Why do I place limit orders much lower than the current price levels?

Caution is an important trait of any trader. Only cold calculation.

Possible reasons for a fall that I highlight:

1. The market has been soaring for almost a month, there has been no normal correction.

2. The U.S. Federal Reserve meeting on July 30 and the announcement of the rate.

3. Donald Trump's tariff policy takes effect on August 1.
