Thanks brian_z,

Thanks for your deep and details answers!

As you said, with AB we can only use stop loss feature.

However, Can we trade -off between loss and profit???
ex: if we invest into A (it's price may go up 80% and may go down 20%,
otherwise, if we invest into B (it's price may go up 30% and may go
down 70%) Should we should choose A, ect (Can AB helps us to follow
this kind of matters???)

I'am newbie so my thinking may be silly :D but it may help others.

(I'm not nature English speaker also :D So my writing maybe difficult
to understand) 

Thanks again
