This strategy was decoded from a public trading video but did not clear Strategy Decoder's codifiability bar: the extraction could not pin the rules down precisely enough to be turned into a reviewable specification. It is kept here as a reference post-mortem rather than as a strategy you can trade or backtest.

Why this strategy was archived

The True Strength Index is a double-smoothed momentum oscillator: price changes are smoothed twice with exponential averages, producing a line that tracks trend direction and momentum with less noise than raw rate-of-change. It is typically read alongside a signal EMA for crossovers and against a zero line for regime. This entry covers Quantified Strategies' video "TSI Indicator Explained: Strategy, Backtest & Rules", which presents the indicator on gold (GLD) in the channel's characteristic register — indicator first, then the question of whether it actually holds up when tested.

**Why this entry is archived.** Our extraction scored this video below the codifiability bar. The structural pieces are there — the TSI and its EMA smoothing are identified, and the instrument is named — but the conditions that would turn them into a working system are referenced rather than specified: the parameter settings, the exact trigger that constitutes an entry, and the exit logic are not pinned down tightly enough for us to code and backtest the strategy without filling gaps by guesswork. An entry we cannot reproduce faithfully does not belong in the active catalog, and we would rather archive it than publish an approximation and call it the author's strategy.

**What it still offers.** As an explainer, it does the job well: it lays out what double smoothing is actually doing to the momentum signal, why that matters for the noise a single-smoothed oscillator produces, and it frames the indicator as something to be tested rather than assumed. That framing — treat the indicator as a hypothesis, then check it against data — is the part of the video worth your time, and it is the discipline most indicator content skips entirely. If you are researching momentum oscillators, read this as background material, and see the momentum and oscillator concept hubs in the active catalog for entries where a complete rule set was successfully extracted.

Frequently asked questions

Why is this TSI strategy archived?

Our extraction identified the indicators involved — the True Strength Index and its EMA smoothing — but not a complete rule set. Parameter values, the precise entry trigger and the exit logic are referenced without being specified closely enough to automate, so the video scored below the codifiability bar we require for the active catalog.

What is the True Strength Index (TSI)?

A momentum oscillator built by smoothing price changes twice with exponential moving averages. The double smoothing reduces the noise typical of raw momentum readings, and the resulting line is usually interpreted through crossovers with a signal EMA and its position relative to zero.

Is the video still worth watching?

Yes, as an explainer. It covers what double smoothing does to a momentum signal and treats the indicator as something to be tested against data rather than taken on faith — useful background even though the rules were not extractable.

Where can I find codifiable momentum oscillator strategies?

The active catalog and the momentum and oscillator concept hubs list decoded video strategies where full entry, exit and parameter rules were successfully extracted.
