Indicator Signals (RSI / MACD)

The claim: That crossovers and overbought/oversold readings predict the next move.

Our verdict · Did not survive costs

Flat out-of-sample probabilities — no directional signal at all.

01

How it actually works

Buy when RSI is 'oversold', sell when 'overbought'; act on MACD crossovers. The most-taught toolkit in retail trading.

We fed these features to a model and measured their out-of-sample predictive power directly.

02

We tested it

The predicted probabilities were flat — the indicators carried no out-of-sample directional information for the next move. Nothing to trade.

Every figure comes from this project's own out-of-sample walk-forward testing on real costs — the full research record is in the Lab.

03

What it teaches you

Indicators describe the past you can already see. That they're popular doesn't make them predictive — and measurement, not tradition, is the arbiter.

A perfect-looking pattern can still have no edge. The test, not the story, decides.
