What is the essence of trading strategy? It is well known that excellent traders never trade based on feelings, but only place orders according to trading strategies. A so-called trading strategy is essentially a combination of market advantages. In the market, there are countless conditions that can represent a buyer or seller's certain market advantage, such as the highs and lows of market fluctuations, the position and direction of the 20-day moving average, the size of trading volume, and so on. To achieve a higher win rate in trading, these market advantage factors need to be integrated and stacked together. One should only enter the market when one side, either the buyers or sellers, has sufficient advantages; this is the trading strategy. At the same time, having more stacked advantage conditions in a trading strategy is not necessarily better. The more conditions stacked in the strategy, the harder it becomes for the market to meet the trading strategy, leading to a sharp decrease in trading opportunities. If one wants to achieve a high win rate while ensuring a certain number of trading opportunities, it is necessary for the advantage conditions within the trading strategy to work together for efficient stacking. This process is akin to cooking; a good dish is not created by mindlessly stacking countless seasonings but by the interaction of a limited number of seasonings to enhance flavor. A good trading strategy is similar. For a professional trader, it can be said that the trading strategy is their core competitiveness. It takes a lot of time to develop a trading strategy from scratch; it is a process of continuous validation, improvement, validation, and improvement, usually taking about a year to complete. Therefore, for trading novices, the best way to start is not to create a strategy from scratch, but to learn from existing strategies and then refine them to create their own. Of course, digesting and absorbing trading strategies also requires a process, but this process is far more efficient and quicker than developing from scratch. In the process of learning trading, the most taboo thing is to trade based on feelings. It can be said that in the trading process, 'feelings' are the least reliable aspect of all your analyses. Trading without 'feelings,' and learning to rely on trading strategies, is the first step to becoming a successful trader.
