Could anyone tell – how to identify the trend direction at its very beginning, not at the end? or it is impossible?
How can anyone identify something that can only exist in hindsight?
Seriously, when I read the article by Michael Harris in Fidelity Active Trader website many things cleared up in my mind. I think it is a masterpiece. The link is:

Here is an excerpt about trends:
"The elusive trend
A price trend is probably one of the most elusive concepts in trading because a trend can only be identified after a significant portion of it has already formed. More importantly, every price level in a trend is a potential reversal point, making it impossible to know if prices will trend up or down at any given time.
Also, any indication of a longer-term directional bias cannot be determined from analyzing price data alone. This is because buyers and sellers match exactly at every price point; the only thing that differs is "price concession." When buyers concede to higher offers, prices move up; the opposite occurs when sellers concede to lower bids. However, there is no way of knowing traders' longer-term motives. Among other factors, short-selling and bluffing blur the market picture, resulting in "noisy" market conditions. Traders who understand how noise affects technical indicators, especially trend-following ones, know these tools have little value as the basis of trend-trading systems with a chance to be consistently profitable over time.
But in addition to the theoretical problems that explain why commonly used technical trend-following methods tend to fail, there are also some disturbing realities every trader becomes aware of at some point.
Sudden trend reversals can cause devastating reductions of open position profit, or even turn a profitable trade into a loser. Understandably, these events can adversely impact a trader's psyche, especially a trader with limited experience. Even veteran traders are not immune to the stress of holding open positions for extended periods of time and being subject to high volatility and adverse gap openings.
At the other end of the spectrum, many short-term traders become addicted to pulling the trigger and pocketing small profits after minimal favorable price moves. When it comes to trend trading, though, patience is a virtue. "
