March Earnings Record

March was a month of extreme volatility. I tried to summarize my experience today, but repeatedly told myself that it was my luck redeeming me.
In mid-March, the account hit a new high, and the return on holding SanDisk had already reached 1000%. In the latter half of the month, a black swan event combined with poor operations nearly caused me to underperform the S&P, with a monthly decline of 10%.
But in the end, luck turned the tide. Continuously adding positions during this wave of gains resulted in profits I shouldn't have gotten.

This is the first time I've encountered a black swan since entering the US stock market.

I've been thinking about a question: Under a black swan, should one still stick to their own discipline and trading system?
The answer I've come up with now is yes, but the conditions need to be relaxed. For example, originally, if the price fell below the 5/10-day moving average for 2-3 days and couldn't recover, it was a sell signal. But under black swan conditions, extend the 2-3 days to 3-5 days, because black swans easily lead to overbought/oversold conditions and amplify market sentiment.
