RDX (Risk Index) measures how one-sided the market action is. It doesn’t tell you whether price is going up or down — it tells you whether one side is completely dominating or whether both sides are evenly matched. High RDX means the market is heavily one-sided. Low RDX means the market is balanced.
Default period: 14
Line behavior: RDX ranges from 0 to 100. Near 0 means gains and losses are equal — the market is balanced. Near 100 means one side completely dominates. A smoothed line runs with it to show the underlying trend in risk.
Useful readings:
– RDX near 0 — the market is in equilibrium. Expect consolidation.
– RDX rising — one side is taking control. Directional risk is increasing.
– RDX above its smoothed line — risk is accelerating.
– RDX below its smoothed line — risk is moderating.
– Very high RDX (80-100) — the market is extremely one-sided. Strong conviction, but also potential exhaustion.
– RDX falling from highs — the dominant side is losing control. Trend may be tiring.
Objective rules:
– Watch for RDX rising from near-zero — this signals the start of directional risk and a potential new trend.
– When RDX is high and rising, the trend has strong conviction — ride it.
– When RDX peaks and starts falling, tighten stops — the move is losing steam.
– When RDX returns to near zero, expect consolidation or a new direction.
– Avoid entering when RDX is at extreme highs — the move may be overextended.
What makes it unique: RDX doesn’t predict direction — it measures imbalance. In a strong trend, high RDX isn’t danger; it’s conviction. It’s a pure gauge of how one-sided the action is, making it a powerful companion to any trend strategy.
