EMA 100

EMA 100

EMA 100 is a 100-period exponential moving average used to identify longer-term trends and filter short-term noise.

The 100-day Exponential Moving Average (EMA-100) calculates a weighted average of closing prices over 100 days, with recent prices receiving greater emphasis than older prices. This intermediate-to-long-term indicator bridges the gap between shorter-term EMAs and the critical EMA-200, providing additional context for medium-term trend analysis with faster response than the equivalent SMA.

The EMA calculation:

Multiplier = 2 / (Period + 1) = 2 / 101 = 0.0198 (2.0%)
EMA = (Today's Close × Multiplier) + (Yesterday's EMA × (1 - Multiplier))

Why EMA-100 matters:

  • Medium-term trend: Shows direction over approximately 5 months
  • Between EMA-50 and EMA-200: Additional confirmation level
  • Faster than SMA-100: Responds more quickly to trend changes
  • Support/resistance: Can act as significant price level

Interpreting EMA-100:

  • Price above EMA-100: Medium-term uptrend is intact
  • Price below EMA-100: Medium-term downtrend in place
  • Rising EMA-100: Sustained positive momentum over several months
  • Falling EMA-100: Sustained negative momentum

EMA-100 in moving average hierarchy:

  • EMA-50 above EMA-100 above EMA-200: Strong bullish alignment
  • EMA-50 below EMA-100 below EMA-200: Strong bearish alignment
  • Mixed positions: Transitional phase; exercise caution

Trading applications:

  • Trend confirmation: Price above EMA-100 confirms intermediate uptrend
  • Support testing: Watch for bounces off EMA-100 in uptrends
  • Multiple EMA analysis: Combine with EMA-50 and EMA-200
  • Breakdown signals: Break below EMA-100 may precede larger moves

EMA-100 vs. SMA-100:

  • More responsive: Reacts faster to trend changes
  • Earlier signals: Crossovers occur sooner
  • Tighter tracking: Stays closer to current price action

Limitations:

  • Less widely followed: Not as popular as EMA-50 or EMA-200
  • Significant lag: Still slow to react despite EMA weighting
  • False signals: Can whipsaw during extended consolidations

EMA-100 provides valuable intermediate-term context, particularly useful when EMA-50 and EMA-200 give conflicting signals. It adds another perspective for confirming trends and identifying potential support and resistance levels.
