What Is Overfitting? Why Can More Fine-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 the real market, their performance may deteriorate rapidly. A common reason behind this is overfitting.
First, what is overfitting?
Overfitting occurs when a strategy adapts too closely to specific fluctuations and coincidental patterns in historical data, causing it to perform well in the past but lack the ability to ad

【11.4 BTC Strategy Review】
Yesterday's early-session outlook called for a pullback and adjustment, with a clear plan to go long near 76500 after support held, targeting 77500, 78200, and 79000 in sequence.
The intraday low reached around 75690, briefly dipping below the defense level before quickly recovering. After support was confirmed, a one-way rally began, reaching a high of 81188. All three preset targets were surpassed, fully capturing a rebound of nearly 5500 points.
From identifying support at the lower Bollinger Band to anticipating a breakout above the previous high resistance, the

What Is Trade Expectancy? Why Does It Better Reflect a Strategy’s Long-Term Profitability Than Win Rate Alone?
In cryptocurrency trading, a high win rate does not necessarily mean making money, and a low win rate does not necessarily mean losing money. What really matters is how much profit or loss each trade generates on average when you keep trading according to the same set of rules. This is the core meaning of trade expectancy.

What is rolling backtesting? Why is continuously updating the test window more informative than testing just one historical period?
In cryptocurrency trading, a strategy may perform well only during a certain period of historical market data, yet fail to adapt to subsequent market changes. Testing only one fixed period can overlook how the strategy performs under different conditions. Rolling backtesting helps traders evaluate a strategy’s stability more comprehensively by continually updating the test window.

What Is a False Breakout? How Can You Distinguish a Brief Price Break from a Breakout That May Lead to a New Trend?
In crypto trading, many people rush to buy when the price breaks through a key resistance level, and rush to short when it falls below support. But sometimes the price only briefly moves beyond a key level before quickly returning to its original range. This phenomenon is called a false breakout and is one of the risks traders can easily overlook.

The manufacturing association brought together business leaders, trade groups, and the economic cabinet in Caracas for its annual conference. The goal is ambitious: revive manufacturing and grow 14% in 2027, with the “Made in Venezuela” label on shelves at home and abroad.

BTC quickly rallied from around 78,300 to above 81,000, and has now returned to around 80,500 to trade sideways. Can we still trade tonight? Let me start with one point: the most dangerous thing right now isn’t getting the direction wrong, but seeing the move start and then rushing to enter.
I’ll break down tonight’s market using a multi-timeframe quantitative approach:

What Is the Funding Rate? Why Can Perpetual Contracts Continue to Generate Holding Costs Even When Prices Do Not Move Significantly?
In cryptocurrency trading, many people focus only on price movements after opening a position and overlook the funding rate. For perpetual contract traders, even if prices move sideways for a long time, holding a position may still incur additional costs or generate income as long as the funding rate is not zero.

The funding rate is a mechanism in perpetual contracts through which longs and shorts make periodic payments to each ot

Gate has officially launched Proof of Security, or PoSEC, extending beyond Proof of Reserves by disclosing the distribution of cold-storage and hot-wallet assets and introducing a cold storage coverage ratio to measure protection under extreme-risk scenarios. Gate’s latest cold storage coverage ratio stands at 104.58%, with 88.26% of assets in cold storage and 11.74% in hot wallets. A coverage ratio of at least 100% means cold-storage assets alone would still be sufficient to cover all user assets even if hot-wallet assets were fully lost. Exchange security is not only about whether reserves are sufficient, but also how assets are stored and protected under extreme conditions. Could cold storage coverage become a new industry standard?[👉 Learn more](https://gate.com/proof-of-security)
