that is a decision to pursue a positive feedback trading strategy.

这其实是个追逐正反馈交易策略的决定
That is a decision that the more the position moves in your favor,

即越多仓位向你偏好的方向移动
the more your option is in-the-money,

你的期权的内在价值才能越高
and the larger is your exposure to the underlying stock

你的标的股票或者是你的标的货币
or the underlying currency.

获利才能越多
Anyone who chooses to use options as a trading vehicle

任何选择将期权作为交易媒介的人
is choosing an approach

都是在选择一种方式
in which they are going to increase the magnitude of their position

在价格升高时增加仓位
as the price rises or decrease the magnitude of their position

而在价格下跌时
as the price falls again,

降低仓位
exactly the opposite of the natural, stabilizing response.

完全与自然相悖请稳定情绪
A final source of this kind of positive feedback
