I never slept particulary well, but trading most actively on US markets while living in the Far East, while beeing involved in markets in a few other timezones with school age kids and regulary day time obligations is wreaking havoc. Feel a wreck regulary during market hours, happily I'm not day trading and try to plan when in good shape (usually some hours I'll feel much more alert ) than stick to the plan as much as possible, sometimes while waking up every hour or so during market hours to check what's going on, and try to improvise less when feeling in a mess. I know some guys here daytrade from Asia btw and seem to enjoy it, I've actually lived at night for long periods, but it gets tougher with family obligations, and possibly with age ( or I'm simply a retard at adjusting my rithm to a regular 5am to 12/1pm sleeping time wich would work for most purposes here) Drinking plenty of coffee btw. Op from the information you shared in another thread , if I got the poster right, your issue is not only the monotony of the market but also having to wake up very early while going to sleep late. Oh... and the US soon gets into winter hours, it gets worse then.
