As an investor, it's important to track and analyze various statistics related to your trading performance. These metrics can provide insights into areas of strength or weakness, allow you to evaluate strategies, and identify opportunities for improvement.

Here are some of the most widely used trading statistics:

The profitability ratio, also known as the win rate, measures the percentage of your trades that are profitable. It is calculated as:

(Number of Winning Trades) / (Total Number of Trades)

For example, if you made 60 trades with 40 winners and 20 losers, your win rate would be 40/60 = 66.7%.

While a high win rate is desirable, even professional traders win on only 50-60% of trades. Focus on making your winners bigger than your losers rather than obsessing over a very high win rate.

Profit and Loss is the net capital gained or lost over a specified period through your trading activities. Tracking P&L is crucial for understanding trading performance.

Many trading platforms and journals automatically calculate separate P&L figures for individual trades as well as totals by day, month, year, etc. Analyzing granular and overall P&L numbers enables data-driven strategy adjustments.

Breaking down your results between buys and sells can reveal insightful differences.

Buy Trade Win Rate = (Winning Buys) / (Total Buy Trades) Sell Trade Win Rate = (Winning Sells) / (Total Sell Trades)

If one side consistently underperforms, it may signal the need for improving trade entry, exit, or trade management rules specifically for buys or sells.

Quantifying the average size of your winning trades versus your losing trades is insightful:

Avg Winner = (Total Winning $) / (Number of Winning Trades) Avg Loser = (Total Losing $) / (Number of Losing Trades)

Successful traders aim for an ratio greater than 1.5 or higher, meaning their average winner exceeds 1.5x their average loser. This allows offsetting losses while generating profits.

Maximum drawdown represents the largest peak-to-trough decline in your account value due to a series of losses over a given period. This statistic measures risk by showing your strategy's worst-case scenario.

For example, if your account grew from $10,000 to $15,000 before falling to $12,000 and recovering, your max drawdown was ($15,000 - $12,000) / $15,000 = 20%.

Lower max drawdowns are desirable, signaling less risk and smoother equity curves. Evaluating drawdowns helps with appropriate risk/money management.

By tracking and analyzing these key statistical measures of your trading activities and results, you can gain a more objective view of your performance, strengths, and weaknesses as a trader. This quantitative feedback loop enables continuous learning and refinement of your strategies over time.
