What Is Time-Series Cross-Validation? Why Shouldn’t You Randomly Shuffle the Training and Test Sets for Cryptocurrency Predictions?

In quantitative cryptocurrency trading, machine learning models are often trained on historical data to predict future price movements. But if all the data is randomly shuffled and split into training and test sets, as in ordinary classification tasks, the chronological order may be disrupted, making the model’s evaluation results overly optimistic.

First, what is time-series cross-validation?

It is a method of organizing training and validation chronologically

What Is Signal Filtering? How Can It Reduce False Breakouts and Invalid Entries in Crypto Trading?

In crypto trading, many traders immediately chase a price breakout above resistance, but the price can quickly pull back, creating a false breakout. The purpose of signal filtering is to screen out low-quality opportunities using preset conditions after a trading signal appears, reducing unnecessary entries. However, more filtering conditions do not necessarily make a strategy more reliable.

Signal filtering means checking the trend, trading volume, volatility,

Soaring to $905! $SNDK surged overnight, leaving shorts completely stunned

This guy works at a security booth during the day and makes one trade at night—no stress about life.

SanDisk surged to $905 intraday last night, sparked by one key factor: November NAND contract prices jumped 50%, far exceeding market expectations. The third price hike this year has fully ignited the memory sector. Morgan Stanley swiftly rated SNDK “Overweight,” while demand for high-performance flash memory from AI servers continues to soar. Supply is expected to remain tight at least through 2028. This isn’t a rebo

What Is Multi-Timeframe Analysis? How Can You Combine Short and Long Timeframes to Avoid Making Poor Decisions Based on Local Price Action?

In crypto trading, BTC may be rising on the 5-minute chart while still being in a clear downtrend on the 4-hour chart. If traders only watch short timeframes, they can mistake a rebound for a trend reversal. Multi-timeframe analysis uses price structures across different timeframes to help traders understand the relationship between local fluctuations and the broader trend.

It means observing multiple timeframes

Behind Jensen Huang’s affair scandal: His $155.2 billion fortune could be split in a divorce, with his wife potentially receiving over $75 billion
After Huang admitted in a letter to employees that he had been “unfaithful” to his wife, the scandal not only sent Nvidia shares into turmoil but also put his $155.2 billion fortune at risk of a potential asset division.
Under California’s community property laws, assets accumulated during marriage are generally split 50:50. The key legal detail in this potential divorce case is that the couple married in the mid-1980s, while Nvidia was founded in 1

#Gate股票暢聊季 Nvidia loses $1.4 trillion in a month, but I cast my vote for Broadcom

After the US midterm elections in early November, the market began worrying about tighter data center permitting and regulation. The AI sector saw its most severe single-day sell-off of 2026: SOXX fell 12% in one day, Nvidia dropped more than 9%, and Broadcom fell more than 10%. The first rebound came on November 6 (AMD +11%, Intel +8%, Micron +5%). On November 9, the Philadelphia Semiconductor Index rose another 6.85%, with AMD up 13.26%, Broadcom up 8.78%, and Micron up 6.25%—but Nvidia bucked the trend, clos

Fueled by bets on a Fed rate hike, this short squeeze came out of nowhere!

You have to get back up where you fell, and the same goes for trading. The real problem is that SpaceX may never return to 120. Can I still wait for a chance to rebuild my position at 120? $SPCX

What Is Breakout Trading? How Can You Tell Whether to Enter or Wait for a Retest After the Price Breaks Through a Key Zone?

In cryptocurrency trading, when BTC breaks through a key resistance level, some traders chase the rally immediately, while others choose to wait for a retest. Both approaches have pros and cons. What really matters is not getting in before everyone else, but judging whether the breakout is sustainable and planning for risk in advance.

Breakout trading means looking for trading opportunities according to predetermined rules after the pri

Is the Nasdaq Rebound Just the Beginning? Whether Tech Stocks Can Hit New Highs Again Hinges on These Three Indicators

The Nasdaq has rebounded, tech stocks are active again, and the market is starting to discuss a familiar question: Has the next rally already begun?
To find the answer, watching index moves alone isn’t enough; at least three key indicators need to be monitored.
The first is capital spending by tech giants. Investments in AI data centers, servers, and chips are a key growth driver for the AI industry today. If major tech companies continue making sensible investments, demand a

#Gate股票畅聊季 AI Tech Stocks: The Exception and the Favorite—Why I’m Choosing AMD!

I’m bullish on AMD because it has had the strongest buying support in this rebound and has performance to back it up in its financial reports.
Data center business doubles: In the third quarter, the data center business grew about 2x, prompting Oppenheimer to upgrade its rating, with a price target of $600[6].
Lands a Google order: Google Cloud’s next-generation TPU 8tx uses AMD EPYC on the host side, giving AMD a visible and measurable share.
Nvidia leaves an opening: Capital is flowing out of Nvidia and into com

$WLD Longs have reached full TP1—the entire move played out as planned. All profits are locked in. Another successful trade has been closed.

Micron is around $734 now. It printed a large bullish candle yesterday and has bottomed.
You can go long at the current price, with a target near 855 and a stop-loss at 645.
Add to your position around 690 to guard against a second test of the lows.
Like Sandisk, nothing has really gone wrong with Micron itself; sentiment and valuation are what got hit. Bank of America maintained its Buy
rating yesterday. Micron also approved a $35.1B buyback in October, and it can start buying as early as December 9. These are all positives.
