Parallel transactions involve bartering goods, but the contract between two parties and the seller includes obligations. In accordance with these obligations, it will be required to make mutual purchases within the stipulated period. Parallel transactions can be categorized into several branches: short-term offset transactions, mutual purchase agreements, and advance purchases.

A parallel deal is when an individual acquires two or more of the same financial assets with the anticipation of making a profit by reselling one of them at a higher price than the original purchase price.
