What Is Overfitting? Why Can More Finely Tuned Parameters Make a Strategy More Fragile?
In cryptocurrency trading, some strategies show increasingly high historical returns and increasingly attractive backtest curves after repeated parameter adjustments. However, once they enter live markets, their performance can quickly deteriorate. A common reason behind this is overfitting.
First, what is overfitting?
Overfitting occurs when a strategy adapts too closely to specific fluctuations and chance patterns in historical data, leading it to perform well in the past but lack the ability to adapt to

What Is the Sharpe Ratio? How Can You Measure Whether a Trading Strategy’s Returns Are Worth the Risk?
In cryptocurrency trading, a high return does not necessarily mean a strategy is good. If a strategy can generate high returns but comes with sharp volatility and substantial drawdowns, we need to assess whether those returns are worth the corresponding risk. The Sharpe ratio is one tool that can help answer this question.
First, what is the Sharpe ratio?
The Sharpe ratio measures the excess return earned by a portfolio or trading strategy per unit of volatility risk. Generally, the higher th

11.5 Midday Analysis$BTC
After a sharp rally yesterday, Bitcoin has now entered a consolidation and recovery phase. The lower Bollinger Band is providing support, bearish MACD momentum has eased somewhat, and the KDJ has turned upward from low levels. The broader weak trend is gradually improving, and the current pullback can be viewed as a healthy confirmation during the bottoming process. The room for an upside rebound deserves close attention.
After pulling back to its low on the 4-hour chart, the price stabilized and moved higher. The Bollinger Band channel is gradually rising, MACD volum

U.S. stocks rallied last night, but semiconductors were singled out and hammered😮‍💨
The S&P 500 rose 1.6%, while Micron $MU , SanDisk $SNDK , and Marvell all fell more than 7%, and Nvidia wasn't spared either
I think this sell-off needs to be viewed in the context of the U.S. midterm elections:
The Democrats won the Texas gubernatorial election, and the incoming governor had previously explicitly called for a pause on approvals for new data centers until stricter regulatory rules are introduced
This is a major shift:

The Midterm Shockwave: How a Divided Government Just Broke the AI Supercycle
For months, Wall Street has been held hostage by a singular, anxiety-inducing question: When will the AI bubble pop?
On Wednesday, the U.S. midterm results finally became clear, delivering a decisive shock to the system: Democrats swept both chambers of Congress.
This created a divided-government setup in Washington—and the market’s reaction was immediate, brutal, and highly selective. The bubble didn’t explode in a fiery crash of bankruptcies; instead, the money simply walked away from the

What Is the Difference Between Isolated and Cross Margin? Which Margin Mode Is Better for Managing Risk?
In crypto futures trading, margin mode, in addition to leverage, also affects account risk. Isolated and cross margin are two common options. The key difference is whether other funds in the account help absorb risk when a position incurs losses.
First, what is isolated margin?
Isolated margin allocates separate margin to a specific position. Typically, losses on that position are primarily covered by the margin assigned to it, and other funds in the account are not automatically used to ma

SNDK fell again last night, closing at 1037 after plunging 9% at one point intraday.
Before earnings, it was still at 1405. In less than a week, it fell 26%.
When it dropped to 1150 last Friday, Dachao said not to rush into buying the dip and to wait for it to hold steady for a few days. But it failed to hold 1150, then failed to hold 1093, and kept plunging. Those who didn't rush to buy the dip dodged another bullet.
This isn't just about SanDisk. Micron and Western Digital also fell 7%, with the entire storage sector being dumped.
One factor is the same old issue: storage price increases are

Trump’s midterm election loss has instead sent markets higher.
U.S. stocks rebounded, A-shares rose, gold strengthened, and oil prices plunged.
The market is finally starting to reprice.
Democrats taking both chambers of Congress means Trump will face more checks on tariffs, fiscal policy, and foreign policy.

Previously, high oil prices drove up inflation and dampened expectations for rate cuts.
Now that Republicans have lost, the market is betting the U.S. may move faster to de-escalate the conflict.

What Is Trade Expectancy? Why Does It Reflect a Strategy’s Long-Term Profitability Better Than Win Rate Alone?
In cryptocurrency trading, a high win rate does not necessarily mean you’ll make money, and a low win rate does not necessarily mean you’ll lose money. What really matters is how much profit or loss each trade generates on average when you keep trading by the same set of rules. That is the core meaning of trade expectancy.
First, what is trade expectancy?
Trade expectancy (EV) is a metric that combines win rate, average profit, and average loss to estimate the long-term average outcom
