What Are Precision and Recall? Why Can't Trading Models Simply Aim for More Bullish Signals?
In crypto quantitative trading, a model may generate a large number of bullish signals every day, but more signals do not mean more profit opportunities. If a model frequently mistakes a falling market for a rising one, traders may repeatedly hit their stop-losses. Precision and recall measure a model’s ability to identify bullish opportunities from different perspectives.
First, what is precision?
Precision is the proportion of samples actually followed by a price rise among all those the model classi

What Are ROC Curves and AUC? How Can You Tell Whether a Price-Movement Prediction Model Truly Has Discriminative Power?
In crypto quantitative trading, a model’s effectiveness cannot be judged by accuracy alone. Suppose BTC spends most of its time without a sharp rise. A model that always predicts a decline could still achieve seemingly decent accuracy, yet fail to identify genuine opportunities to profit from a rise. 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 wit

What Is Feature Standardization? Why Can Data with Different Units Affect Machine Learning Trading Models?
In crypto quantitative trading, a model may use features such as price returns, trading volume, volatility, and funding rates. However, these data can have very different value ranges. Without proper processing, some algorithms may be affected by feature scales and struggle to learn effective patterns consistently.
First, what is feature standardization?
Feature standardization converts data with different scales into more comparable numerical ranges. A common method is Z-score standardiz

The Fed left interest rates unchanged, but my read of the press conference that followed was hawkish. The press conference itself was not as hawkish as initially feared. To be precise, the Fed paused rate hikes but did not signal a clear shift toward easing.
First, its descriptions of the economy and inflation were hawkish. The Fed described economic activity as expanding at a solid pace while explicitly stating that inflation remains elevated. This essentially means there is not yet sufficient reason to clearly shift toward easing.
The decision passed 10-2, with two committee members favoring

$NEAR SHORT SETUP — 4.20 NEXT?
$NEAR is facing heavy selling pressure after a sharp rejection from 4.81. The 1H chart shows a strong bearish breakdown, with price losing the 4.60 and 4.47 support levels. A weak recovery could offer another short opportunity.
Entry: 4.44–4.48
SL: 4.56
TP1: 4.38
TP2: 4.30
TP3: 4.20
Extended Target: 4.10
A confirmed break below 4.38 would strengthen the bearish setup, while a recovery above 4.56 would weaken the short outlook.

Once the mainnet launches, does it immediately get listed on exchanges?
Whenever people in the group see “mainnet launch,” someone chimes in: “Does that mean it can be traded on exchanges right away?”
There are actually a few steps in between.
A mainnet launch mainly means the blockchain is officially up and running; an exchange listing means the platform supports trading that asset. It’s like a factory starting production—it doesn’t mean every shopping mall will stock its products that same day.
An exchange still needs to decide whether to support the asset, complete its assessment and techni

Over the past few months, AI API prices have kept falling, while subscriptions still cost $20 a month. I checked the official pricing pages of two providers:
- For Anthropic’s flagship Fable 5.1, cached reads dropped from $1 per million tokens for the previous generation to $0.25; the planned September increase for Sonnet 5 to the 3/15 price was canceled
- OpenAI’s current flagship gpt-6.1-sol costs $2 for input and $10 for output
- Claude Pro is still $20 a month, while Max starts at $100, but Max now includes $100 in API credits each month
API and subscriptions are billed separately. The API

The Fed announced last night that it would keep interest rates unchanged. On the surface, it looks like a “pause,” but take a closer look at the details: a 10:2 vote, with two members calling for a 25-basis-point hike, and the probability of a December hike surging above 78%. What does that tell us? A hawkish pause—once good news is fully priced in, it becomes bad news.‌‌

The market action is more honest than the news. $ETH On the 2H chart, price spiked to 2387 and then quickly closed with a bearish candle; MACD momentum faded. The short order I placed at 2372 before bed was a bet on long

#谷歌云增长103%股价却跌近10% #每周来晒 Google's sharp after-hours drop this time shows that investors now demand stronger evidence that the “AI story” can continue to deliver. In the short term, the market is focused more on earnings and cash flow, while betting on AI growth over the long term.
Why cloud business surged while the stock fell
The cloud business is indeed very strong: Google Cloud revenue grew 103% year over year to $30.709 billion; operating profit was $11.121 billion, and its margin rose to 36.2%. AI infrastructure, solutions, and TPU sales are all driving growth.

I thought I’d get filled at 78500—only after reviewing this month’s daily candles did I realize the low was just 79220. It never touched 78500 once.
The group of people I’m watching hasn’t budged these past two days either: going long near 78500, short near 82500. Place orders on both sides first, then just wait.
82500 is more worth watching: yesterday’s post had 82300, and today this person moved it up 200 points. The price was above that level on 22 days this month. After touching 84377 on 10-22, the high over the past 7 days was only 81823.
So “patience” isn’t just empty reassurance. Both l

Same gold, different prices.
On October 27, @Tether’s XAUT traded at a 0.16% discount to spot gold, while @Paxos’ PAXG traded at a 0.05% premium.
That’s a 0.21 percentage-point gap between two tokens backed by the same commodity.
Their market values also differ considerably:
→ XAUT: $2.97B
→ PAXG: $1.77B
PAXG offers monthly reserve attestations and direct redemption fees starting at 0.125%. XAUT provides quarterly attestations and charges 0.25% for direct redemption.
But for retail holders who aren’t redeeming physical bullion, execution price and secondary-market liquidity could outweigh thos

#FedKeepsRatesSteady | What Does It Mean for Crypto?
The Federal Reserve has kept interest rates unchanged at 3.75%–4.00%, emphasizing that inflation remains elevated and more economic data is needed before making further policy decisions. However, two officials preferred a rate hike, highlighting the uncertainty surrounding the Fed’s next move.
For the crypto market, stable rates do not automatically mean a bullish trend. Bitcoin and altcoins will remain sensitive to inflation data, the US dollar, Treasury yields, and expectations for future monetary policy.

Mr. Daxiao is a deeply compassionate person. He saw through the true nature of the stock market long ago, and he also shared the solution with ordinary people long ago: “Be a good person, buy good stocks, and reap good rewards.”
For most people, this is the best solution, because the stock market is a zero-sum game—or even a negative-sum game. The greedier you are, the deeper you get in. The less you can bear, the harder it is to get out.
But human nature is what it is, and the stock market is precisely where human nature plays out. He saw through all of this long ago, too.
And yet this old ma
