What is the legal ruling on dealing with international stock exchange offices that trade in gold, currency, and oil, where money is deposited with them in return for a monthly percentage ranging from 100-150 Jordanian Dinars, undefined or according to the office's monthly profit, and is this permissible with a condition in the contract to stop work and return the remaining capital when the loss rate reaches 10%?

It is permissible for the investor to pay money to offices if the relationship between them is one of an agent to a principal, provided that dealing is halted when necessary to avoid loss. However, dealing with international stock exchanges is generally impermissible, because they frequently involve forbidden contracts such as usurious and probabilistic contracts, and margin buying, unless their adherence to Sharia controls is known.
