Module 8 · Keeping Score Honestly Mastery
A practice account that made money has not necessarily done well, and one that lost money has not necessarily done badly. The honest test is whether your process beat the simplest alternative — owning an index fund and doing nothing — after the costs real life would have charged. This module builds that scorecard, and ends with what to do with the answer.

By the end of this module you'll be able to
- Compare a practice account against a fair benchmark, including a blended one.
- Estimate the trading, currency and tax costs a simulator leaves out.
- Tell whether a result is dominated by one lucky position.
- Build a practice scorecard and use a checklist before moving to real money.
Beat doing nothing
The right question is not “did I make money?” — in a rising market almost everyone does. It is “did my decisions add anything compared with the simplest thing I could have done instead?” That simplest thing is your benchmark.
The easiest benchmark is a single broad index fund. On the day you start, write down its price. Whenever you keep score:
Benchmark return = (benchmark price today ÷ price on your start date) − 1
Excess return = your total return − benchmark return
Worked exampleYour account is worth $108,000: a total return of +8%. An S&P 500 fund that was $500 on your start date is now $555: a benchmark return of +11%. Your excess return is 8% − 11% = −3 percentage points. You made $8,000 and still underperformed doing nothing by $3,000.
If your plan mixes US, Canadian and international holdings, a blended benchmark is fairer. With a 60% US / 25% Canada / 15% international target and index returns of +11%, +6% and +4%, the benchmark is 0.60 × 11 + 0.25 × 6 + 0.15 × 4 = +8.7%.
Compare like with like. The simulator does not credit dividends, so its returns are price returns. Compare them against the benchmark’s price change, as above — not against a published “total return” figure that includes reinvested dividends. Or add your dividend log from Module 7 to your side, and use the benchmark’s total return.
The costs the simulator ignores
A real account would have charged you for things the simulator did not. Estimate them before you compare:
| Cost | In the simulator | In real life |
|---|
| Bid–ask spread | Zero | Paid on every trade; small in large stocks, 1%+ in thinly traded ones |
| Commissions | Zero | $0 at many brokers; still charged at some |
| Currency conversion | None — CAD and USD treated alike | Commonly around 1.5%–2% each way at many Canadian brokers |
| Tax | None | Capital gains and dividends taxed outside a TFSA or RRSP |
| Fund fees (MER) | Already inside the fund’s price | Same — this one is not missing |
Worked exampleOver a year, a Canadian made ten round trips of $10,000 each in US stocks. At a 1.5% conversion cost each way, each round trip costs about $10,000 × 1.5% × 2 = $300. Ten of them: $3,000 — 3% of a $100,000 account, before any spread or tax. A strategy that beat its benchmark by 2 points in the simulator would have trailed it in real life.
Frequent trading has a tax trap too. In a taxable account, only 50% of a capital gain is taxable in Canada, but the Canada Revenue Agency can treat very frequent trading as a business, taxing gains fully as income — and that risk applies inside a TFSA as well.
Luck or skill?
Short records are mostly noise. Three months, or even a year, of results cannot reliably tell a good process from a lucky one. Two quick tests help:
- Remove the best trade. Subtract your single largest realized or unrealized gain from total return. If a winning record becomes a losing one, the result rests on one position — which could easily have gone the other way.
- Check the process, not the outcome. What share of your trades followed your written plan? A losing account that followed its rules 95% of the time has taught you more than a winning one that broke them every week.
A practice scorecard
Fill this in every quarter:
| Measure | How to get it |
|---|
| Total return | Account value vs $100,000, plus your dividend log |
| Benchmark return & excess return | Index price on start date vs today |
| Estimated real-life costs | Spread, currency and commissions per trade, added up |
| Maximum drawdown | Deepest fall from a peak on the equity curve |
| Win rate & average win vs average loss | From realized P&L in trade history |
| Return without the best trade | Total return minus the largest single gain |
| Plan adherence | Trades that followed the written rules ÷ all trades |
Win rate on its own misleads. What matters is win rate combined with the size of wins and losses:
Expectancy per trade = (win rate × average win) − (loss rate × average loss)
Worked exampleYou win 40% of your closed trades, with an average gain of $900, and lose 60%, with an average loss of $400. Expectancy = 0.40 × $900 − 0.60 × $400 = $360 − $240 = +$120 per trade. Losing more often than winning is perfectly compatible with a positive result, provided losses are kept small — and the reverse is true too.
Before you use real money
There is no certificate that proves readiness. But these questions are worth answering honestly and in writing:
- Do I have an emergency fund, and no high-interest debt, so I will never be forced to sell?
- Have I practised long enough to see at least one meaningful fall in my account, and did I follow my rules through it?
- After estimated real-life costs, did my approach beat — or at least match — a simple index fund?
- Do I know which account the money belongs in: a TFSA, an RRSP, an FHSA or a taxable account?
- Will I start with a smaller amount than I plan to invest eventually, and keep the same journal?
For many people, the honest answer from a year of careful practice is that a low-cost index fund beat their own picks after costs. That is not a failure of the exercise. It is one of the most valuable — and most profitable — conclusions an investor can reach, and it was reached for free.
