When trading spreads and being stopped on shorts only, the longs remain in the account. Sometimes, cheap longs (0.05-0.10 $) may increase in value very much. For those not being able to track market movement all day: it would be useful to have a trailing TP order for those longs as of a certain threshold set by the user. Example: long bought for 0.10 $, goes up to 0.50 $ (minimum set by user), as of now trailing stop watches the option price and takes profit in case the price drops by x.x$ (for example 0.2$). The idea is to not let long profits go away again just because one cannot observe the option prices all day.
