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.

TopstepX's gateway reports a fill's exchange and NFA fees only (NQ $1.39 a
side, GC $1.66, CL $1.51, MNQ $0.36). Topstep's own commission, $0.50 a side
on a full-size contract and $0.25 on a micro, comes off the balance with no
trade row carrying it, so our P&L ran $1.00 per full-size round turn above
Topstep's. On 2026-10-18 the combines sat $6 to $8 under their books and an
XFA $27.50 under, and one combine had its $18 booked as a "withdrawal".
Topstep's published round turns (NQ $3.78, MNQ $1.22, GC $4.32, CL $4.02)
are the reported fees plus this commission.
- lib/topstep-fees.ts: the per-product commission table, and TopstepX
contract ids mapped to roots (ENQ, GCE and CLE as seen on real fills,
overridden by contracts the client resolves itself; an unknown product
pays the full-size rate and is logged once).
- Daily P&L, today's realized, and so the measured entry fee a take-profit
is placed from, all net the commission. The 90-day refetch rewrites the
cached days.
- npm run check: the table against the micro flags, the id mapping, and
the published round turns.
