Is trading one's own money in buying and selling stocks, under the same conditions as Fatwa No. 90438, similar to gambling?

If trading through a broker is done with your own money, there is no harm in it, because it is a form of brokerage and is not combined with a loan contract. However, it is important to note that you should not only have the right to buy and sell, but also the ability to take possession of the goods and benefit from them. If this is not the case, it falls under conditions that contradict the essence of the contract and lead to gharar (excessive uncertainty/risk).
