MT5 can provide a large amount of information about completed trading activity.
The challenge is that seeing the numbers is not the same as understanding what they mean.
A useful review should not focus only on whether the account finished with a profit or loss.
It should also consider how the result was produced, how consistent the trading was, what level of drawdown occurred, how frequently trades were taken, and how much historical evidence is available.
This guide explains the main areas to review when analysing MT5 trading history and why several metrics should normally be considered together.
Historical performance is descriptive, not predictive. The purpose of reviewing completed trades is to better understand what happened in the past, not to predict the outcome of future trades.
1. Start With the Number of Completed Trades
Before interpreting any performance metric, first consider how many completed trades are included in the history.
A result based on a very small number of trades should normally be interpreted more cautiously than a result supported by a broader history.
For example, conclusions drawn from 10 completed trades may carry less evidence than conclusions drawn from 100 or 200 trades.
That does not mean a small sample is useless.
It means the level of confidence in any conclusion should reflect the amount of evidence available.
There is no universal number of trades that automatically makes a trading history reliable.
The quality of the review also depends on factors such as:
- the type of strategy
- how often the strategy trades
- the period covered
- whether market conditions changed
- whether the trader followed a reasonably consistent process
The important point is to avoid treating a small sample as if it provides the same level of evidence as a larger and more representative history.

2. Review the Net Result
The net result shows the overall financial outcome of the completed trading history.
It is useful, but it should not be analysed in isolation.
A positive net result does not explain:
- how much drawdown occurred
- how consistent the results were
- how large the average win was
- how large the average loss was
- how frequently trades were taken
- whether a small number of trades produced most of the result
- how much historical evidence supports the conclusion
Two trading histories can produce the same net result while having very different underlying characteristics.
This is why structured performance review should normally consider several metrics together.
3. Examine the Win Rate
Win rate measures the percentage of completed trades that closed as winners.
A simple formula is:
Win Rate = Winning Trades ÷ Total Completed Trades × 100
Example:
If 40 out of 100 completed trades were profitable:
Win Rate = 40 ÷ 100 × 100
Win Rate = 40%
Win rate is easy to understand, which is why traders often pay close attention to it.
However, a high win rate does not automatically mean that a trading approach performed well.
For example, a trader may win frequently but experience occasional losses that are much larger than the average winning trade.
Another trader may have a lower win rate but larger average winning trades relative to average losing trades.
This is why win rate should normally be considered together with average win, average loss, expectancy, profit factor, and drawdown.

4. Review Profit Factor
Profit Factor compares gross profit with gross loss.
The basic formula is:
Profit Factor = Gross Profit ÷ Gross Loss
For example:
Gross Profit = $2,000
Gross Loss = $1,000
Profit Factor = 2.0
This means the completed trading history generated two units of gross profit for every one unit of gross loss.
Profit Factor can be useful when evaluating historical trading performance, but it should not be treated as a complete measure of trading quality.
Profit Factor alone does not explain:
- drawdown
- consistency
- trade frequency
- how results were distributed over time
- whether one unusually large trade had a major influence
- how much evidence is available
It should therefore be reviewed together with other performance measures.

5. Understand Expectancy and Expected Payoff
Expectancy describes the average expected outcome of a trade based on historical results.
A simplified expectancy concept considers:
- probability of winning
- average winning trade
- probability of losing
- average losing trade
One common form is:
Expectancy = (Win Rate × Average Win) - (Loss Rate × Average Loss)
For example:
Win Rate = 40%
Average Win = $100
Loss Rate = 60%
Average Loss = $50
Historical expectancy would be:
(0.40 × $100) - (0.60 × $50)
= $40 - $30 = $10 per trade
This does not mean the next trade is expected to make exactly $10.
It is a historical average derived from a group of completed trades.
MT5 reports may also display a metric known as Expected Payoff.
The terminology may vary slightly depending on the report format, but the key idea is similar: looking at the average historical outcome per trade.
Expectancy should be interpreted in the context of sample size, drawdown, trade frequency, and the distribution of results.

