Trailing Stop Loss (动态止损）

最近涨的不错，有点太好了。

舍不得卖，又没有时间时时刻刻盯着，那就设个止损点。

可以有静态（固定数字），或者动态。

通常1-2个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.
