About Trader Brain

Most trading content asks you to trust a person. This tool asks you to check one.

Trader Brain takes a trader's public, documented way of reading the market, turns it into an explicit engine, and lets anyone replay that engine on real historical data. The point is not to predict. The point is to make a trading style inspectable: which rules fire, which past trades were similar, where the stop would be, and how often that logic was right.

How a profile is built

See the traders for the profiles that exist and how to request one.

1. Public videos are transcribed and split into evening plans, live trades and teaching sessions.
2. Each is extracted into a structured record: the market context, the thesis in the trader's own framing and in conventional terms, entries, stop logic, management and the claimed outcome.
3. Rules the trader states explicitly are written down, and every studied trade is counted as supporting or contradicting each rule. Confidence comes from those counts.
4. Stated levels and claimed outcomes are checked against real one-minute market data, and the trader's hit rate is measured with pre-registered tests.
5. A persona (voice, first principles, honesty constraints) becomes the model's system prompt; the rulebook and the past trades become its grounding.

What keeps it honest

• The market state is deterministic and leakage-free: only bars up to the chosen time are used.
• Confidence is never the model's opinion of itself. It is the trader's own historical hit rate for that kind of open, shrunk toward 50% and capped.
• Hard rules are enforced after the model answers. A runaway gap-up can never produce a long read.
• Reads after the morning are labeled extrapolated and scored separately, because the trader has no recorded opinion on afternoons.
• Every read is logged with its full state and scored against the bars that followed, by the same rule for every read.

What it is not

Not investment advice, not a recommendation, and not a signal service. The sizing panel illustrates what a read implies for a chosen amount of risk, with lot size and option behaviour shown as editable assumptions; verify them with your broker before relying on them. Index options are leveraged instruments and most retail participants lose money. If you trade, that decision and its consequences are yours.

The traders whose public videos were studied have not endorsed this tool. Profiles are research profiles built from publicly available material; a profile is taken down on request.
