A published investing rule, followed on paper.
A seyir is a ship's course, and the seyir defteri is its log. Here one momentum rule was published and sealed before the first decision; a paper portfolio of 100,000 USD follows it, every buy and sell recorded the day before it happens, and the page is regenerated each morning from that record. A research log, not investment advice.

Approach
Source, period and date are shown together.
Beside every figure sit its source, the period it belongs to and the date of the reading.
Missing data is stated plainly.
A cell with no data is drawn as an open mark; it is never taken for a zero.
The data is presented for comparison.
You can see where a figure stands among its peers and make the judgement yourself.
Only publicly available data is used.
The applications are built on publicly available data. No organisation's private data, code, documents or non-public knowledge is used.
I build these in my own time, on my own equipment.
The design, the data preparation, the code and the text are my own.
You can use the applications directly.
The links open the applications themselves, not screenshots.
