What Are ROC Curves and AUC? How Can You Tell Whether a Price-Movement Prediction Model Can Truly Distinguish Outcomes?

In crypto quantitative trading, a model’s effectiveness cannot be judged by accuracy alone. Suppose BTC does not make a sharp move upward most of the time. A model that always predicts a decline might achieve seemingly good accuracy, yet fail to identify genuine opportunities to buy. ROC curves and AUC can help us evaluate a model’s ability to distinguish between different outcomes.

First, what is an ROC curve?

An ROC curve compares the true positive rate with the false po

What Is the F1 Score? How Can It Combine Precision and Recall to Evaluate a Trading Model?

In crypto quantitative trading, one model may issue very few bullish signals, resulting in high precision but missing many upward opportunities; another may identify most market rallies but generate many false signals. It is difficult to evaluate a model comprehensively by looking at just one metric. The F1 score is a way to jointly measure precision and recall.

First, what is the F1 score?

The F1 score is the harmonic mean of precision and recall, calculated as: F1 = 2 × precision × recall ÷ (precisi

Watched an entire round of ETH price action from to ~$EcoPro Materials, and finally couldn't resist making a move today😝
Just 5 hours ago, an address that had been dormant for a full year, 0xB47…0511e, suddenly spent $5.4 million to buy $ETH at an average price of 2113.46. Just yesterday, this address had received 5.4 million USDT specifically to buy the dip—and more interestingly, the funds had been quietly sitting in the wallet ever since they were withdrawn from various exchanges three years ago, when ETH was still hovering around $1,500.

At 21:30 Beijing time tonight, the U.S. Bureau of Labor Statistics will release October CPI inflation data. Because of the federal government shutdown in October 2025, which disrupted price collection that month, this report will not include year-over-year (12-month) changes in headline or core CPI. Markets will have to rely on month-over-month readings to assess the inflation trend.

Economists surveyed by Reuters unanimously expect headline CPI to rise 0.3% month over month and core CPI to rise 0.2%. This is the last CPI report before the Fed’s December policy meeting. Nonfarm payrolls previ

One blunt remark from the Fed chair sent all kinds of assets tumbling today.
Gold plunged 1.2%, silver slumped 2%, and Nasdaq futures weakened in response.
A few hours ago, Waller struck a hawkish tone in London, not only breaking the market’s ingrained expectations of easing but also laying out specific conditions for a rate hike:
Even if October’s CPI release tonight shows improvement, he still supports a 25-basis-point hike in December; and if core CPI rises 0.3% or more month over month, the Fed should consider going straight for a 50-basis-point hike, or risk undermining its credibility i

This U.S. stock market rebound is no ordinary rally! Is AI reigniting the market, or are institutions using the opportunity to “push prices up and sell”?

The U.S. stock market has been lively lately. Just a few days ago, the mood was bleak, but now tech stocks are rising and funds are flowing back in. Investors’ emotions have been on a roller coaster too: when prices fall, they question everything; when they rise, financial freedom feels just around the corner.
But what is really driving this rally? It’s worth taking a closer look.
If it’s just a technical recovery, the market’s rise is mainl

$GT ‌Looking at the broader structure, the market experienced a sharp initial drop from the 9.87 level down to a local bottom around 9.52, followed by a prolonged consolidation phase. Currently, the market structure is showing signs of a shift from a bearish slide to a range-bound accumulation, as price action is attempting to establish a higher low structure near the 9.74 support zone while compressing within the Bollinger Bands.

K Line Analysis: The price is currently trading at 9.79, hovering just above the middle Bollinger Band (MB: 9.72) and the short-term moving average (MA5: 44.20K),

AMEC has launched its Primo Matrix plasma wafer dicing equipment and completed its first delivery to a major domestic integrated circuit packaging customer. The equipment is designed for high precision, low damage, and narrow dicing streets, with a minimum street width of 5 micrometers to reduce wafer area loss.

When people talk about advanced packaging, they tend to focus on big concepts like stacking and interconnects. But what really drives yield is the painstaking work of narrowing wafer dicing streets to 5 micrometers. Every bit of material saved at the edges counts.

AI agents are no longer just a concept at product launches—they’re entering the congressional legislative process. S.5051 is called the AI AGENT Act. What’s most notable isn’t “tougher regulation,” but giving your personal agent an “ID card.” According to the bill’s text, agents on platforms with more than 50 million U.S. users could gain legal authority to act on users’ behalf, even in areas like personal finance. Imagine asking your agent to move 10% of your paycheck into a money market fund every month, automatically compare prices before renewing subscriptions, pay your credit card bill on

Some notable signals are starting to emerge on the $BTC side.
On the daily chart, the price continues to fall while RSI is making higher lows. In other words, even as the price hits new lows, selling momentum is not as strong. This is a strong positive divergence.
Yesterday's trading volume also gave me hope. Also, while Spot CVD is positive on most exchanges, Coinbase has not yet joined the buying in a meaningful way.
There is no confirmation of a reversal yet, but the picture is getting more interesting.
I would especially like to see buying pick up on Coinbase as well.
