How Do Moving Averages Work?
SMA Formula
SMA = (P1 + P2 + ... + Pn) / n. Equal weight to each price in the period.
EMA Formula
EMA = Price × (2/(n+1)) + PrevEMA × (1 - 2/(n+1)). More responsive to new data.
Crossover Signals
Price above MA = uptrend. Shorter MA above longer MA = bullish. Opposite = bearish.

How do I use MA for entry and exit?
Buy when price crosses above MA or when shorter MA crosses above longer MA. Sell on opposite crossovers. Use MA as dynamic support (uptrend) or resistance (downtrend).
What is MACD and how does it relate to moving averages?
MACD (Moving Average Convergence Divergence) uses 12 and 26-period EMAs. The MACD line = 12 EMA - 26 EMA. Signal line is 9-period EMA of MACD. Crossovers generate buy/sell signals.
