Usury is 'Debt with Interest'.
Interest is defined as gaining specified amount of additional money from lending money with time.
It has a very clear definition.
Is option a debt? Are you in debt to somebody? Or are they indebted to you?
Are you paying interest, or are they paying you interest?
Trading something for profit is not interest.
If not, then it's not 'haram'.
For example, lending money, and add interests with indefinite span of time on tip, is considerend usury, as in Debt-Based Monetary system, or bank money-lending with interest.
It's not clearly defined with time, so the borrowers will have to pay infinite interest if things went south. It's a scam with exploitation at its core.
Lending money with a specified amount of fee is not usury. Because you don't trick or exploit anybody.
For example, You lend somebody 100k, and he'll pay back 120k, no matter if he missed the payment, or anything unfortunate happen.
You still make profit.
But there is no exploitation, because the contract is clear and definite, and the debtors is not hung on eternal interest that has now inflated beyond what is logical, like what happened with USA national debt.
So, are you in debt, and receiving interest on that debt?
If yes, then its haram.
If no, then its not haram.
