You should consider consulting a qualified tax expert with relevant experience (i.e. for corporations involved in investing/trading.)
FWIW, it's quite possible that conducting your trading inside of a corporation might not save you any tax at all. Have a look at this article: The Blunt Bean Counter: Should your Investment Income be Earned in a Corporation. One key point from that article:

However, the Small Business Deduction requires the corporation to have active business income. Income from specified investment businesses only qualifies as active business income in certain cases. A qualified tax expert will know best.
