Almost every other question here has two credible sides. This one mostly does not — which makes it the most useful place to see what riba actually is.
Buying on margin means the broker lends you money so you can hold a position larger than your cash covers, and charges interest on the balance until you close it. Strip the terminology away and there are two separate transactions stacked on each other: a purchase, and an interest-bearing loan that financed part of it. The purchase may be entirely fine. The loan is the problem, and it is the plainest form of the thing Islamic finance prohibits — which is why this page is short on qualifications compared with the rest of the series.
Riba in its clearest form is a predetermined increase paid for the use of money over time. A margin balance accrues exactly that: a published annual rate, charged daily on the borrowed amount, appearing on your statement as a financing cost. There is no interpretive distance to cover here, no analogy being drawn, and no significant scholarly disagreement. It is also worth noting where the prohibition attaches — paying it is prohibited, not only receiving it, so the fact that you are the borrower rather than the lender does not change the answer.
This is the practical trap. A COMPLIANT verdict on this site is a statement about a company — its business and its balance sheet, as set out in the methodology. It says nothing about how you paid for the shares. Buying a fully screened, debt-light, permissible business with borrowed money at 9% is a compliant asset acquired through a non-compliant transaction, and the screen has no way of knowing. The same logic runs through options, futures and short selling: the verdict travels with the issuer, never with the mechanism.
Brokers marketing swap-free, interest-free or "Islamic" leverage have removed the visible charge, and a well-established principle is what most scholars then reach for: every loan that draws a benefit to the lender is riba. The broker is not extending credit as a favour. It profits from the spread, the commission and the volume that the leverage exists to generate, so the benefit flows back to the lender by design even with the rate at zero. Two further features are worth examining on their own terms rather than assuming the label covers them: an administration or rollover fee that varies with the size and duration of the borrowing is the interest charge computed differently, and forced liquidation — the lender's right to sell your assets to protect its own position — is a condition attached to the loan that has no counterpart in a simple qard hasan. Some scholars accept genuinely benefit-free structures; the label alone settles nothing.
Everything on this page disappears in a cash account, and that is the useful takeaway rather than a consolation. Buying only what your own capital covers means no loan, no interest, no financing cost and no liquidation clause — the transaction is a straightforward purchase of an asset you fully own. It also removes the concern most often raised about short-term trading in general, since holding period is not itself the issue; leverage is what turns an ordinary purchase into something else. The cost is that positions are limited to real capital, which is the trade the prohibition is asking you to make.
The auto-trading side of this system sizes every position in cash and uses no margin or leverage by construction — not as a setting that could be switched on, but as the shape of the thing. Every published signal is a long, fully-funded position in a screened asset, tracked to a resolved outcome on Signals and aggregated on Performance. Your own broker account is the part this site cannot see: a compliant symbol bought in a margin account is still a margin trade. This is a research tool, not a fatwa — when in doubt, consult a qualified scholar.
