This order was not closed in time, and the funding rate suddenly reversed, ultimately ending in a loss. Within the range of 682 to 711, a $12,000 trading position ultimately lost $30, with a loss ratio of approximately 0.25%. Market changes occurred much faster than expected, and changes in the rate direction are often more difficult to predict than price fluctuations. The clear lesson this time is— for short-term trading, monitoring the funding rate and risk management are just as important as technical analysis. Every trade is a learning opportunity; next time, let's do better.
