Bollinger Band Crossovers with ATR-Based Trade Exits
Summary
This strategy combines Bollinger Bands with ATR-based risk controls to seek short-term trend changes and momentum shifts. It uses a 20-period simple moving average and a standard deviation multiplier of 2 for the bands. A move back above the lower band prompts a long entry, while a move back below the upper band prompts a short entry; the described orders use stop prices at the relevant bands and OCA grouping to manage competing entries.
The exit logic uses a 14-period ATR to set dynamic stop and target levels, with positions also closed on a reverse signal. The document provides the rule outline and source logic, but no measured performance results. It identifies false breakouts in ranging markets, slippage in fast conditions, parameter sensitivity, and overfitting as risks. Suggested refinements include trend or volume filters, additional momentum confirmation, adaptive band settings, and validation through backtesting and forward testing.
Key ideas
- The strategy uses a 20-period SMA and a two-standard-deviation setting to define Bollinger Bands.
- A price cross back above the lower band signals a long entry, while a cross back below the upper band signals a short entry.
- OCA order grouping and band-based stop entries are described as ways to manage directional orders.
- A 14-period ATR informs dynamic stops and profit targets, while reverse signals can close positions.
- Ranging markets, slippage, parameter sensitivity, and overfitting may undermine results.
