What is the key factor that determines whether trading can ultimately make money? 90% of traders have not understood this question! The key factor that determines whether trading can ultimately make money is 'strictly executing one's own trading system.' In the trading market, many people clearly have a stable and profitable trading system, but why are they still unable to achieve consistent profits? The main reason is 'not strictly executing one's own trading system.' How can one strictly execute their own trading system? 1. 100% trust in one's own trading system 1) The trading system must be tested and verified hundreds or thousands of times by oneself to finally confirm its ability to generate positive and stable profits. 2) Believe that as long as you strictly follow your own trading system, you can make money. 2. After developing trust in your own trading system, execute it 100% as per the trading system 1) When a profitable opportunity that meets the trading system appears in the market, open a position without hesitation, and do not get entangled. 2) Set stop-loss levels with peace of mind. 3) After opening a position and setting the stop-loss and exit time, it is best not to stare at the market (even when watching the market, there should be no emotional fluctuations in response to 'price fluctuations'). 4) Only check the market at the set exit time; at that point, profit can be harvested. Whether experiencing a roller coaster ride, being stopped out, or having a significant movement in the direction of the entry after being stopped out, there should be no emotional fluctuations. Accept all possible trading results calmly, let everything take its course, and regardless of profit or loss, keep your mind as calm as still water!
