, balances (free amount plus position
collateral), positions and open orders with the user token.
- Mints per-account tokens for orders and transactions.
- Names accounts for their rules (V50K-E-D3-T10-34, V50K-F-D3-34,
V25K-I-7) so account-type prefixes can match.
- Takes Vest's own max-drawdown and daily-loss floors. dayStartBalance =
floor + the type's limit, so the engine's room is never more than
Vest's.
- Uses each symbol's taker fee and margin rate from exchangeInfo, and
hourly volatility over in-session hours only.
- Places take-profit and stop as position legs, which Vest cancels as an
OCO pair.
- Daily P&L and fund rows come from /v3/transactions by Vest's 20:00 ET
day. A books check holds an account, naming the transaction types, when
the balance and the transactions disagree.
- scripts/check-vest.mjs (in npm run check): Vest's day across DST, account
names, parsing, volatility gaps, market hours, the session store.
Not yet run against Vest with a live session: the order and exit bodies
come from the app's code, and the transaction classification from its enum.
