TopstepX and Tradovate report fills, so a trade is built from them, flat
to flat (lib/fill-trades.ts), off the window each sync already reads:
TopstepX's two days of Trade/search, Tradovate's sync snapshot. Neither
says who placed an order, so every order the bot places is noted in
own_orders, and a trade is the bot's when its opening fill's order is
one; its stop or take-profit closing it reads as such. A contract is
written only when the position before its window comes out the same
two passes running, so a fill landing between the position and history
reads can't build the wrong trades.
DXtrade reports positions: its record groups the last two days' filled
orders by position code, with each close's SETTLEMENT and COMMISSION.
The bot's own orders carry af- codes, so nothing is kept locally. Only
accounts with something going on are read, at most every 5 minutes.
The Trades button shows on every firm with a login, and the account
page lists any account's trades.

The firm rolls its day at 22:00 UTC; our trade date at 5 PM CT. In summer
they coincide, in winter the firm's rolls an hour earlier. New entries are
already kept out of that hour, but a take-profit or stop that fills in it
was booked to the day before. firmDayOf labels the firm's day the way
currentTradeDateCT labels ours, and the sync's transfer window now starts
at the firm day behind today's trade date.

- Transfers: a close books its SETTLEMENT and COMMISSION under one
transaction code, and keying by the code alone let the commission
overwrite the P&L. Keys now carry the type, so the day-start balance,
daily-loss room, realized P&L, daily history and books check all see
closed-trade profit and loss.
- Volatility from a week of hourly closes (was 48 h), still measured once
per trade date, so one quiet weekend can't triple a hold estimate.
- Each symbol's margin rate from the account's instrument details caps
the position at available funds / rate (Tradeify: 5:1 crypto, 2:1
stocks); the account type's max notional stays as an optional ceiling.
- Firms with overnight financing add the swap a winning leg is expected
to pay (the winners' mean hold, (A²+2AB)/3σ²) to its take-profit, and
the sizing and hold estimate count it.

The symbol map's fixed notional per contract is gone: every DXtrade leg is
sized from the instrument's recent volatility for the firm's target hold
(blank = 12 h), and a candidate without a volatility isn't picked. Percent
commission and every-day trading are ignored on non-DXtrade firms, which keep
measured per-contract fees and the CME calendar.

- DXtrade client (lib/dxtrade-class.ts): REST session login with lockout-safe
backoff, 60s sync of accounts/metrics/positions/orders/transfers, history and
fund transactions from cash transactions, day-start balance at the 22:00 UTC
reset, CLOSE-by-positionCode exits (native OCO group, else a stop-first
emulated pair), a cross-account hedge guard, stray-order reaper.
- Instrument selector: the firm's symbol map lists candidate symbols per CME
root; the cheapest tradable one per unit of recent hourly volatility wins
(spread + 2x commission [+ financing] / sigma).
- Fees: a firm's commission % of notional prices every fee off the fill; the
take-profit is solved in closed form so the leg nets its target.
- Hard daily loss limit per account type: every leg carries a stop keeping the
firm's day inside the limit less a 10% reserve and both fees (rounded in);
a green day never widens it; no room or a refused bracket flattens.
- Notional sizing where the platform prices positions: target-hold volatility
sizing or the symbol map's fixed notional, under a per-type notional cap.
- Every-day firms trade weekends/holidays; the scheduler runs lanes (futures,
one per DXtrade firm) with their own hours, flat gate, mutex and batches.
- The catalog sync skips platforms this build doesn't know instead of treating
them as Tradovate. One shared fireLeg replaces the duplicated batch/copy code.
- npm run check: fee/stop/sizing/hours/selector checks; scripts/dxtrade-smoke.mjs
confirms the API against a real login before trading.