6. Compare Average Win With Average Loss
Average win and average loss provide another useful perspective on trading performance.
Example:
Average Win = $80
Average Loss = $40
In this example, the average winning trade is approximately twice the size of the average losing trade.
This relationship can help explain how a trading approach may perform even with a lower win rate.
However, averages also have limitations.
They may hide:
- unusually large winning trades
- unusually large losses
- different position sizes
- changes in market conditions
- inconsistent trading behaviour
For this reason, average win and average loss should be reviewed as part of a broader performance picture.
7. Review Drawdown
Drawdown describes the decline from a previous equity or balance peak to a later low point.
It provides context about the depth of historical losses experienced during the trading period.
For example, two accounts may both finish with the same overall return, but one may have experienced considerably larger drawdowns along the way.
Drawdown therefore helps explain the path taken to reach the final result.
It should not be viewed only as a negative number.
It is one part of understanding the historical risk and variability of completed trading activity.
Drawdown should normally be considered alongside:
- net result
- profit factor
- expectancy
- average win and loss
- consistency
- trade frequency

8. Look at Trade Frequency
Trade frequency shows how often trades were completed during the review period.
Frequency provides useful context because different trading approaches naturally operate at different speeds.
For example:
- one strategy may take only a few trades each month
- another may take many trades each week
Neither approach is automatically better.
However, frequency can affect how the trading history should be interpreted.
Trade frequency can influence:
- transaction costs
- market exposure
- sample size
- behavioural consistency
- how quickly evidence accumulates
A change in trade frequency may also be useful to review.
For example, a sudden increase in the number of trades may indicate a change in market conditions, strategy behaviour, or trader behaviour.
Frequency should therefore be considered as part of the wider performance context.
9. Review Consistency
Consistency looks at how trading results are distributed across the historical record.
Useful questions include:
- Were profits spread across many trades?
- Did one or two unusually large trades produce most of the final result?
- Were losses concentrated during one short period?
- Were results relatively stable or highly uneven?
- Did trade frequency change significantly?
- Did average trade outcomes remain reasonably similar?
Consistency does not mean every period must produce the same result.
Trading results naturally vary.
The objective is to understand whether the historical performance appears broadly repeatable in structure or heavily dependent on isolated events.
A consistency review should also consider the size of the available sample.
10. Review Several Metrics Together
This is one of the most important principles when analysing MT5 trading history.
No single metric provides a complete picture.
Consider two simplified examples.
Trader A:
- high win rate
- small average winning trade
- large average losing trade
- higher drawdown
Trader B:
- lower win rate
- larger average winning trade
- smaller average losing trade
- lower drawdown
If only win rate were considered, Trader A might initially appear stronger.
Once additional metrics are included, the comparison becomes more informative.
This is why performance review should normally combine several areas such as:
- net result
- win rate
- profit factor
- expectancy
- average win
- average loss
- drawdown
- trade frequency
- consistency
- sample size
The relationship between the metrics is often more useful than any single number.
11. Consider the Size and Quality of the Historical Sample
Historical analysis becomes more meaningful when the available trading history is sufficiently representative of the trading approach being reviewed.
A small sample may still provide useful information.
However, conclusions should normally be more cautious when the number of trades is limited.
The strength of the available evidence may also depend on:
- whether the same strategy was used consistently
- whether position sizing changed significantly
- whether trading conditions changed
- whether the history covers only one short market phase
- whether trades were manually or automatically executed
- whether the trader changed behaviour during the review period
The purpose is not to find a perfect sample.
The purpose is to understand how much confidence should reasonably be placed in the historical observations.
12. Historical Results Are Not Predictions
Historical trading analysis describes completed activity.
It does not predict the outcome of the next trade.
Market conditions can change.
Trader behaviour can change.
Position sizing can change.
Execution conditions can change.
A trading approach that performed in one period may perform differently in another.
Historical metrics should therefore be used as tools for understanding past performance, not as guarantees of future results.

Final Thoughts
Analysing MT5 trading history is not simply about checking whether the account made or lost money.
A more useful review considers how the result was produced.
That means looking at:
- completed trades
- net result
- win rate
- profit factor
- expectancy
- average win and loss
- drawdown
- trade frequency
- consistency
- sample size
When these metrics are reviewed together, they provide a clearer picture of historical trading behaviour.
They still do not predict the future.
They simply help explain the past more clearly.
