anyone benefitted from tiger brokers promotion & bonuses?

I got some rewards such as commission-free trading after I opened a Cash Boost Account (CBA). With the CBA you get a 20,000 SGD credit limit which you can use to buy US, HK & SG shares even without using your own money.

However, you must pay in mthe money into your account or sell off the shares before the clearing settlement period expires.

I was able to buy some shares and when I noticed the price had gone up, I sold them before the settlement period expired so I didnt use any of my money.
