About
Built by a trader who audited their own losses
QuantOS started as a personal tool for reviewing SPX 0DTE trades. It grew into a full workspace because the usual trading journals couldn’t answer the questions that mattered.
The Problem
A trading journal records what you did. It rarely shows what the market offered at the moment you acted, or whether the loss came from the idea or from how you carried it out.
A full audit of a year of round trips found that the setups were mostly sound. The losses came from three habits: trading too large, trading too late in the day, and closing positions within two minutes. None of those showed up clearly in a P/L chart.
The Approach
QuantOS rebuilds each trade from the broker’s own records, replays it on the chart it happened on, and costs each habit separately.
It also refuses to overstate. A score that hasn’t been tested says UNCALIBRATED. A rule without enough trades says PARTIAL. A signal that failed its test says REFUTED and loses its vote. The methodology explains each rule.
