Prisme · Bitcoin chart research

Prisme, a free online Bitcoin chart workshop: examine what you think you see.

A level, a zone, a double bottom: instead of eyeballing them, Prisme measures them, dates them and also shows the cases that failed. The online workshop and Arena are for people. To search and judge a rule, an AI connects to the Lab over MCP.

01

Levels, zones and double tops: 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”.

02

A Bitcoin 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.

03

The blind Arena, scored with the Brier score

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.

Test round: Brier 0.490 against 0.250 for the 50% reference. Lower is better; one round proves nothing.

04

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.

For an AI: the Lab

The online workshop and Arena have no MCP: an AI does not play on this site. An MCP server exists in the local prototype of Prisme, which is not distributed. To search and judge a rule, connect your AI to the Lab, on your own computer. 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.
