How do you determine the long-term trend on a daily price chart? Do you currently consider the S&Ps to be in an uptrend? Do you employ long-term trend filters in your trading?
I used to struggle with this... but then I realized (through education) it doesn't really matter. All that matters is that you have a well defined plan/edge and you follow it. There are as many methods as there are traders. To me trend is up if we are trading above a 20 period EMA.
A common way... slope of 200 day moving average... but not especially useful for taking trading risk most of the time
trading , good trading that is, shouldn't depend on this as it's impossible to do .. if one could determine a 'trend' one wouldn't need anything else - just an entry with the determined trend and you are a winner .. however some papers recommend trading 180 or 364 day high - your chances of winning will increase but it's too long for me personally..
