Who understands it? The thing about contracts is that it's all about the thrill; it can come quickly and go even faster. It can make you rich overnight, but it can also blow you down to drop to zero in a matter of minutes.

In simple terms, a contract is an amplified version of spot trading, money comes in quickly, but losses can be even faster. If you want to understand it well, you must first grasp the rules.
Don't ignore funding fees. Positive fees mean that longs are giving shorts a red envelope; at this time, don't stubbornly chase high prices. Negative fees mean that shorts are giving longs money, which often indicates that the market is likely to drop further.
Leverage should not be used recklessly; it's like a magnifying glass. When you earn, it doubles your gains, but when you lose, it also doubles your pain. Newcomers should stick to 3 to 5 times, that's enough. More than 10 times is for professional players, not a place for gambling luck.
How to play, I summarize it into four steps.
First, look at the big picture, don't get overly excited by the one-minute candlestick chart; at least start with the daily chart. The moving averages and MACD can tell you where the trend is.
Secondly, find the entry point. A pullback to the middle band of the Bollinger Bands on the four-hour level, with the RSI turning upwards, is a reliable position. If the trading volume suddenly increases and breaks the pattern, the signal becomes even more stable.
Third, set a stop-loss in advance, don't fantasize; withdraw immediately when it hits the stop-loss point, hesitation will lead to liquidation.
Fourth, take profits in a timely manner. Cash out as soon as you make a profit, even if it’s just 10%. Remember, there will always be the next wave in the market; greed will only cause you to give back your profits.
To be honest, don't have too much position; use at most 30% of your capital on one variety.
Contracts are not about who earns faster, but about who can survive longer. The market will always have fluctuations, opportunities will come and go, don't rush for quick gains and end up losing your principal first.
