I notice that when there the price is going up so many people are joining the train and they also buy because the price is going up and they are going to make a profit, why people are not buying when it is down when the price will eventually go up and they can make a lot of profit.
There is this principle in trading and the principle is called "the trend is your friend" you hardly lose if you can trade along the trend line. When the market is at the top or down is always the most risky place to place a trade as it always go against most of the trading positions.
