EMA Percentage Channel and Bollinger Band Range Trading

Summary

This range-trading strategy uses a long-period EMA to define a percentage channel and Bollinger Bands to time entries. The published defaults use a 200-period EMA with a one-percent channel and 20-period Bollinger Bands. A long entry occurs when price crosses upward through the lower Bollinger Band while remaining inside the EMA channel; a short entry occurs on a downward crossing of the upper band under the same channel constraint. Positions close when price crosses the relevant EMA channel boundary, and ATR-based stop and limit orders are included in the source.

The method is intended for range conditions, with a related trend strategy suggested for trending markets. The published test settings cover one week of BTC/USDT futures on three-minute bars, but the document reports no test outcomes, so it does not establish stability or profitability. A channel that is too wide can delay exits, while a narrow one can increase trading frequency and costs. Bollinger and ATR settings also affect entry and risk behavior, making broader market and parameter testing necessary.

Key ideas

  • A 200-period EMA and a percentage offset define the channel used to constrain entries.
  • Bollinger Band crossings provide the long and short entry triggers while price remains inside the EMA channel.
  • The source includes ATR-based stop orders and Bollinger-based limit exits.
  • The strategy is intended for range markets and may be unsuitable during sustained trends.
  • Published test settings cover a short BTC/USDT futures sample, with no performance statistics reported.
