For an FX or CFD broker, the expensive moment is not the demo. It is the Monday open, the rate decision, the first suspicious deposit, the liquidity-provider change, or the support ticket that arrives while clients are trying to close positions. Finstek Limited's pitch is that a broker can rent a ready brokerage stack instead of stitching together trading screens, bridge software, back-office controls, risk dashboards, payment links, client onboarding, and 24-hour support from separate vendors. The attraction is speed. The price is dependence.
