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

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

09:45:01 $11.6200 => 09:46:24 $11.6800,SL$11.70,SHORT,

It was not the best target for intraday trading,

unlike $Alibaba(BABA.US) and $Walmart(WMT.US) which had strong trend continuity,

10:06:09 $11.5807 => 10:11:19 $11.5997,SL$11.63,SHORT,

Hesitated to open a position, went short at the end of a trend,

but stopped loss in time, this level became intraday support,

10:11:38 $11.6076 => 10:15:49 $11.6550,SL$11.55,LONG,

Opened long position timely, upward movement was not smooth, took profits too early,

11:20:54 $11.7200=> 11:24:21 $11.7489,SL$11.75,SHORT,

Continued the previous uptrend, set a new intraday high,

11:30:16 $11.6700 => 11:34:08 $11.6450,SL$11.72,SHORT,

Downward movement was not smooth, took profits too early,

Missed the shorting opportunity at 10:42 when the rebound failed to break through,

12:41:42 $12.1093 => 12:44:14 $,12.0600,SL$12.03,LONG,

Saw the breakout at 12:37, but was watching short videos at that time,

Did not see the news "Iranian President Pezeshkian: We are ready to end the war, but hope to obtain guarantees."

Missed it and chased to open a long position, resulting in a small loss,

12:48:08 $11.9907 => 12:49:17 $11.9880,SL$12.05,SHORT,

Did not short at the high point in time, chased to open at the low point, sold at the end of the trend,

13:29:27 $12.0307 => 13:30:15 $12.0500,SL$12.08,SHORT,

At 13:20, seeing it not making new highs, prepared to short,

Due to fear of loss, did not open a position in time,

Sold at the end of the trend, stopped loss and exited,

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

10:53:53 $69.0512 => 10:58:31 $68.9488,SL$69.15,SHORT,

Sold too late, only made minimal profit,

Summary:

1️⃣ Today's $Direxion Daily TSLA Bull 2X Shares(TSLL.US) was not a high-quality target for intraday trading,

Before the positive war news at 12:36, it only oscillated narrowly within a $0.20 range;

2️⃣ Missed the shorting opportunity on $Walmart(WMT.US) at 09:48 and the long opportunity at 11:00 due to fear of loss;

3️⃣ Obsessing over one stock is also not good. If the day's trend is not favorable,

it often wastes a whole day of trading time.
