Episode 4: Encounter with the Weapon Called Backtesting
BuilderOU STORY｜Episode 4
What a Backtest Is
The Encounter with a Weapon
Verification may seem roundabout,
but it was the shortest route
Hello.
I am
Mr. Ojun from BuilderOU (Builder King).
In Episode 3,
I talked about how I kept searching for a winning system,
and how I had started to apply it in practice without even testing it.
.
Every time I lost, I doubted the settings,
looked for another product,
and bought it again.
For a long time,
I believed that
“finding something that wins”
was the shortcut to success.
But what was truly necessary
was not to believe in someone’s words,but to verify it for myself.
1. The Moment I First Learned About Backtesting
With past charts,
you can verify your own method.
It was shocking.
At one point, I
learned the word
backtesting.
Using past charts,
if you traded under the same conditions,
you could confirm what the results would be
beforehand.
Number of wins.
Number of losses.
Longest losing streak.
Capital rise and fall.
Markets favorable to winning.
Markets prone to losses.
All of these can be confirmed
not by feel but by numbers.
For me,
this was a discovery that overturned the conventional wisdom I had.
2. The Days I Manually Verified Past Charts
Continuous, steady work
to protect my future self
was something I believed in.
It wasn’t that I could use handy tools from the start.
