High winning rate, ultra short term trading is a trade that breaks through the price structure. After the breakthrough signal is issued, entering the battle and having a very high winning rate. 3. With a low profit to loss ratio, the market situation is dangerous and complex, and continues to be in a chaotic state. Therefore, it is best to lock in profits and leave in a timely manner. This also has a natural disadvantage of being unable to wait patiently for the development of the market. However, ensuring the safety of funds and controlling withdrawals are the primary tasks of a professional trader. So even if you sometimes miss out on huge profits, you can only express regret about it. In the treacherous trading jungle, catching and running is the safest way, you don't know if there are still predators behind you. What is speculation? Most people have a natural bias towards speculation, believing that it is an illegitimate industry that links speculation with speculative activities. In fact, the definition of speculation in trading is: traders find a suitable trading strategy in the market, conduct backtesting and actual testing, discover a suitable profit loss ratio and win rate, and have an overall expectation greater than 1. After multiple consecutive trades, profits and losses offset each other, ultimately achieving a positive growth in overall position. The key during this period is: 1. Able to conduct multiple consecutive transactions (multiple experiments) 2. The entry and exit conditions for each transaction are the same (controlling for variables) 3. Finally, under the power of mathematical statistics, achieve a trading strategy with positive expectations. Therefore, it can be said that ultra short term trading is to find one or more trading strategies in the market, enter immediately after the market signal is issued, and exit immediately after the end signal is issued. Even if there may be losses, the overall expectation is greater than 1, so traders can achieve stable growth of funds in long-term trading. And this also requires traders to maintain consistency in trading, consistently following the set trading strategy to avoid differences in trading results due to changes in conditions.
