Lancelot Band - ATR Reversal+Trending Indicator
Sep 6, 2019

The Lancelot Band indicator provides a comprehensive framework for identifying potential price reversals and trending market conditions by combining elements of the Ichimoku Cloud and Keltner Channels. It utilizes a central baseline derived from Donchian calculations surrounded by multiple ATR-based bands to define volatility zones.
Usage
The indicator can be applied to various trading styles, including reversal and trend-following strategies:
Reversal Strategy
- Long Entry: Occurs when the price crosses over the Lower band. A stop loss can be placed at the xLower band.
- Short Entry: Occurs when the price crosses under the Upper band. A stop loss can be placed at the xUpper band.
Trend Following Strategy
- Long Entry: Triggered when the price crosses over the xUpper band. A stop loss can be positioned at the Upper band.
- Short Entry: Triggered when the price crosses under the xLower band. A stop loss can be positioned at the Upper band.
The indicator is most effective when used on liquid pairs such as BTCUSD or major forex pairs. It is recommended to use the Lancelot Band in conjunction with volume indicators or secondary exit signals to refine trade management.
Details
The script is constructed using a central baseline, which is the midpoint of the highest high and lowest low over a specific period (similar to the Ichimoku Kijun-sen). Around this baseline, four bands are projected based on the Average True Range (ATR):
- Upper/Lower Bands: Calculated using a 1.0 ATR multiplier from the baseline.
- xUpper/xLower Bands: Calculated using a user-defined ATR multiplier (defaulting to 1.5) from the baseline.
The color of the bands dynamically shifts between green and red based on whether the closing price is above or below the central baseline, providing an immediate visual cue for the current market bias.
Settings
- Base Line Periods: Determines the lookback period for the central Donchian baseline.
- ATR Mult: Adjusts the multiplier for the outer extreme bands (xUpper and xLower).
- ATR Periods: Sets the lookback period for the Average True Range calculation.
FAQ
How do I use the Lancelot Band for trend trading? You look for price breakouts above the xUpper band for long trends or below the xLower band for short trends, using the inner bands as trailing stop-loss references.
What timeframe is best for this indicator? While it works on various timeframes, it is designed for liquid assets where ATR and baseline calculations provide more stable volatility measurements.
