In the complex and ever-changing financial market, uncertainty is the norm. From the fluctuations of the macroeconomy to geopolitical tensions, and the rapid innovation in industry competition and technology, various factors intertwine to keep the market in a state of dynamic change. In the face of this situation, rather than falling into complaints about 'force majeure', it is better to invest energy into improving one's trading system, as this is the key to moving steadily through the bull and bear transitions in the market.

Contract Strategy. In position management, a single position model is adopted, with a leverage of 10 times and 1 layer of position. The advantage of this model lies in its ability to effectively control the risk exposure of a single contract, avoiding significant losses from a single trade that could affect the entire account.

When BTC is in the range of 83500 - 83800, choose to go long, setting the take profit level around 87500 and the stop loss level at 81262. This strategy is based on technical analysis, suggesting that the range of 83500 - 83800 may have strong support, making it likely to profit from price rebounds when going long. The level around 87500 serves as a previous resistance point where the price might encounter resistance and decline, hence it is set as the take profit level; 81262 is the lower edge of a key support level, and if it breaks down, it indicates a possible trend reversal, so it is set as the stop loss level.

The SOL trading strategy also follows technical analysis logic. Go long in the range of 132 - 133, with a take profit level of 138.32 and a stop loss level of 127.8. The range of 132 - 133 may represent a short-term bottom area, making it likely to seize the opportunity for price increases when going long. 138.32 is identified as a pressure level based on technical indicators and price trends, where profit can be realized upon reaching this price; 127.8 is an important support line, and if it breaks, a stop loss should be executed to prevent further losses.

The above strategies are only personal opinions and for reference only. If investors choose to follow these strategies, they must strictly adhere to the stop loss and take profit rules, accurately control the multiples and positions, and must not harbor a lucky mindset of holding onto losing trades, as they will bear the possible losses themselves. In future trading, continuously optimize the trading system to better cope with market uncertainties.
