Hi MarketArt, very good question (maybe the one million dollar question).
The main problem is: which came first? (the chicken or the egg).
In my opinion, it's possible create good strategies in the three situations, and the first that came to my mind was using the second option (and so I choose this).
But option three looks more rational and I think will win.
A good Idea, could be to take an additional position, this could consist of a position in the opposite direction,
assuming you have a position at the start of the major trend then this would protect any gain and guard against a mini reversal come major one
I chose, Wait until small trend is the same as big trend
It makes sense in my book to follow the masses, more potential with the engine powering in the same direction as your position
