Trading fees at TD waterhouse are $9.99 per trade for ordinary stock market trades, assuming you are a frequent trader or have at least $125,000 in combined assets in your accounts with them. I have a trading account for my RRSP, and another for my TFSA.
You can make some decent money trading without insider knowledge trading simply on momentum. Pick a stock with high daily trading volumes that you know won't collapse to nothing, and trade on the prices swings that happen continuously throughout the day. My favourite is Canadian big bank stocks - I can make money when theylre going up and when they\re going down simply because their prices swing considerably back and forth throughout the day, and at the end of the day, the banks will still be here. They also pay dividends that enhance both your dividend income and the degree of price swings on which you rely to make your money. Making $50 or $60 dollars on a trade doesn't seem like much, but if you do that a dozen or more times a day, it starts to add up pretty quickly. Besides, it's also plenty easy to make more than just that $50 or $60 per trade.
There is no one magic formula. You'll have to dedicate time to watching for the probable spikes and troughs. A moment's distraction and you could miss big opportunity. You'll have to work out your own strategy to trigger your buy and sells according to your own risk tolerance, and then stick to it. People lose money when they forget to stick to their strategy and get too greedy.
