NewTrade review for Schwab options and SPX 0DTE traders
QuantOS rebuilds every Schwab trade, replays it against the market you saw, and shows which habits are quietly costing you. Stop guessing why a day went wrong. Keep doing what works, and drop what doesn’t.

Each rule is costed from your own round trips. A rule with too few qualifying trades shows as PARTIAL instead of a score.
What You’ll Discover
Connect your account and QuantOS works through your history. Most traders learn something about themselves in the first week.
Oversizing, trading late, cutting winners early. Each habit gets a dollar cost from your own trades, so you know which one to fix first.
P/L broken down by time of day and hold time. Find the window where your setups actually work, and the one where they don’t.
Replay shows how far price ran after your exit. See how much of each move the market offered and how much you took home.
Illustrations show example data.

Built for Schwab
QuantOS reads Schwab statements, transactions, quotes and option chains through the official API. Accounts that moved from TD Ameritrade work too.
Features
A journal tells you what happened. QuantOS also shows you the market around each trade and which of your habits cost the most.
Accounts and P/L
QuantOS merges brokerage statements, stored API sessions and live activity into one record of round trips. Where sources disagree, the statement wins.

Example rows. Dates are shown as DD-MON-YYYY throughout the app.
Trade Replay
Each round trip plays back bar by bar with volume and your real entry and exit markers. The replay keeps running past your exit, so you can see how far the move went (MFE) and how deep it pulled back (MAE).
| Setup | Offered | Taken | Captured |
|---|---|---|---|
| Opening drive | 10:02 | 10:04 | 0% |
| VWAP reclaim | 11:18 | — | Skipped |
| Gamma flip test | 13:41 | 13:42 | 64% |
What was offered against what was taken. Example session.
Behaviour and Discipline
Behaviour scoring works from evidence. Each rule needs a minimum number of matching trades before it gets a score. If the evidence is not there yet, QuantOS shows the rule as PARTIAL instead of guessing.
Rules and violation costs. Example figures.
SPX 0DTE Workspace
The SPX workspace combines dealer gamma (GEX), the gamma flip, expected move and VWAP into explicit gates. Each gate returns CALL, PUT, WAIT or NO TRADE, and each one shows the input that decided it.
Example gate readout.
Market Preparation
The major indexes, VIX, all ten sector ETFs, bonds, the dollar, gold and oil on one board. Scheduled BLS, Fed and Treasury releases are listed with official headlines. Every figure links back to where it came from.
Example premarket board.
Evidence Standards
Trading tools often present guesses as signals. QuantOS labels each result with how it was produced, so you can tell how much weight it deserves.
UNCALIBRATEDA heuristic score that has not yet been fitted to real outcomes. It ranks setups but is not a probability.
ESTIMATEDA value inferred from partial inputs, such as dealer positioning taken from open interest.
Derived, Not ObservedCalculated from other data, not reported by the broker or exchange.
PARTIALNot enough matching trades to score the rule. QuantOS shows how much evidence it still needs.
REFUTEDA signal that failed its control test. It stays visible as context but has no vote in any decision.
Price Confirmation RequiredNews interpretation from a language model is shown as context. It never counts as an entry signal on its own.
You sign in on Schwab’s own page. QuantOS never sees or stores your brokerage username or password.
QuantOS reads your accounts, transactions and market data. Trade review never places an order.
Your trade record is stored in a database you control, with an encrypted session that refreshes itself.
