I think your mother would very much love to fulfill your own dream and not hers. But, if you have the same dream then it gets easier.
Your father is trying to give you an education so you can provide for yourself, I don't think they want you to be responsible for them if ever the time comes that you get successful in life. I mean, that's how parents are.
Now you said you are trading. Are you sure about the path that you are taking? Even though you learned so much about it there are always chances that you might get rekt if the market won't fluctuate the way you like it. There's still risk involved in it and you will need money for your capital which means spending, so where will you get that money?
Don't get me wrong I am not bringing you down, it's just that you said you are still a student and I do believe your father can still manage it for your education. If you can save some money by working a little then good, but don't force it and try to finish that education first. It will be the best gift you can give to them.
