A couple of weeks ago I was casually chatting with a friend, masks on, social distance, the usual stuff. He was telling me how he was trying to, and I quote, detox from the broker app he was using. I asked him about the meaning of the word detox in this particular context, worrying that he might go broke, but nah: he told me that he was constantly trading. “If a particular stock has been going up for more than one hour or so and I’m already over the 1% profit threshold then I sell”, he said, “among other personal rules I’ve been following”. Leaving aside the slight pseudoscientific aspect of those rules, I understood what he meant by detox: following them implied checking the phone an astronomically high number of times.
