Why not use AI? The reason for prioritizing accuracy
img
There are many tools nowadays that write code with AI, but I heard that Treview Tsuku-ru doesn’t use AI. Is that true?
youtubeサムネイル
GogoJungle Hayakawa
youtubeサムネイル
Reon Matsui
Yes. This time we didn’t use AI at all. We assemble Pine Script code via algorithms based entirely on rules designed by humans.
Why did you deliberately choose not to use AI?
youtubeサムネイル
GogoJungle Hayakawa
youtubeサムネイル
Reon Matsui
We prioritized being able to create the indicator exactly as designed, consistently in the same form every time. AI is convenient, but it can waver in the details.
So you prioritized accuracy and reproducibility.
youtubeサムネイル
GogoJungle Hayakawa
youtubeサムネイル
Reon Matsui
Exactly. The same block configuration will always output the same code. We valued that peace of mind.

Complex under the hood, simple to operate. Challenges from the development floor
img
From an implementation standpoint, what was particularly challenging?
youtubeサムネイル
GogoJungle Hayakawa
youtubeサムネイル
Reon Matsui
Since we’re not using AI, the hardest part was outputting bug-free Pine Script via algorithm.
Hayakawa: That must have required some very fine adjustments?
youtubeサムネイル
GogoJungle Hayakawa
youtubeサムネイル
Reon Matsui
Yes. We implemented it while verifying each function’s specifications one by one.
That’s an effort users won’t see, isn’t it?
youtubeサムネイル
GogoJungle Hayakawa
youtubeサムネイル
Reon Matsui
Right. For users, the most important thing is being able to build intuitively, so we hide all the complexity behind the scenes.
I also heard you put thought into selecting the functions.
youtubeサムネイル
GogoJungle Hayakawa
youtubeサムネイル
Reon Matsui
We carefully selected commonly used and easy-to-apply ones to create a setup that avoids confusion at the first step.

Why the developers themselves wanted to use it

Mr. Matsui, what do you personally like most about Treview Tsuku-ru?
youtubeサムネイル
GogoJungle Hayakawa
youtubeサムネイル
Reon Matsui
The barrier to testing ideas has dropped dramatically.
Is there any benefit for those who can write Pine Script as well?
youtubeサムネイル
GogoJungle Hayakawa
youtubeサムネイル
Reon Matsui
Yes. Even without looking up syntax, you can assemble blocks and get it into shape, so you can test ideas easily.
As a developer, has it become a tool you want to use yourself?
youtubeサムネイル
GogoJungle Hayakawa
youtubeサムネイル
Reon Matsui
Yes. It’s a tool I feel I’d use routinely, so I can recommend it with confidence.
Lastly, a message to our viewers and readers, please.

Its strength is being able to turn your ideas into form on the spot, immediately. We hope you’ll enjoy using it.
