A Python journal I built to give my weekly trade ideas and next-day plans a consistent structure,
now being developed into a Flask web app with a basic interactive interface.
Turning scattered trading notes into a repeatable process
As a trader, I wanted a quick way to record ideas without opening a large platform or rebuilding the
same note format every time. Weekly scans and aftermarket plans contain different information, but both
are easier to review when each entry follows a consistent structure.
I started with a Python command-line journal that saved formatted entries to local text files. I am now
building a Flask version with separate forms for weekly ideas and aftermarket scans. The current UI is
still basic, but it gives me a foundation for making the journal easier to use in the browser.
// Interactive Walkthrough
From a trade idea to a structured journal entry
This browser walkthrough recreates the weekly-idea flow. The real project runs locally and appends each
entry to a text file with the current date and time.

Complete the form and press "Save Weekly Idea" to format the entry.
Entry savedThe same format is appended to the local journal file.
Select a weekly trade idea or an aftermarket scan based on the type of preparation being recorded.
02
Enter
Provide the ticker and the details needed for that journal mode, such as bias, catalyst, or key levels.
03
Timestamp
Generate the current date and time automatically so every entry records when the plan was created.
04
Format
Turn the submitted values into a labeled, readable block instead of storing unorganized notes.
05
Save
Append the completed entry to a local text file so earlier plans remain available for review.
Challenge
Turning a terminal script into a web workflow
The project began as a small command-line program, but I want to make the same process easier to use.
While building the Flask version, I am learning how to connect HTML forms to Python routes, process
submitted fields, and preserve the journal's existing formatting and file-saving logic.
What I Learned
How Flask routes receive and process form submissions.
How to separate entry formatting from the interface that collects the data.
How timestamps and append-mode file writing support a running journal.
How a personal workflow can become a practical software project.
Current Limitations
Runs locally and stores entries in plain text files.
Does not display or search previous entries in the interface.
Does not calculate trade performance or journal statistics.
The Flask interface is still in development and currently has only a basic UI.
Future Improvements
Store entries in a database instead of separate text files.
Add an entry history with search and filtering.
Track outcomes, profit and loss, and recurring setup performance.
Add authentication before making the journal available online.
