What ASSAY found

5 defects

The observed break-even is higher than the design promisesfatal The declared geometry demands a 67.8% hit rate; the observed one demands 83.7%. A gap of +15.9 points that comes not from the signal but from rounding, slippage and fees.

There is no gross edge to discount costs fromfatal Average gross result is -0.595747: the strategy loses before paying any fees. Cost is not the problem, and removing it would not make it viable.

The real hit rate falls short of the observed break-evenmaterial Hit rate 79.3% against an observed break-even of 83.7%: it would clear the declared bar (67.8%) but not the real one.

What ASSAY cannot verify

Scope of the examination

Declared configuration against what actually ran Cannot be checked: no configuration was provided. This test compares the declared levels against the executed ones: without the configuration file there is nothing to compare

A test that cannot look is not a test the strategy failed. It is set aside, and it does not count against the result. Each missing field lights up one line of the spectrum.

Detail with evidence

D1-1 — The observed break-even is higher than the design promisesfatal The declared geometry demands a 67.8% hit rate; the observed one demands 83.7%. A gap of +15.9 points that comes not from the signal but from rounding, slippage and fees. EVIDENCE — ft_Bandtastic.csv: multiple computed from the stop, n=516 · test D1

E4-1 — There is no gross edge to discount costs fromfatal Average gross result is -0.595747: the strategy loses before paying any fees. Cost is not the problem, and removing it would not make it viable. EVIDENCE — ft_Bandtastic.csv: 516 trades · test E4

D1-2b — The real hit rate falls short of the observed break-evenmaterial Hit rate 79.3% against an observed break-even of 83.7%: it would clear the declared bar (67.8%) but not the real one. EVIDENCE — ft_Bandtastic.csv: 409 winners out of 516 · test D1

L-11 — Column 'enter_tag' is entirely emptyminor 516 rows, 516 empty. The column is declared but holds nothing. EVIDENCE — ft_Bandtastic.csv: column 'enter_tag' · test F1

F2-3 — One value dominates 'trade_duration'minor The value 600 appears in 218 of 516 rows (42.2%) across 86 distinct values. Consistent either with a default filler or with a design level; the two need telling apart. EVIDENCE — ft_Bandtastic.csv: column 'trade_duration' · test F2

What the engine assumed when reading the file

Declared column mapping

A column name is a claim by the client, not a fact. The engine infers each column's role from its contents and states it openly. If that reading is wrong, everything above must be revisited.

What this report does not say

What this number measures: what fraction of what the strategy CLAIMS is still standing after scrutiny. What it does not measure: future returns, probability of success, or the quality of the idea. A test can score 3/3 on a strategy that loses money: it means it loses in a way consistent with what it declares. This is backward-looking. A 24 of 24 would not be investment advice.

ASSAY finds problems. It does not certify that a strategy works and it issues no return forecasts. A favourable verdict means the tests applied failed to break the result, not that the result will repeat.

A high karat count means nothing if barely anything could be checked: it is obtained by not testing. That is why both figures are always published together. Every figure comes from a test run against the file provided and can be regenerated; whatever could not be assayed is declared as such.
