Event Contracts: Nothing is difficult to understand

A misstep, whether at the peak or the bottom

As long as you persist in doubling your bets, you can achieve stable profits

Doubling formula: 5, 8, 18, 40, 100

As long as you have a basic understanding of the market and can identify support and resistance levels

Patiently wait for the highest point to sell and the lowest point to buy

A misstep in one market can lead to a second round of doubling

Every time you misstep in the market, it will make your bottom or peak buying safer. Some may ask why you always win and never lose; that's because you can only issue 4 charts at a time, and to follow the trades, you need to prepare a threshold of 50U.
