It sounds like your mouse button was starting to fail. This can happen with any mouse, regardless of whether or not it's wired or wireless. I work on a computer all day, and I have to replace my mouse every 2 to 3 years. My advice would be to use whatever mouse feels the most comfortable to you and replace it at the first signs of failure. Also, check your trading platform. Many have settings that prevent you from taking too large of a position due to double clicking/fat fingered order entry.
Well any seasoned gamer/shooter wouldn't even think of using a cordless mouse. Those are for reading email. Also a wired internet connection is probably a good idea.
I use keyboard hotkeys, so I can't relate. But the thought of trading with a mouse and having no battery during a scalp with no other mouse around is scaring the shyte out of me rn
Did you test how long these batteries last? I have a similar one with the same batteries and the same outlook. Batteries last maximum 3 months. They mention however 30-Month Long Battery Life. All depends on how intensive you use that mouse. I use it more than 12 hours a day 7/7. And when I say use, I mean moving it, not just switch it on and click a few times every hour. 30-Month Long Battery Life: With Auto power-off function, On/Off switch, Smart sleep mode and battery life indicator, you might just forget this mouse runs on batteries. Features a battery level indicator: Never be surprised by low battery power again. The LED battery indicator warns you if the charge is running low.
I have this Logitech G602 which you can get for about $30 on sale. You can check the battery life and get low battery notifications on Logitech's when you install their supporting software. https://www.amazon.com/gp/aw/d/B00E4MQODC?psc=1&ref=ppx_pop_mob_b_asin_title
