Using Higher-Timeframe Bollinger Bands on Lower-Timeframe Charts

Article MQL5 code base

Summary

This indicator displays Bollinger Bands calculated on a higher timeframe over a lower-timeframe chart. Its settings cover the band period, deviation, applied price, source timeframe, drawing style, middle-line visibility, and optional alerts or notifications. The bands can be drawn as steps or as sloped lines between values from neighboring bars of the higher timeframe.

The document says signals occur when the current close moves beyond the upper or lower band. Its examples show H4 or H8 bands displayed on an H1 chart, but provide no performance results, entry or exit rules, or risk controls. The description also does not specify whether a band crossing should be interpreted as a breakout, a reversal, or simply a prompt for further analysis; traders would need to define and test that interpretation themselves.

Key ideas

  • The indicator overlays Bollinger Bands from a selected higher timeframe on the current chart.
  • Band calculation settings include period, deviation, and applied price.
  • The display can use step-style or sloped lines, with an optional middle band.
  • Alerts and notifications can be enabled through adjustable settings.
  • The stated signal occurs when the current close moves beyond either outer band.
