Multi-timeframe context

By the end of this lesson you can

  • Establish which timeframe your question lives on before opening any chart
  • Explain why a signal has a horizon, and why reading it on another one discards its content
  • Resolve conflicting reads across timeframes with a stated hierarchy rather than by preference
  • Recognize timeframe shopping, and the specific way it manufactures confidence

This lesson opens with The five-day horizon in the support and resistance study.

What happened
The Federal Reserve Bank of New York study covered in S203-03 tested support and resistance levels published by six foreign exchange firms between 1996 and 1998, and found strong evidence they helped predict intraday trend interruptions. The result carried a horizon: for most firms the predictive power of the published levels persisted at least five business days beyond publication. The measured effect was an intraday one, tested at that scale, and the persistence result bounds how long the information remained useful rather than extending the finding to longer-horizon decisions.
The decision point
A tested signal comes with the timescale it was tested on, and that timescale is part of the finding rather than an incidental detail. Taking a result established for intraday trend interruptions and applying it to a position held for months is not a conservative use of the same information; it is a different claim, unsupported by the study, wearing the study's credibility.

What you will be able to answer

  • What decides your timeframe?
  • Why does a signal have a horizon?
  • How do you resolve conflicting timeframes?
  • What is timeframe shopping?

Orientation and Year One are open: anyone can read them without an account. From Year Two onward the lessons are for enrolled learners, because progress through the later years only means anything if it is tracked against a record.

It is free. We do not sell the list and there is nothing to buy at the end of it.

Contested

The five-business-day persistence result is specific to the levels, firms, currencies and period studied. It is used here to establish that findings carry horizons, not to suggest five days is a general figure for anything.

Whether higher timeframes should always govern lower ones is a convention rather than a finding, and practitioners disagree. This lesson's position is that the governing timeframe should match the decision horizon, which is a weaker and more defensible claim than the usual hierarchy rule.
