When a trader is trying to find a trend, he should be looking at the timeframe he is currently trading and the next higher timeframe (for example H1 and H4), but the main focus should be put on current timeframe.
A trend is a continuous move in the market either up or down. During a trend, the market will make small corrections and pullbacks along the way, giving you a zig zag look, but overall, the market is moving in one paarticular direction. Until the moment of trend reversal.
