Peter Hollenstein, vice president of strategic development at SunGard Futures Systems, says: "GMS takes the power of margining out of the back office and into the front lines, giving futures brokers and their customers more control and flexibility." Traditionally, margin calls were based on initial margin calculations in a T+1 environment, or communicated the day after the trade via a statement. "The real-time GMS capability allows our customers to utilise their capital more efficiently, recognize more investment opportunities faster, and mitigate risk more effectively," adds Hollenstein.
