Permissible first
A company must pass the Shariah screen before it can be bought, and keep passing it to be held. Business activity, debt, cash and interest income are checked against the thresholds the major Islamic indices use.
Disciplined by rule.
Balanced by design.
MARBIN is a private, rules-based system for trading Shariah-compliant equities in London and New York. A Shariah index fund as its base, two disciplined strategies on top, one risk engine, and a forecast engine that checks every call it makes against what actually happened.
Order, out of the noise.
- Debt under 33% of 24-month market value

- Every forecast checked against the result
- No leverage · no short selling
Two ways to work with MARBIN
One engine.
For people, and for the businesses that serve them.
The same Shariah screen, risk engine and forecast record run underneath both. Individuals see it at work in their own account; businesses use it, by the call, inside their own products.
For individuals
Your money, in your own account, managed by written rules.
A Shariah index fund as the base, a long-term core and short-term dips on top, every stop resting at the broker, zakat and purification worked out for you. Private and invite-only today.
How it works →For business
Shariah screening, data and white-label investing, by API.
For fintechs, brokers, Islamic banks, robo-advisers and charities: the screen, purification and zakat, signals and daily history, or a complete managed-investing service under your own brand.
Services and plans →Approach
Three convictions, written down
before the first trade.
Risk before return
Every order is sized from its stop, not from conviction. The stop comes from the stock’s own volatility and rests with the broker from the moment the order fills, whether or not the system is running.
Rules over impulse
Entries follow one written rule: a sound company, temporarily oversold, with no earnings report imminent and no red flags in the conversation around it. If any piece of data is missing, the answer is no.
Look inside
Nothing hidden.
Every rule written down.
The Shariah screen
Three ratios, excluded businesses, re-checked every morning at five.
The screen →The risk engine
Checks before every order, stops at the broker, limits that act when markets fall.
The engine →The track record
Every forecast recorded and checked, and results set against the index funds anyone could hold.
The record →Stay in touch
