What Is Out-of-Sample Testing? Why Can Data Not Used to Optimize a Strategy Better Reveal Its True Capabilities?
In cryptocurrency trading, a strategy may perform well in historical backtests but quickly fail under new market conditions. The problem may not lie in the trading logic itself; the strategy may instead be overfitted to the historical data used for optimization. Out-of-sample testing is an important way to identify this issue.
First, what is out-of-sample testing?
Out-of-sample testing means using data that was not involved in strategy development or parameter optimization to indepe

What Is a Stop-Loss? Why Doesn’t Setting One Completely Prevent Losses?
In cryptocurrency trading, a stop-loss is an important risk management tool, but many traders mistakenly believe that setting one will strictly limit losses to the expected range. In reality, a stop-loss can help execute a risk plan, but it cannot guarantee the final execution price.
First, what is a stop-loss?
A stop-loss is an order to close a position or sell when the price reaches a preset condition, in order to limit potential losses. For example, if the price falls below a predetermined risk level after you buy, you

Hyperliquid’s earning power is getting a little terrifying! 😂
The data shows that Hyperliquid has already earned $557 million in the first 10 months of this year, and its annualized revenue over the past three months exceeds $800 million.
What does that mean?
Its revenue over the past 30 days was about 1.6 times that of , 13 times Aave’s, and 15 times GMX’s.
In traditional financial markets, Nasdaq’s 2025 net revenue from Market Services was about $1.2 billion, while Hyperliquid’s revenue, simply annualized based on the first 10 months, is already equivalent to 56% of that.
It already has the

What Is the Difference Between Isolated and Cross Margin? Which Margin Mode Is Better for Risk Control?
In crypto futures trading, margin mode can affect account risk, in addition to leverage. Isolated and cross margin are two common options. Their key difference is whether other funds in the account are used to bear the 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 mainly covered by the margin allocated to it, and other funds in the account are not automatically used

- Qualcomm and Arm Earnings Today: Why $QCOM and $ARM Will Decide The Next Chip Rebound
All eyes are on two names today. $QCOM and $ARM.
Qualcomm shares are in focus on Wall Street on Wednesday, November 4, as the semiconductor manufacturer prepares to announce its fourth-quarter fiscal 2026 financial results after the US stock market closes.
This is not a normal earnings day. This is the day that decides if the chip stocks rebound we saw yesterday continues, or fails.

Bitcoin Is Showing Signs of Recovery.
BTC is trading near $78,457, up 2.02% today.
Price has moved above the 7 day average, showing short term strength. However, the 30 day average near $81,011 remains the next major test.
A break above $81K could strengthen bullish momentum. The $73K area remains key support.

A-shares have stabilized and are now moving in the right direction. In this phase, try to avoid buying and selling back and forth or trading too frequently. If you pick the main theme, you can make a bit more; if not, you can still make a bit less. But if a position breaks down, you should still sell. My holdings are unchanged.

What Is a False Breakout? How Can You Distinguish a Brief Price Cross from a Valid Breakout That Could Signal a New Trend?
In crypto trading, many people immediately chase prices when they break above key resistance, and rush to short when they fall below support. But sometimes the price only briefly moves past a key level before quickly returning to its original range. This phenomenon is known as a false breakout, and it is one of the risks traders can easily overlook.

A false breakout occurs when the price briefly breaks through support or resistance but fail

$TRUMP Trading at 1.259, down 16.51% over 24H, with a range of 1.218–1.524. The 1H trend is weak, with RSI at 52.85 below EMA20 at 1.314; the 4H trend is weak, with RSI at 10.42 far below EMA20 at 1.469. The volume ratio is only 0.18, indicating insufficient buying pressure. A move higher requires holding above the 1.524 resistance; a break below the 1.218 support could signal further weakness. Key points to review: whether 1.524 can hold and whether price can recover after losing 1.218. With the volume ratio at 0.18, a single break through either level needs confirmation from participation; a

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.

Does a High Win Rate Mean the Strategy Is Excellent? Why Does Profitability Also Depend on the Risk-Reward Ratio?
In cryptocurrency trading, many people treat a high win rate as proof of strong trading ability, but frequent profits do not mean making money in the long run. If each win is small but a single loss is huge, the account may continue to shrink even with a high win rate. What really matters is the combined result of the win rate, risk-reward ratio, and trading costs.
First, what are the win rate and risk-reward ratio?
The win rate is the proportion of profitable trades out of all tra

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)
