$SPY 260227 683 Call(SPY260227C683000.US)

The oscillation range was very small in the first ten minutes after opening,

Unable to determine the intraday trend,

$SPY 260227 684 Put(SPY260227P684000.US)

12:11 $0.75 => 12:23 $1.80, SL $0.55,

Unable to break the intraday high,

A long bearish candlestick appeared, could try a short position,

$Walmart(WMT.US)

09:53:29 $126.2500 => 09:55:52 $126.2077, SL $126.48, SHORT,

I wanted to short when it couldn't break the intraday high as early as 09:45,

But I still waited until the downtrend was established before opening the position,

Anticipating a possible drop to the gap position at $124.600 where the pre-market uptrend started,

It didn't actually happen, fortunately took profits in time,

The shortcoming was not opening a long position in time,

$GraniteShares 2x Long NVDA Daily ETF(NVDL.US)

10:17:43 $80.1300 => 10:19:12 $79.9900, SL $80.30, SHORT,

Chasing the short after the long bearish candlestick at 10:16 was actually a bit late,

The best entry point was at 10:14,

10:48 $80.750 double top was also a good entry point,

$Pro Shrt Vix Shrt Future(SVXY.US)

12:23:11 $52.2300 => 12:23:47 $52.3050, SL $52.40, SHORT,

Today's trend movement was larger than that of $SPDR S&P 500(SPY.US),

Still opened a position at the late stage of the trend, the best point was at 12:11,

Summary:

1️⃣ Today is Friday, also the last trading day of February,

The market experienced $NVIDIA(NVDA.US)'s earnings day,

Should have gradually calmed down,

There seems to be new news about US/Iran,

The market is waiting for possible new developments over the weekend,

Trading volume was not high after the midday break;

2️⃣ Saw someone who got a margin call again today, I remembered a few sayings:

"No one can be absolutely right, hold when you're right, cut losses in time when you're wrong!",

"No one can buy at the lowest and sell at the highest, we just stand on the side of high probability!",

"Most of the time in intraday trading should be holding stocks/options, not cash. The purpose of intraday trading is to grow small capital, through the leverage effect of margin accounts/options, allowing capable people who lack funds to quickly accumulate initial investment capital!".
