The 200 SMA on D1 is the institutional trend-line. Best timeframes: D1, W1. Key signals: Price above 200 SMA = long-term uptrend. Below = downtrend.

What Is the Simple Moving Average?

The arithmetic mean of price over a set period. Slower than the EMA but smoother — less noise, more reliable long-term trend identification. SMA adds up the closing prices of the last N candles and divides by N. Every price in the window counts equally. The 200 SMA on the daily chart is the single most-watched indicator in all of trading.
