In the financial markets, successful trading is not about frequent operations, but about knowing when to sit on the sidelines. This article shares the journey of a trader from losses to profits, as well as the five important trading principles he has summarized.

First, the author reflects on the mistakes he made when he first entered the industry. Like many newcomers, he was obsessed with various trading strategies, frequently looking for entry signals, which resulted in heavy losses. After a year of reflection and learning, he realized that the essence of trading lies in knowing "what not to do," rather than blindly executing actions.

Next, the author elaborates on the five core principles of "not opening a position":

1. Focus on familiar market areas to reduce unnecessary trading frequency. Stick to a proven trading system and do not change strategies easily.

2. Emphasize risk management. Truly successful traders prioritize risk control as their primary task, as the market is ever-changing, and it is difficult to achieve long-term profitability without proper risk management.

3. Only enter the market at key positions or when clear signals appear. Wait for the trend to pull back at support or resistance levels, and confirm the breakout before taking action. Stay patient when there are no clear signals.

4. Determine a clear stop-loss position before opening a position. If you cannot find a suitable stop-loss point or the stop-loss space is too large, it is better to give up that trading opportunity. Controlling the extent of losses is key to profitability.

5. Avoid ambiguous market conditions. Experts decisively abandon opportunities that are "optional," while novices often rush to find entry points. Trading should be based on certainty.

For beginners, the author suggests either patiently building their own stable trading system or learning from experienced traders. Trying to gain experience through long-term exploration and significant losses is an extremely painful and high-risk path.

In summary, successful trading requires adhering to discipline and diligently following established trading rules. Only in this way can one make steady progress in a complex and ever-changing market and achieve long-term stable profits.
