Simple Moving Average (SMA)

The Simple Moving Average (SMA) is a popular technical indicator that helps traders identify price trends. It calculates the average closing price of a stock or asset over a set number of days, smoothing out short-term price movements to make trends clearer.

• Significance & Purpose
  • Identifying trends – Shows if prices are moving up (bullish) or down (bearish).
  • Support & resistance levels – Prices often bounce off the SMA.
  • Generating trading signals – Helps traders decide when to buy or sell.
  • Reducing price noise – Makes price movements easier to understand.
  • Works best in trending markets (clear uptrend or downtrend).
  • Not effective in sideways markets, as price fluctuates around the SMA.

• How is SMA Calculated?
  • SMA = (Sum of Closing Prices over a Period) / (Number of Periods)
  • For example, if the closing prices over 5 days are 100, 102, 104, 101, and 103,
    • SMA (5-day) = (100 + 102 + 104 + 101 + 103) / 5 = 102

• Indicator Values & Interpretation
  • Short-term SMA (10, 20 periods) – Reacts quickly to price changes, used for short-term trading.
  • Medium-term SMA (50 periods) – Provides balanced signals, useful for swing traders.
  • Long-term SMA (100, 200 periods) – Shows major trends, used by long-term investors.

• How to Use It in Trading?
  • Trend Confirmation:
    • Price above SMA → Uptrend (bullish) → Buying opportunity.
    • Price below SMA → Downtrend (bearish) → Selling opportunity.
  • SMA Crossovers for Trading Signals:
    • Golden Cross (Buy Signal): Short-term SMA crosses above a long-term SMA → Strong uptrend.
    • Death Cross (Sell Signal): Short-term SMA crosses below a long-term SMA → Weakening trend.
  • Support & Resistance Levels:
    • Uptrend: SMA acts as support → Price may bounce up.
    • Downtrend: SMA acts as resistance → Price may drop further.
