Why do some people think that contracts are gambling? Because they completely ignore K-line analysis of price trends and rely solely on their feelings about whether prices will rise or fall. Trading based on feelings is even worse than tossing a coin, as tossing a coin gives a 50% chance of being right, while relying on feelings has a success rate that is definitely below 50%, because feelings are often wrong. In fact, price trends can be predicted based on previous prices. Making money with contracts is really easy#合约交易
