Trading is the buying or selling of a particular asset based upon the traders view of future movements in the price. The trader is looking to make a profit by correctly predicting these movements.
A key aspect of trading in markets like forex and commodities is the ability to profit whether the price goes up (HIGH) or down (LOW) in what time frame.
We have further information on trading on the Zentrader Overview page. The free trading platform demo is also a great place for new traders to start.
