Hold the whole session in your hands.
A real-time behavior monitor for Topstep futures traders — live limits, live alerts, and every account under one login, running 24/7 on your own PC.

Every fill, watched live.
Watch every trade as it happens. The Live Feed streams your fills, balance changes, and risk exposure in real time, the moment they occur, and flags risky behavior before it costs you your account. Get desktop alerts even when you're not staring at the screen, so nothing slips by while you're heads-down in a trade.
Numbers with a memory.
See exactly where you stand. Win rate, profit factor, an equity curve, and your account balance over time, distilled into one clear view. No spin, no interpretation, just the numbers that tell you what's actually working and what isn't.
Every account, true limits.
Every account you trade, side by side. Whether it's one Combine or a stack of them, see real-time risk on your active account and a reliable read on every other, with any account approaching a breach flagged in red before it's too late.
Closed, never lost.
Closed or converted accounts don't just vanish. Every trade, every stat, every lesson stays on record and reviewable, so your history keeps working for you long after an account's status changes.
Your trades, on the record.
Every trade, mapped to the day it happened. A full calendar view with P&L, auto-flagged behavioral patterns, and a candle-by-candle replay of the exact price action around each trade, so you can see not just what you did, but why it worked or didn't.
And so much more.
