I can’t stand it when I have a stock/ETF position and it’s not a nice rounded number.
E.g. 2354 of a certain stock (for instance due to stock dividend) drives me nuts. I’ll always drive for nice round numbers 500, 1000, 2500, etc. - not just to make options trading easier (writing covered calls) but also for esthetic reasons.
In the 2354 example… that would trigger me to buy a few more shares to get to 2500.
Do you have any irrational habits that you’re aware of and stick with?
