ACMI Crypto Market Breadth Oscillator – RS Breadth vs ACMI Index

📉 ACMI Crypto Market Breadth Oscillator

ACMI Crypto Market Breadth Oscillator chart combines the ACMI Index with a custom-built Breadth Oscillator based on Relative Strength (RS). It gives an instant read on market participation — telling you whether a majority of top cryptos are rising together, or if leadership is narrowing.

📊 What is the Breadth Oscillator?

You can think of it as a Relative Strength-based version of RSI, but applied to the entire market instead of a single coin.

It shows the percentage of coins in the ACMI index that are currently outperforming the index — i.e., having RS > 1.
This acts as a sentiment gauge — the higher the value, the more coins are participating in the move (broad strength); the lower the value, the fewer coins are leading (broad weakness).

The upper pane shows the ACMI index (blue) and the lower pane shows the % of index coins having RS > 1 (orange). Reference zones at 80 and 20 can help spot potential tops (broad euphoria) and bottoms (broad capitulation).

🧭 How to Interpret it?

Breadth % (RS > 1)	Interpretation
🔴 Above 80%	Nearly all coins outperforming – broad euphoria, potential top near
🟡 Between 20–80%	Neutral – mixed participation
🟢 Below 20%	Very few coins outperforming – broad capitulation, potential bottom near

Note: Similar to RSI, only high or low values do not mean reversal possibility. Breadth can remain high or low for long durations during a trend, similar to how RSI stays in OB/OS levels during strong trends.

✅ Why it Matters?

Spikes above 80% mean nearly every coin is outperforming — broad euphoria that often precedes tops / exhaustion.
Dips below 20% mean almost no coins are outperforming — broad capitulation that often marks bottoms.
Comparing this oscillator against the ACMI Index helps identify market health beyond price — whether the rally is broad-based or carried by a few large coins.
