    Convergence trade is a trading strategy consisting of two positions: buying one asset forward—i.e., for delivery in future (going long the asset)—and selling a similar asset forward (going short the asset) for a higher price, in the expectation that by the time the assets must be delivered, the prices will have become closer to equal (will have converged), and thus one profits by the ...
