I created the bookmark the moment the dashboard appeared for the first time. The page was still loading the lower markets when I saved it. The bookmark sat at the top of the browser list and became the only way I opened the site for the next week.
On the second day the bookmark loaded directly into the dashboard without showing the login screen again. The browser had kept the session. On the third day the login screen reappeared and required the credentials once more. The pattern continued without a fixed rule. Some days the session survived. Other days it did not.
What the bookmark removed
Typing the address every evening disappeared. The single click became automatic. I used matchexch9 co only through that bookmark and stopped entering the full string by hand. The small saving of effort made the opening step quieter.
A closer look at the days the session survived
The days when the dashboard opened directly were the ones when I had not closed the browser completely the night before. Leaving the browser in the background seemed to preserve the login. Fully closing it returned the login screen the next time. Once that link was clear I began leaving the browser open overnight on purpose.
Short replies when I mentioned the bookmark
I wrote one line about saving the page the moment it first opened. Two people answered that they had done the same. One said the bookmark sometimes opens an older cached version and needs a refresh. Another noted that he re-creates the bookmark every few weeks to keep it clean. The comments stayed brief.
One adjustment that remained
I now refresh the bookmarked page once before entering any credentials. The extra tap removes any chance of seeing outdated markets from a previous session. The habit takes one second and keeps the information current.
Creating the bookmark at the first successful login removed the need to type the address again. The session sometimes stayed open and sometimes required a fresh login. Once the pattern was visible the bookmark became an ordinary tool rather than a special step. The match itself decided how long the page remained open after that.
