“There is only one side of the market and it is not the bull side or the bear side, but the right side.” — Jesse Livermore
The only way to profit from stock/currency, even if the value of that stock/currency is really high, it is by buying and selling at the right time. Every trader has a different motivation of buying or selling. One of the most logical reason to buy a stock/currency is because you think that will help you make money. On the other hand there are plenty of reasons why you sell a stock/currency. It can be because you need cash, you think that the price of that particular stock/currency will go down, you want to invest in something better, some news you heard about etc. Everyone who takes part in the market has one single motivation: to make money, whether that is a big investor, an experienced trader, a day trader, growth investor, trend followers, it’s simple, they want to make money.
