Technical tools such as technical charts, shapes and indicators are all windows to observe the psychology of the market public, and various technical tools tell the truth of the market from different perspectives. However, a single technical index presents investors with one side of the market, not a complete overall image. Therefore, only relying on a single technical tool to spy on the public psychology will inevitably lead to a misunderstanding.

Different indicators reflect different aspects of public psychological behavior. In order to see the essence of the market more clearly, we need to use these tools together Excellent systems often use a variety of reasonably matched tools, so that their negative effects cancel each other out, while their advantages are not affected, and they can become weapons to arm themselves.

Second, we should flexibly choose technical tools to play a role according to the opportunity.

Furthermore, even the combination of indicators depends on what stage the market is in. Only when the market enters some specific stages can they show powerful effects. If the same technical tools are used indiscriminately at every stage of market operation, the effect will be greatly reduced.

Some investors like to use short-term technical signals to decide short-term operations. The main short-term transactions are mostly anti-news and anti-technology operations. But correspondingly, ordinary investors follow the "should" guidance of news, or follow the buying and selling signals sent by ultra-short-term technology to conduct "logical" transactions. The results are often "diametrically opposed" and "very different". In this case, the effectiveness of most technical indicators will become limited.
