Know the patterns of both loss and win
If you look back on the last 100 trades, you can see your loss patterns
Your losses actually occur in the same patterns every time.
It's important to review each trade one by one. But that's not all there is to see.What you can uncover are the "tendencies" and "patterns" of losses.
Even if you look at just one trade, you only know "this is why I lost this time." But when you review the past 100 trades together, a completely different picture emerges. “I always lose in similar situations in similar ways”—this common pattern rises to the surface.
Once you understand the loss patterns, you can take countermeasures. Conversely, if the patterns are not visible, you’ll think “this time was just a coincidence” and repeat the same losses. Looking back over past trades collectively is the strongest way to discover loss patterns.
Why review them in aggregate?
Reviewing things one by one and reviewing them all together reveal different insights.
Reviewing them one by one revealsindividual causessuch as “I entered this trade without checking higher timeframes and lost.” This is important in itself. But whether it’s just a one-off or a habitual habit cannot be determined from a single instance.
Reviewing all at once revealsrecurrent tendenciesIf, after looking at 100 trades, you realize that many losses occurred when you entered without checking higher timeframes, that is not just a coincidence but a clear weakness of yours. This insight cannot be obtained without reviewing in aggregate.
