I’ve been doing some manual trades now and then. Was at the gym this morning and thought to buy an equity.
Dumb thing to do: Sent in the request from my iphone, accidentally multiplying the amount by 10x. I ended up long with a 600K$ position that did not want. For whatever reason could not manage to put in the sell from the phone and was getting worried that I could not properly monitor the appropriate exit. Had to leave mid-exercise and handle.
Luckily exited with a few thousand in profit, but could have gone the other way.
