Yes trend is really our friend. But you need to be cautious at important levels and should wait for a break or bounce and then a retest. Haste makes waste.
I don't think if trend is always our friend, it's back to the trader himself who looked trend itself. Trend can be your friend to make profit if you could entry and exit in the right time. But trend can cause loss too if you don't know when is time for exit from trend. Sometime, trend will continue but in other time, it will move back and price moved in opposite direction. But it is easier to take advantage from trending condition than reversal condition in trading.
All traders have desire to be friend with the trend , but not few traders get difficulties in identtifying the true of current trends , some of time we are too late in entry of position in the end of trend and in another time we want take position as hurry in identifying the trend was reversed while in the fact not true
It is right. It's not easy to identify the real trending movement because price can move upward and downward with many things which can affect market's movement. Good traders are not only trading well in good condition but also making good decision in hard condition which can cause loss. Trend will be easier as our friend than we against the trend movement because trend will move longer than reversal movement.
Very right , forex market has shown unpredictable in many times , sometimes there are intervention of central bank in certain country and in other times there are condition that make certain country have unstable financial , so this can make the currency pairs move not certainly some times
