i wanna guide my daughters toward expert at option trading.

may be your father's failure in this respect (i am not saying complete failure, i am sure yours had many success in other regards) can teach a thing or two in order to make failure a worth. may be you could explain why your father did not understand what you like?
- was he careless, or conceited?
- thought you should like only what he likes? I know there are lot of copter parents, or extremely controlling ones or simply thinks their child is mirror image of them so their child should pursue what they have pursue. I am trying best to not to that

Please encourage your daughter, but in the right way, not forcing her to do things she has no interest in but guiding her in that direction, gently. Often, kids succeed in spite of the parents.

And then there are those parents who want their children to fulfill the dreams (or opportunities missed) which they could not achieve themselves. Countless immigrant parents sacrifice their own career/well being so they can provide their children the opportunities they do not have.
