Multi-Timeframe EMA Levels and Linear Interpolation

Summary

This document describes a MetaTrader 5 version of EMA Levels that can display indicator values from timeframes other than the active chart. It supports the platform’s timeframes and offers automatic second- and third-higher-timeframe choices that adjust when the chart timeframe changes. The focus is on how multi-timeframe values appear across chart bars, rather than on entry or exit rules.

Interpolation replaces the usual step-shaped display with a smoother line between timeframe values. The document argues that this does not increase the number of exact indicator points: both display approaches have one guaranteed exact point per timeframe, while intervening values are repeated in the step display or estimated between points by interpolation. It suggests interpolated values may often better resemble values seen as the indicator developed, but offers no quantitative comparison or trading-performance evidence. The choice is therefore a charting and interpretation preference; interpolated values between confirmed timeframe points are estimates and should not be treated as additional exact observations.

Key ideas

  • The indicator displays EMA Levels from timeframes beyond the active chart timeframe.
  • Automatic second- and third-higher-timeframe settings change with the chart timeframe.
  • Interpolation smooths multi-timeframe displays by estimating values between exact points.
  • Both interpolated and step displays have one guaranteed exact point per timeframe.
