The core of the crypto world Contract Trading lies in Risk Management and trend analysis. Firstly, strict Position control is the foundation of survival, with a single Position recommended not to exceed 2%-5% of the principal, and the total leverage ratio controlled within 10 times to avoid excessive speculation. Secondly, it is necessary to establish a clear trading system, combining technical indicators (such as EMA, Bollinger Bands) with volume-price relationships to determine the trend direction, trading with the trend is better than counter-trend operations. Thirdly, strictly implement stop loss and take profit, use dynamic tracking of stop loss to protect profits, refuse to hold a losing position when losing, and avoid emotional decisions. Fourthly, follow the market Liquidity and the distribution of liquidation lines, be vigilant of Long Wick Candle markets. Finally, the essence of contracts is a Zero-sum Game, and one must maintain a clear understanding: over 80% of traders lose money, while excess profits come from forward-looking judgments on market sentiment and counter-human operations in extreme Fluctuations. Avoid treating contracts as a tool for getting rich quickly; long-term survival is more important than short-term windfall gains.
