Strategy overview

RSI is a bounded momentum oscillator that measures the speed of recent gains against recent losses, and RSI-2 is its aggressive short-lookback cousin — a two-period version popularized for fast mean-reversion entries that reach extremes far more often than the standard 14-period reading. This entry, decoded from Ali Casey's StatOasis video "Is This the Best Strategy Filter You've Never Used? (Ultimate C%)", is not really about RSI on its own: it pairs that quick RSI-2 base with an unfamiliar custom oscillator — the Ultimate C%, or Casey C% — and asks whether bolting it on as a filter makes the underlying system better.

The distinguishing idea here is the filter, not the entry signal. A filter does not open trades; it sits on top of a base strategy and only lets through the signals that also meet its condition, in the hope of screening out the weakest ones. The Ultimate C% is presented as a smoothed, percentage-based oscillator, and the video's whole arc is empirical: it builds the indicator inside StrategyQuant X, layers it onto an existing daily strategy, and then runs a direct comparison between the filtered version and the original to see whether the extra condition actually earned its place. That best-vs-original question is the honest test any filter deserves, and it is where the source spends most of its time.

No mechanical rules were extracted from this video, so treat this page as a concept-and-source explainer rather than a ready-to-run system. The takeaway is the workflow — start from a base like RSI-2, add a candidate filter, and let a side-by-side test decide whether it belongs — not a fixed set of thresholds. Anyone curious about the Ultimate C% will get the most from watching how Casey defines it and stress-tests it against the unfiltered baseline.

Frequently asked questions

What is the Ultimate C% (Casey C%) oscillator?

It is a custom, smoothed percentage-based oscillator featured on the StatOasis channel. In this video it is used not as an entry trigger but as a filter layered on top of a base strategy, and the source demonstrates building and testing it inside StrategyQuant X.

What is RSI-2 and how does it differ from standard RSI?

RSI-2 is a two-period version of the Relative Strength Index. Because its lookback is so short, it reacts much faster and hits extreme readings far more often than the common 14-period RSI, which is why it is a popular base for short-term mean-reversion setups.

What does it mean to use an indicator as a "filter"?

A filter does not generate trades on its own. It sits on top of a base strategy and only allows through the signals that also satisfy its condition, aiming to remove the lower-quality ones. The video's core question is whether adding the Ultimate C% as such a filter improves the original system or not.

How can I tell if a filter actually improves a strategy?

Compare the filtered version against the unfiltered baseline on the same historical data — exactly the best-vs-original comparison the video runs. Strategy Decoder extracts the structure of strategies like this from video sources so you can evaluate the idea and test it on TradingView.
