6 SMA&look back 20SMA strategy6 SMA&look back 20SMA strategy
The moving average is calculated based on historical prices and is a backward indicator,Unable to forcast future prices.
But the moving average still represents the price trend, so we can forcast by moving average.
Each point of the 20-day SMA is calculated based on the closing price of the past 20 days.
Therefore, we can know that the closing price of the first 20 days directly affects the latest point of SMA.
The last 20 days are the prices included in the calculation, which directly affect the trend of the latest points.
For example,if the day before the 20th is a sharp fall, the latest SMA becomes an upward trend;If the day before the 20th is a sharp rise, the latest SMA becomes a downward trend，it showing the opposite trend
Recommended to use the daily trend.
Good Luck
移動平均線是根據歷史價格計算，屬於落後指標
但是移動平均線仍代表價格趨勢，因此我們可以通過移動平均線進行預測。
20天均線的每個點都是基於過去20天的收盤價計算的。
因此，我們可以知道前20天的收盤價直接影響SMA的最新點。
最近20天是計算中包括的價格，它直接影響最新點的趨勢。
例如，如果20日之前的一天是急劇下跌，則最新的SMA成為上升趨勢；如果20日之前的一天是急劇上漲，則最新的SMA成為下降趨勢，呈現相反的趨勢。
