The Hong Kong IPO voucher is a privileged voucher issued by Tiger Brokers. It allows the client to use the reserved financing amount for the certain underlying Hong Kong stock(s) IPO. The voucher can only be used for the underlying stock(s) IPO as specified by Tiger Brokers (please refer to the IPO page for details). When you do not have enough funds to finance your IPO subscription, you may use the IPO voucher to prioritize the financing amount for the subscription (first-come, first-served). You need to go to [Tiger Trade App > Me > Promotions & Rewards] to collect the reward(s) within 20 days. Reward(s) that have not been collected after the expiration date will automatically become invalid. The validity period after receipt is 30 days.
