$Tesla(TSLA.US)$NVIDIA(NVDA.US) Although I made money today, I think it was a failed trade.

I held onto NVIDIA's put all along, couldn't resist today, sold at a low point, and went to play Tesla's near-expiry options. Logically, this doesn't fit my own trading system. The result was volatility all day long, from a 30% loss, I luckily held on and turned a profit, then went on to play calls, again holding on to losses. Later, it rose to my ideal price, but because of greed over a few cents, I missed out on $2000.

After clearing out Tesla's calls before, I thought the earnings report risk was high and not suitable for trading. Looking at the indicators, NVIDIA might have a downtrend, so I took a gamble. But today, I still couldn't resist looking at Tesla.

First, I should firmly believe in my own judgment and not act recklessly. If I hadn't acted recklessly today, the profit would have been higher.

Second, for near-expiry options, hold at most 5 contracts. I got carried away again this time while playing.

Third, absolutely do not hold losing positions in near-expiry options, don't be greedy, exit when the target is reached.

Fourth, be able to endure loneliness.

The money I made in options was from medium-to-long-term options; the money I lost was from near-expiry options. Posting today to warn myself: must strictly execute within my own trading system.
