Strong Trend Candles

This indicator highlights trend candles using a mathematically grounded method designed to identify moments when the market is truly dominated by buyers or sellers

Up-Trend Candle (UP):

The open is close to the session’s low.

The close is close to the session’s high.

This structure reflects sustained bullish control from start to finish.

Down-Trend Candle (DOWN):

The open is near the high.

The close is near the low.

This reflects clear bearish control throughout the session.

Precise Definitions Used:
UP-Trend Candle:
Open ≤ Low + 10% of range
Close ≥ High - 20% of range

DOWN-Trend Candle:
Open ≥ High - 10% of range
Close ≤ Low + 20% of range

Here, the range is simply High - Low.

Why are the thresholds different (10% vs 20%)?
This is intentional and based on how markets behave:

The opening price tends to be precise and stable in trend days. A strong trending candle usually opens very close to one end (high or low), reflecting a clean start without hesitation.

The closing price, however, often pulls back slightly before the end of the session—even during strong trends—due to profit-taking or last-minute volatility.

That’s why the close is allowed more tolerance (20%), while the open is held to a stricter threshold (10%). This balance allows the indicator to be strict enough to filter noise, yet flexible enough to capture real trends.

✅ Why this is useful
Unlike vague candle patterns like "bullish engulfing" or "marubozu," this method focuses strictly on structure and positioning, not color or subjective shape. It isolates the candles where one side clearly dominated, offering cleaner entries for breakout, continuation, or confirmation strategies.

You can use this tool to:

Spot high-momentum price action

Confirm breakouts or directional bias

Filter setups based on strong market conviction

🔹 How it works

An Up-Trend Candle is detected when the open is close to the daily low and the close is close to the daily high.

A Down-Trend Candle is detected when the open is close to the daily high and the close is close to the daily low.

The thresholds for “close to high/low” are configurable through the Open % of Range and Close % of Range inputs.

🔹 How to use it

Candles are colored according to their classification.

Colors can be customized in the settings.

This tool can be applied in any timeframe.
