Why now “build without writing”? The choice of no-code TradingView® indicator development 【Treviewer Create】#01

Hello! I’m Dan from Gogojan.

This is the popular interview series with our company president, Hayakawa, and our developers.

This time, to get to the core of the Treview Create we developed,Gogojan Engineer Director Matsuihas joined us.

Engineer Director with a PhD from Tokyo University

In graduate school, studied mathematics and engineering, especially graphs and functions.
From that curiosity, he became interested in chart analysis and the world of investment, and joined Gogojan.
In addition to Web-based programming languages, he is proficient in MQL4 and MQL5.

In the past,GogoJungle LABOhe solved many technical challenges as the sole official contact person.

Currently, as Engineer Director, he is responsible for system development and technical supervision.

Just connect the blocks to create Pine Script®. Treview Create — turning ideas directly into indicators without code

Treview Create

No coding required.
Simply connect blocks to intuitively create Pine Script® indicators for TradingView®.
From idea validation and learning to building original logic,
“I want to turn ideas into something immediately”is a practical tool for traders.

We will freely release the HMA×RSI signal indicator created with Treview Create.

[Viewer-exclusive Benefit] HMA & RSI signal (with JSON)

This is a free sample distributed exclusively to video viewers.
After entering the password, you can obtain the HMA & RSI signal and a JSON design blueprint,
and freely customize it in “Treview Create.”

Why you can create without coding, and benefits also for those who can code

First, in one word, Treview Create is a tool that lets you create indicators with visual operations even if you cannot code—am I understanding this correctly?


Gogojan Hayakawa


Reiatsu Matsui

Yes, that’s right. With just clicking buttons, code is automatically generated, reducing the burden of remembering or looking up function names.

Actually, the point that there are benefits even for people who can write Pine Script is important. Specifically, where are those benefits?


Gogojan Hayakawa


Reiatsu Matsui

For example, even a single moving average would require remembering a lot of function names like SMA and EMA. With the tool, you just choose and it’s generated, speeding up development.

I see. It’s not just “救済 for non-coders,” but also a time-saver for those who can code.


Gogojan Hayakawa


Reiatsu Matsui

That’s right. It also helps with learning. By looking at the generated code, it becomes easier to understand how to write it.

This time, for viewers only, Matsui-san has prepared a sign-indicator as well. The reception flow is via the password in the video.


Gogojan Hayakawa


Reiatsu Matsui

Yes. If you try it together with the tool, the creation flow will be easier to imagine.

Background of the developer Matsui and “Who do you want to use it

Matsui has a background in mathematics and programming, and is also a TradingView® user.


Gogojan Hayakawa


Reiatsu Matsui

Yes. I’ve studied math and programming for a long time. I use TradingView® regularly as well for analyzing individual stocks.

That perspective of “I’m someone who uses it too” seems directly linked to the reason for the tool’s existence. Who would you like to see use it?


Gogojan Hayakawa


Reiatsu Matsui

People who want to create original indicators but feel programming is difficult... and those who want to master TradingView® more.

TradingView® can be used across forex, stocks, indices, and cryptocurrencies, among others.


Gogojan Hayakawa


Reiatsu Matsui

That’s right. We also want to deliver our know-how to as many users as possible.

Was the impetus for development also the rising popularity of TradingView®?


Gogojan Hayakawa


Reiatsu Matsui

Yes. Within the company, it was felt, “This is hot,” and there was a move to create content that could be used here. Also, purely, we wanted people to experience the joy of creating.

The aim of adopting JSON, UI/manual details, and behind-the-scenes of development

In terms of development, how many people were involved?


Gogojan Hayakawa


Reiatsu Matsui

Three people. I built the demo and directed it; one person implemented it, and one did debugging and verification, and we completed it in about three months.

One memorable event was the “JSON read/write” feature. How did this become an official feature?


Gogojan Hayakawa


Reiatsu Matsui

Originally it was a debugging convenience feature for validation. As we discussed, it would be more convenient as an official feature, and it was approved unanimously.

There was also an explanation that JSON can be treated as a “design blueprint.” What are the benefits for users?


Gogojan Hayakawa


Reiatsu Matsui

You can save a partially completed indicator, share JSON with others for modification, etc. The manual also includes sample JSON, so users can reproduce it on their side for learning.

The UI details were also interesting. Color-coding and a flowing top-to-bottom structure help beginners avoid confusion.


Gogojan Hayakawa


Reiatsu Matsui

Yes. We categorized values as red and conditions as orange, and designed the flow to proceed from top to bottom to avoid clutter.

The manual was also crafted with a beginner in mind, and through making it, the specifications were refined.


Gogojan Hayakawa


Reiatsu Matsui

That’s right. We prepared a step-by-step flow, so it’s easy to notice what to learn next.
