you can make a successful trade if you have some good information about the product which you are going to trad,, good trading skill and experience is also important tool of successful trading.
Of course information is needed for trading. Knowledge and skill not that, as you might get lucky. But you very need information what you trade, what it's price and so on
skill and luck is needed in trading. we have to have both, because the skill with no luck will not produce anything.
without skill , and luck will not make money.
Yes indeed both are necessary to succeed in the trade. We are required to have skills that can have a strategy in trade, so that we can predict with a good price so that could be an advantage. But luck is also needed because of the skill with no luck in my opinion would be futile.
