Alright, so I'm back from the dead. Let's finish this cost-benefit analysis before the weekend. Here are back links for Part 1, Part 2, Part 3 in case you missed them. The table below shows my expected return as derived through part 2 and part 3 of this series. As you can see, I'm only expected to break-even by risking 1% of my \$5000 TFSA trading account. Trading just for the sake of break-even isn't exactly an enviable goal. Based on my statistics, I typically say an expected return of 0.10% per trade is acceptable. Looking at the table, that would require that I risk 1.5% per trade. [caption id="" align="aligncenter" width="570" caption="TFSA Trading Cost-Benefit for Reward/Risk = 2.0 and 40% win rate"][/caption] So I'll have to risk 1.5% just to scrape in 0.10% of profit? The problem is obvious. Using a \$5000 trading account with \$5 commission, along with my historical trading performance simply do not justify the odds. I started this series to study the cost effectiveness of a Questrade TFSA trading account. But the conclusion which I derived is much broader. Considering that even without being taxed, a \$5000 TFSA trading account is insufficient for trading with a commission of \$5 or higher. Thus, if this is a taxed, non-registered trading account, the cost would be even more. As such, not only is \$5000 an insufficient capital for a Questrade TFSA trading account; \$5000 is simply too little money to trade any trading account with \$5 of commission per trade for me. Remember though, this cost-benefit analysis is based on my own statistics. You can input your own parameters into this spreadsheet to get your own set of results. To be fair, I must clarify that the problem isn't with Questrade. Even with their lowest trading commission in Canada (affiliate link), a \$5 trading commission for an account of \$5000 is simply too much for me. Yes, there's nothing to stop you from trading with a \$5 commission for a \$5000 account. Heck, many have claimed to be successful with less than \$5000. However, that's just not my style. I don't gamble with my hard earned money. I only trade when the odds are in my favour. If the cost is un-proportionately high, it's as if I've suffered a setback even before I begin fighting the battle. As such, I'm going to say "no thanks!" to a Questrade TFSA trading account for now. My short term plan is to look for a guaranteed TFSA savings account until I can develop a trading system for Canadian stocks that would justify the cost-benefit.
