$SPY 260324 651 Call(SPY260324C651000.US)

Opening IV was higher than usual, intraday trading today continued to focus on the underlying stock,

$Direxion Daily TSLA Bull 2X Shares(TSLL.US)

was the first target I watched after the market opened today.

Due to my self-imposed rule of "observing and waiting for the first five minutes after the open,"

I didn't go long in time at 09:31.

Because the gain in the first five minutes exceeded $0.50,

I judged that the intraday high had already appeared,

and shifted my attention to other targets.

$Pro Shrt Vix Shrt Future(SVXY.US)

The trend was unclear in the first ten minutes after the open.

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

At 09:31, the candle was too long, likely to trade in a narrow range intraday,

not suitable for intraday trading.

$Alibaba(BABA.US)

09:39:42 $124.3600 => 09:41:59 $124.2400, SL $124.66, SHORT,

Due to fear of loss,

I didn't short in time at 09:35,

entered just before the trend reversal.

09:42:51 $124.5700 => 09:49:57 $123.9900, SL $124.36, LONG,

Opening a position on a long candle is a big taboo.

Not stopping loss in time led to an expanded loss.

09:50:08 $123.9900 => 09:52:30 $124.0880, SL $124.11, SHORT,

Shorting at the intraday low is also a big taboo.

09:53:02 $124.1000 => 10:02:06 $124.4700, SL $123.99, LONG,

Timely entry, but exited too early due to fear.

$Walmart(WMT.US)

10:07:39 $122.5800 => 10:09:54 $122.2918, SL $122.30, LONG,

For a continuous uptrend, one should enter on a pullback that doesn't break support.

10:11:59 $122.2700 => 11:14:30 $122.5247, SL $122.46, SHORT,

This level held on pullback, not suitable for shorting.

10:20:47 $122.8000 => 10:29:42 $122.8800, SL $122.50, LONG,

Exiting on the third bearish candle wasn't actually wrong.

11:37:57 $123.9400 => 11:51:02 $123.9320, SL $123.80, LONG,

FOMO buying at the intraday high is a big taboo.

Needs major improvement.

11:53:38 $123.7600 => 11:58:07 $123.4465, SL $123.92, SHORT,

Timely short when the high wasn't broken, betting on a decline.

Profit-taking was fairly timely.

Missed the decline starting at 12:23 because I was browsing Taobao and didn't short in time.

Summary:

1️⃣ Each intraday trade entry is a 50:50 probability.

When the subsequent movement differs from expectations, stop loss in time.

"Big wins, small losses" is the essence of intraday trading.

Try more, cut losses decisively when wrong,

is an effective method for profitability.

2️⃣ Prohibit doing things unrelated to trading during trading hours.
