Prisme · Bitcoin chart research

Examine what you think you see on a Bitcoin chart.

A level, a zone, a double bottom: instead of eyeballing them, Prisme measures them, dates them and also shows the cases that failed. The same chart and the same measurements serve humans and their AIs, connected over MCP.

Measured, never a signal

Horizontal levels, price zones, double tops and double bottoms. Prisme counts contacts, confirmed rejections and crossings, keeps incomplete cases apart, and dates the moment a pattern becomes detectable.

Invalidated and expired patterns stay visible. These are descriptive measurements, never a buy or sell signal.

Prisme workshop: a double bottom on BTC/USD 15 min, its two points, its neckline and the date it became detectable — Real capture: double bottom, neckline and “detectable here”.

A replay that never sees what comes next

Pick a past date: Prisme cuts the history before computing anything. Candles, indicators and patterns are recomputed as if the future did not exist, across four linked views.

Step by step or automatic playback. Your AI reads the same cut, through the same Rust engine.

The blind Arena

A randomly drawn BTC window, price rebased to 100 and relative dates, so the period is harder to recognise. You call rise or no rise with a confidence level.

The forecast is sealed before the reveal, then scored with the Brier score against the 50% reference. Every round stays in the log, abandoned ones included. Humans and AIs play the same round.

Prisme blind Arena after the reveal: the T0 line, the move at the chosen horizon and the Brier score — Test round: Brier 0.490 against 0.250 for the 50% reference. Lower is better; one round proves nothing.

The bridge to the Lab

A saved observation (level, zone, filter, double top or bottom) becomes a hypothesis sheet: exact market, declared period already seen, candle fingerprints. The Strategy Arena Lab is the one that judges it.

Prisme also reads a Lab result back on its BTC history: declared verdict, log of moves, checked candles. Today the exchange goes through a file, by hand.

Prisme Lab result reader: the declared test period on the chart and the log of moves — Lab result reader, on a synthetic example (no real result).

Your AI reads the same chart

Prisme exposes its workshop to AI clients over MCP: 38 workshop tools and 7 separate Arena tools in edition 20. An AI can propose a level or an annotation; you keep or remove it. No AI model is embedded and no tool places an order.

Prisme does not replace TradingView, it complements it. You keep your usual chart; Prisme is for checking an idea before believing it, and the Lab gives the verdict.

Prisme explores. The Lab designs and judges. You decide.
Built in Rust: the browser (WebAssembly, WebGPU) and the MCP server share the same calculations. 158 Rust tests at edition 20.
Data: Coinbase BTC/USD spot, public feed.
