Trailing Stop Loss (動態止損）

最近漲的不錯，有點太好了。

舍不得賣，又沒有時間時時刻刻盯著，那就設個止損點。

可以有靜態（固定數字），或者動態。

通常1-2個ATR就可以。

A trailing stop is designed to protect gains by enabling a trade to remain open and continue to profit as long as the price is moving in the investor’s favor. The order closes the trade if the price changes direction by a specified percentage or dollar amount.
