Using a 34-Period EMA Wave and GRaB Candles to Read Trend Conditions

Article ProRealCode

Summary

This indicator combines a three-line exponential moving average channel with candle colors based on where the close falls relative to the channel. The upper, centre, and lower lines are calculated from the high, close, and low using a 34-period lookback. Closes above the upper line signal bullish momentum, closes below the lower line signal bearish momentum, and closes within the band indicate a neutral or transitional condition. Candle body direction also changes the displayed shade.

An optional ribbon adds a stricter state: a bar entirely above the upper line marks an uptrend, one entirely below the lower line marks a downtrend, and other bars are neutral. The lines, candle colors, and ribbon can each be toggled, and the lookback can be adjusted. These chart rules provide visual trend context, but the document gives no tested entry, exit, or risk rules and no performance evidence. Its interpretation of channel breaks as momentum should therefore be treated as an indicator description, not proof of predictive value.

Key ideas

  • The EMA channel uses separate averages of high, close, and low prices with a 34-period lookback.
  • A close above or below the channel is colored as bullish or bearish, while an in-channel close is treated as neutral.
  • Candle direction affects the shade used for the display.
  • A bar entirely above or below the channel determines the optional trend ribbon state.
  • The indicator describes chart conditions but supplies no tested trading rules or performance evidence.
