The tool

get_proof(ticker) returns, for a US stock, major ETF or major crypto pair:

NVDA — NO TRADE   (as of the 2026-08-14 session)
Price at that session: $225.01 (-0.07%)

Nothing to do yet. This only becomes a trade on a full daily close
above 227.49 or below 190.01 — until then it is stuck in the middle
of its own range.

PROVES IT WRONG:      $190.01
TURNS CONSTRUCTIVE:   $227.49

What it is not

It does not predict prices and returns no price target. It makes the assumptions behind a decision explicit before capital is committed.

NO TRADE and WAIT are returned unmodified — the tool will not launder a non-signal into a buy. If a symbol isn't covered you get a clear "not covered, and here's why", never a bearish read by accident.

Why you can check it

• We publish how often we're wrong — calibration, including the failures: https://www.compoundpulse.io/research
• Full trade record, losers included — https://www.compoundpulse.io/track
• Levels are fixed for the session and are not rewritten after the move, so any past call can be checked against what actually happened.

Most tools in this category publish neither. A score you can't audit is an opinion with a decimal point.

Privacy

Zero state, zero telemetry. This server is a thin proxy to a public endpoint — src/index.js is ~150 lines and there is no phone-home in it. Read it.

The underlying REST endpoint is public too, if you'd rather skip MCP:

Coverage

167 symbols: US mega/large caps, major sector and index ETFs, and major crypto pairs (-USD suffix). A verdict is only published with at least 25 completed daily sessions of real data behind it.
