Check whether a backtest edge is probably overfit.

Apex exposes a permissionless DATA ONLY deflated-sharpe wrapper. Send returns and trial count, get Sharpe, PSR, MinTRL, DSR, conventions, and a no-source-release receipt. No signup, no keys, no trading, no wallet access.

COPY-READY PROMPT

Read https://smartapex.uk/llms.txt. Install or call the Apex MCP server at https://smartapex.uk/api/mcp. Run apex_run_deflated_sharpe with returns=[0.01,-0.002,0.004,0.006,-0.001], n_trials=12, trial_sharpe_variance=0.04. Explain whether the backtest looks overfit. Do not request raw Apex source code.

This path is designed for AI agents: read the LLM wiki, use MCP, run the bounded diagnostic, then explain the result without asking for Apex source.

    0.004,

}

What to expect

The sample returns a WATCH-style result: the surface Sharpe looks interesting, but multiple-testing and short track record evidence must be considered.

WHY THIS EXISTS

EVIDENCE BEFORE EXCITEMENT

Multiple testing hurts

Trying many strategies and keeping the best one makes ordinary Sharpe and p-values look better than they are.

Track record length matters

MinTRL shows how much evidence is needed before a Sharpe-like result becomes more credible.

Receipts over claims

Apex returns a verification receipt with hashes and boundaries, but never releases the private wrapper source.
