if you talk about trading as in having your eyes glued to the screen, i fully agree - go seek professional advice. however, there are situations where you'd want to be able to trade or monitor the markets: [1] market timing you've been waiting for wave 5 of 5 of C to end in a multi-month correction (elliott-wave terminology) and it's time for a major turn in the markets. i would not want to miss that moment, even if i was on a 747. [2] ATS parameter adjustment you may want to oversee/supervise an automated system due to changes in risk-policy or market conditions (see pt 1) for instance.
you would want to do this if you are responsibly managing a position, but have to catch a flight. or perhaps awaiting a signal in your strategy that is about to happen. but in this particular case, i just wanted to try it, and test the waters should the need arise in the future. i do a lot of travelling, and the signals i watch happen approximately 2-3 times a month.
i agree with what u said that traders should trade so they can have a good lifestyle. it's allowed me to spend some time in spain, france, and italy the past couple of years. my strategy is implemented for the whole year. it's not 24/ 7 trading, but set-ups occur a couple of times a month. and i'd like to be there when they happen. of course, i can't control when they happen. sure, i could just walk away and not take the signals. but i see that as an opportunity cost. would you leave 50-100K lying on the table? perhaps not. and yes, i was chatting up a rather cute stewardess
