Prisme: examine what you think you see on a Bitcoin chart

On a chart, you see things. A support that "holds", a double bottom "forming", a zone where price "always bounces". The problem is not seeing them: it is knowing whether you measured them, or only believed them.

Prisme is the workshop we are building for that exact question, on a single market: Bitcoin. Discover Prisme.

Research on past data, not investment advice.

What Prisme does today

It measures instead of signalling. A horizontal level, a price zone, a double top or a double bottom become measured objects: contacts, confirmed rejections and crossings, incomplete cases kept apart, the date from which a pattern is detectable. Invalidated and expired patterns stay on screen. None of this is a buy or sell signal.

It replays the past without the future. In replay, Prisme cuts the history at the chosen date before computing anything. Candles, indicators and patterns are recomputed as if the future did not exist, across four linked views. That is the minimum condition to judge a reading: not knowing what comes next.

It tests your reading blind. In the Arena, a BTC window is drawn at random, the price rebased to 100 and the dates made relative. You call rise or no rise, with a confidence level. The forecast is sealed before the reveal, then scored with the Brier score and compared with the 50% reference. Every round stays in the log, abandoned ones included. A single round proves nothing: the series is what counts.

It prepares the hand-off to the judge. A saved observation becomes a hypothesis sheet (exact market, declared period already seen, candle fingerprints) meant for the Strategy Arena Lab. The other way round, Prisme reads a Lab result back on its BTC history: declared verdict, log of moves, checked candles. Today this exchange goes through a file, by hand.

The same chart for you and your AI

Prisme opens its workshop to AI clients over MCP: 38 workshop tools and 7 separate Arena tools in edition 20. An AI reads the same candles, the same measurements and the same replay cut as you, through the same Rust engine. It can propose a level or an annotation; you keep it or remove it. No tool places an order.

The judge stays the Lab

Prisme explores. The Lab designs and judges. You decide. An observation, even cleanly measured, remains a hypothesis: only the Lab, with a sealed period and an attempt counter, can say whether a rule holds or is a mirage. That is why every Prisme screen carries the same line: exploration, not a verdict.

Prisme does not replace TradingView: it complements it. You keep your usual chart; Prisme is for checking what you think you see on it.

Where Prisme stands

Prisme runs locally today. The public Arena is coming to strategyarena.io. It covers BTC only, from the public Coinbase BTC/USD spot feed.

Meanwhile, the Lab is free: download the Strategy Arena Lab, or plug your AI into the Lab. The Prisme page shows the presentation video and real captures of each feature.
