Candle Dominance Index

Candle Dominance Index (CDI) is a sub-window histogram indicator for MetaTrader 4 that reveals the true conviction behind every candle — not just direction, but how hard bulls or bears dominated the full price range.

Most traders look at candle color and size. CDI goes deeper. It measures the ratio of the candle body to the total wick range, giving you an instant read on whether the move was decisive or weak. A tall green bar means bulls closed near the high — genuine strength. A tall red bar means bears closed near the low — genuine selling pressure. Short bars near zero expose indecision candles and fakeouts before they trap you.

How it works:
CDI calculates (Close - Open) / (High - Low) for every candle, normalized to a scale of -1 to +1.

• Green bar above zero — bullish candle; height shows how dominant the bulls were
• Red bar below zero — bearish candle; depth shows how dominant the bears were
• Values near ±1.0 — close was at the extreme of the range, maximum conviction
• Values near 0 — small body relative to wicks, weak follow-through, potential reversal

Use it to:

• Confirm trend strength before entering
• Spot exhaustion candles at key levels
• Filter out low-conviction signals from your strategy
• Read price action faster without cluttering your main chart
