My Terminal Trading Chart is live!

2026-06-10
Terminal Trading Chart in action with ROKU stock 2026-06-13

Finally my 2016 open source project Terminal Trading Chart is live!
…I never thought I’d write those words.

Back in 2016, I started a small experiment:
What if I could visualize buying and selling pressure directly inside a terminal, using nothing but Unicode and ANSI colors?

The idea was simple:

  • Green on top = buying volume
  • Red on bottom = selling volume
  • Thicker glyphs = higher volume
    Using only three glyphs: U+2502, U+2503 and U+2588

But life got in the way. The project stayed in a drawer. Unfinished.

Until now.

Thanks to Claude and DeepSeek AI, I was able to finally bring this vision to life. With their help, the code is clean, the logic is solid, and, most importantly, the signals are readable at a single glance.

Today, I’m releasing Terminal Trading Chart as open source.
I never expected to feel emotional about a terminal chart. But seeing those green and red columns light up with real volume data… yes, it moved me.
I’m curious: does it move you too?

⭐ Star it if you believe in minimalistic, signal-focused tools.

PragmataPro 0.829: Curly Git tree and new essential glyphs

2021-05-14

This version coming from my experience as web developer.
Often I exchanged colon (:) with semicolon (;) and sometime I had the suspect that L lowercase can be more distinguished using a new design. After this redesign I can work now more sure to avoid misinterpretations.

Terminal Trading Chart project

2016-07-06

A command line chart system based on Unicode glyphs

Today I released on GitHub my idea of a trading chart based on Terminal or other command line applications.

Terminal Trading Chart sample

The mixing of volumes data and prices data:
│ (Unicode U+2502) = small volumes
┃ (Unicode U+2503) = medium volumes
█ (Unicode U+2588) = big volumes
Red and green colors are used to have a more clear idea visually of the percentage of selling and buying contracts referred on a defined time.
The simplification of the chart through a small grid helps to find the right moment for investing.

Feel free to contact me if you are interested in using this unprecedented chart system
Feedbacks are welcome
