Strategy overview

Detrended RSI is a variant of the classic oscillator that removes the slow-moving baseline underneath the reading, so what remains is the oscillation itself rather than the drift it sits on. What makes this entry different from most RSI pages is that its source is not a setup tutorial at all: it is a test report. The video, "I Tested Detrended RSI… The Results Surprised Me" by Ali Casey on the StatOasis channel, opens with an introduction to the indicator and is framed around running it and reporting back — the object of interest is the tool, not a packaged strategy built on top of it.

That distinction matters when you decide what to take from a video like this. A channel that tests indicators is answering a narrower question than a channel that teaches one: does this transformation behave differently from the standard RSI, on the data the tester chose, over the period they chose? "The results surprised me" is a statement about the tester's prior expectations, not a performance claim you can carry over to your own market, timeframe, or execution costs — and any single test is bounded by its sample, its instrument, and the specific definition of "detrended" the tester implemented, since the term covers more than one construction.

No trading rules, parameters, or settings were extracted from this source, so this page is an indicator entry rather than a decoded rule set: it points to the concept and to where it was discussed. If Detrended RSI interests you, the useful first step is to pin down exactly which detrending construction you mean, then reproduce the comparison against a plain RSI on your own data before deciding whether the difference is worth anything to you.

Frequently asked questions

What is the Detrended RSI indicator?

It is a modified version of the Relative Strength Index in which the slower-moving baseline component is removed, leaving an oscillator that reflects the shorter-term swing rather than the underlying drift. Because "detrended" can be implemented in more than one way, the exact construction should always be checked against the source that describes it.

How does detrending change the way you read an RSI?

A standard RSI is bounded and is usually read against fixed levels such as 70 and 30. A detrended version typically oscillates around a zero baseline instead, which means the familiar overbought/oversold thresholds no longer map directly and readings have to be interpreted against the new centre line and the range the series actually produces on your data.

Does this page contain the rules from the video?

No. No trading rules, entry or exit conditions, or indicator settings were extracted from this source — the video is presented as a test of the indicator rather than as a step-by-step strategy, so this entry covers the concept and the source, not a rule set.

How should I evaluate an "I tested it" indicator video?

Treat the result as one data point tied to that tester's instrument, period, parameters and assumptions about costs, then reproduce the comparison yourself on the market and timeframe you actually trade. Strategy Decoder catalogues strategies and indicators discussed in video sources so you can see what was described and test it on TradingView rather than take a reported outcome at face value.
