Volatility ranged from 0.70% at 09:42 to 1.29% at 13:56;

$SPY 260213 681 Call(SPY260213C681000.US)

opening IV was higher than usual,

correctly judged the opening volatile trend pre-market,

$Walmart(WMT.US)

09:41:45 $133.0800 => 09:43:50 $132.3050,

Thought to open a long position after the EMA Golden Cross,

but after buying, two consecutive bearish candles appeared,

should have entered when the bottom held for five minutes without breaking at 09:37,

and closed immediately if it broke down right after,

09:48:34 $132.8000 => 09:52:51 $132.6900,

Entering at a higher low was correct,

closed with a market order seeing it couldn't break through,

10:38:09 $133.4391 => 10:39:13 $133.2650,

Didn't break the EMA20 line, should have continued holding,

Should have opened a position at 10:06, but drew a continuation of the pre-market downtrend channel on the chart,

Two position openings, two losses, should have been more confident the third time,

The theory was correct, just encountered a low-probability event,

Thought it should adjust today, but it's still an uptrend,

just opened with a sell-off first, driving the price to a low,

11:17:45 $134.1790 => 11:36:25 $133.9300,

Opening long at the intraday high carries great risk,

An excellent trader should be like playing a shooter game,

anticipate the enemy's position in advance, get ready to shoot,

by the time the enemy appears, they've probably seen you too,

getting hit is inevitable,

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

10:52:00 $87.7480 => 10:59:06 $82.7800, LONG,

The entry point was correct,

just the trend didn't develop as expected, profit-taking was correct,

13:03:52 $83.0600 => 13:07:16 $83.1900, SHORT,

Shorting at the end of a trend is a big no-no, stopped loss in time,

13.09:26 $83.2400 => 13:22:33 $83.4725, LONG,

The trend isn't very strong, not suitable to trade this ticker today,

Summary:

1️⃣ Open the 1-minute chart of the ticker you plan to trade that day on your computer;

2️⃣ Fridays before long weekends are very difficult to trade, similar to around Christmas, basically quant-driven;

3️⃣ Next week tentatively only trade $Walmart(WMT.US), usually has a $3 intraday amplitude;

4️⃣ For 0DTE options, focus on Paper Trading first, no live trading,

Currently $S&P 500(.SPX.US) can't break through around 7000 points,

5️⃣ When both the 1-minute and 5-minute charts are trending up/down simultaneously, it's a relatively safe entry point,

6️⃣ Market closed next Monday, conduct a more detailed review of $Walmart(WMT.US).
