$NVDA Call(NVDA260513C227500.US)

Today, I originally planned to trade $NVIDIA(NVDA.US) 0DTE options,

but the trend was unclear in the first five minutes after the open,

$NVDA Call(NVDA260513C225000.US)

09:52 $1.10 => 09:55 $1.50, SL$0.85, LONG,

I wanted to open a long position here,

but was afraid the long wick might lead to a pullback,

and didn't click to place the order in time,

10:49 $1.50 => 11:10 $2.90, SL$1.20, LONG,

$SPDR S&P 500(SPY.US) was approaching a breakout of the 09:22 resistance level at $739.040,

could try to open a long position,

$TSLA Call(TSLA260513C455000.US)

11:28 $1.17 => 11:33 $2.45, SL$0.85, LONG,

The pace was fast, and a moment of hesitation meant missing the opportunity;

Summary:

1️⃣ I made a mistake in the pre-market target selection phase today,

over-relying on AI, which led to errors in filling out the data table for "Previous H/L/C" and "PMH / PML",

and due to some fear of $Tesla(TSLA.US),

I first chose $NVIDIA(NVDA.US) as the intraday trading target;

2️⃣ At 09:40, I noticed $Alibaba(BABA.US) rising strongly,

by then it had already moved a lot, making chasing a long position risky,

waited for a short opportunity around 10:00,

and missed the big opportunity in $Tesla(TSLA.US).
