Unless I've misunderstood what you mean by trading with a "strong trend", then this would mean accepting that:
(a) you will always miss out on a big part of the move (the formative stage before it developed into a strong trend)
(b) you may be entering just as the trend is about to end, and possibly even reverse
(c) you will only ever be able to capture a portion of the entire move
(d) you will have to sit patiently, doing nothing, maybe for quite a long time, until a strong trend occurs
I doubt this approach would appeal to many (retail) traders.
Point (d) also incurrs an "opportunity cost". All of the time your chosen instrument is not strongly trending, you won't be making any money.
Obviously, you could use leverage to try and increase the overall return, and offset some of the opportunity cost, but there is another way.
