Moving Averages (MAs) are the most widely used technical indicators in the world. They smooth out price data to reveal the underlying trend direction. While price is noisy and zigzags constantly, a moving average gives you a clean line that tells you: 'Overall, is this stock going up, down, or sideways?' Institutional traders, mutual fund managers, and algo systems all use moving averages as core decision-making tools.

SMA(N) = (P₁ + P₂ + P₃ + ... + Pₙ) / N where P = closing price, N = number of periods
Pro tip — The 200-DMA is the most widely watched line in technical analysis — not because it predicts anything, but because so many participants act on it that it becomes self-reinforcing. Use it as a regime filter: above it, treat pullbacks as the default setup; below it, treat rallies with more suspicion and size smaller. It tells you which side of the market you are arguing with, nothing more.
