A friend sends you a screenshot of a strategy: “Using this method over the past year, the returns look great!” You look closely and realize it says “backtest.”
A backtest applies a set of trading rules to past market data to see what would have happened if you had followed them at the time. It can help test an idea, but it’s not the same as realized returns from live trading.
It’s a bit like taking exams from previous years. Doing well is certainly useful as a reference, but if you keep revising your approach by looking at the answers, getting a high score in the end doesn’t mean you’ll do jus

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

2026.10.29 BTC/ETH/XAU/SNDK Analysis
The market saw $356 million in liquidations over the past 24 hours, with 81,823 traders wiped out. Interest rate night, meat grinder night!
BTC
Support: 75475-78425
Resistance: 85150-87500
Key level: 79000-79500 range. Compared with the multiple tests of 79000-79500 this week, the volume behind the overnight drop wasn't significant. If this key range holds, the next rebound could potentially reach a new high. So over the next two days, focus on whether this range breaks down on increased volume or stabilizes with a reversal in volume.
ETH
Support: 2215/2150

There is something I have noticed about some Igbo politicians, and it is the ease with which they throw their own brothers under the bus just to please their political masters.
When I look at what Papa Ozona and Umahi are doing, someone might think they are acting this way because they have presidential ambitions. But honestly, I don't think that is the main reason. To me, it looks more like an attempt to gain Tinubu's attention and prove their loyalty to him.
Now, look at Governor Hope Uzodimma. In all honesty, I have never been his fan, but I have watched him closely since 2023, and I cannot

Is this rally in $INIT the start of a trend or a short-term spike? From a technical perspective, it looks more like a corrective rebound driven by an extremely negative funding rate after bearish momentum faded, rather than a broad shift to bullish.
In terms of moving averages, MA5=0.221654 has crossed above MA20=0.214094, indicating short-term strength, but the current price of 0.22062 is slightly below MA5, suggesting a modest pullback after the surge. The MACD histogram remains at -0.000773, still in bearish territory but narrowing, meaning momentum is recovering rather than confirming a r

Seeing fees flow into a liquidity pool every day feels pretty good. But when you do the math, you realize that if you hadn’t put those coins in and had just held them, you might have more now.
This involves what people often call “impermanent loss.”
Take a common two-token automated market maker pool as an example. When the relative prices of the two tokens change, trading and arbitrage cause the proportions of assets in the pool to shift. What you withdraw may not be the same quantities of each token you put in.
Think of it as an automated exchange counter: when one type of asset gets more ex

The Fed held steady, but the vote was 10 to 2, with two votes outright calling for a rate hike😂
Forget about a rate cut in December; not hiking would be a New Year's miracle

After seeing a lead trader post their returns, you check your own copy-trading account: You’re following the same person, so why are your profits so different?
Copy trading replicates trading actions, not the other person’s profit figures.
It’s like two people shopping from the same list: if they arrive at different times, pay different prices, or buy different quantities, they’ll spend different amounts in the end.
Here’s an example, ignoring leverage and fees: The other trader buys at 100, while your actual execution price is 102. You both sell at 105. Even though you’re trading in the same
