What Is Out-of-Sample Testing? How Can Data Not Used in Strategy Optimization Help Determine Whether Backtest Results Are Meaningful?

In cryptocurrency trading, even a strategy that performs well in historical backtests may simply be tailored to specific data. Out-of-sample testing uses data that was not involved in strategy design or parameter optimization to check whether the strategy remains effective in unknown market conditions, reducing the risk of misjudgments caused by overfitting.

First, what is out-of-sample testing?

Data used to develop a strategy is called in-sample data, while

Understand DeFi Protocols: Don’t Just Focus on APY—Where Does Yield Come From? Who Bears the Risk?

In DeFi (decentralized finance), one question that’s easy to overlook is: when a protocol displays an attractive annual percentage yield, where does that yield actually come from?

APY is just a way of displaying the result; it cannot by itself prove that a protocol is worth participating in.

To assess whether a DeFi protocol is sustainable, consider these four aspects.

I. Where does the yield come from?

Yield may come from interest paid by borrowers, trading fees, liquidity incentives, or to

#美国10月CPI全面超预期 #每周来晒 The Fed doesn’t need to “turn hawkish”; it only needs to maintain a hawkish stance.

I. There are three levels to “turning hawkish,” and the market has only priced in the first
First level: a 25-basis-point hike in December. The probability is 88.5%, already fully priced in. This isn’t turning hawkish; it’s confirmation.
Second level: a one-off 50-basis-point hike in December. The probability jumped from 0% before the release to 11.5%. This is a real “hawkish turn,” and it’s also the line Waller drew himself just hours before the data: a core monthly increase of 0.3% or hi

Bad Boy Watch: SPCX Update 11.11
The Big Rocket closed at 143.09 in U.S. trading on Tuesday, up 0.72%. Its intraday high was 144.89 and its low was 139.16.
Musk has been making moves lately. As long as the AI narrative continues, spcx can stay in an upward channel.
Looking at the candlestick chart, U.S. shares closed at the 20-day moving average. For any new buys, wait for the 5-day moving average to rise and form a golden cross with the 10- and 20-day moving averages. That would provide strong support for the spcx share price, allowing it to go on to make new highs.

How to Set Stop-Losses and Position Sizes? Protect Your Trading Account with Risk Management

In cryptocurrency trading, judging the market’s direction is certainly important. But even if you correctly predict the trend, an oversized position can expose you to unacceptable losses from a single pullback. Truly experienced traders consider not only where to enter, but also how much they can afford to lose and how much they should buy.

First, determine the maximum acceptable loss for a single trade. Suppose your account holds 10,000 USDT and you plan to limit the risk on each trade to 1% of your

If You Lose 10 Trades in a Row, How Can You Tell Whether Your Strategy Has Truly Failed?

In crypto futures trading, consecutive losses are a problem many traders encounter. The most dangerous thing is not the losses themselves, but beginning to doubt your strategy after a losing streak, changing parameters at random, or even continually increasing position sizes to try to win back your losses.

So, does losing 10 trades in a row mean your trading strategy has failed?

First, look at its historical win rate. If a strategy has a long-term win rate of 60%, then 10 consecutive losses are indeed u

What Is an Iceberg Order? How Can It Hide Part of an Order’s Quantity and Reduce the Visible Market Impact of Large Trades?

In cryptocurrency trading, placing a very large order directly on the order book may allow other market participants to infer trading intentions, which can affect prices and execution conditions. Iceberg orders limit how much of the total order is visible at once by displaying only part of the quantity and replenishing it after execution.

First, how do iceberg orders work?

Suppose you plan to buy 100 BTC but display only 10 BTC at a time. Once the displayed quantity is

Pavel Durov Says GRAM Is Still Undervalued

Telegram CEO Pavel Durov has shared a bullish view on GRAM, describing the token as “still ridiculously undervalued” and suggesting it deserves a place among CoinMarketCap’s top three cryptocurrencies.

His comments come as GRAM gained around 8% while much of the broader crypto market was under pressure.

The statement has brought fresh attention to GRAM, but there is an important difference between a founder's confidence and actual market performance.

Whether GRAM can build on this momentum will depend on sustained demand, adoption, liquidity, and

Crypto Market Morning Brief | November 11

Market Overview

Over the past 24 hours, the overall market has been weak, with sentiment in the fear zone. Stimulated by inflation data, prices dipped in the short term before rebounding slightly. BTC is currently holding steady near $73,700, while ETH and SOL are consolidating in tandem. Altcoins have fallen further, and overall market capital is contracting, with bullish sentiment remaining weak.

U.S. October CPI data came in above expectations. The inflation rebound fueled expectations of rate hikes, and Treasury yields rose, weigh

Stablecoins look like digital dollars, but why aren’t they the same as dollars in a bank?

In the cryptocurrency market, stablecoins are often used for trade settlement, asset holding, and on-chain payments. Many people believe that as long as a token’s price stays close to $1 over time, it can be treated as cash.

But a similar price does not mean the risks are the same.

I. Why can stablecoins maintain price stability?

Different stablecoins rely on different mechanisms to maintain their prices. Three common types are:

1. Fiat-backed

Why Can Both Longs and Shorts Be Liquidated at the Same Time? How Does the Market Wipe Out Both Sides?

In futures trading, there is a puzzling phenomenon: the market rises rapidly, liquidating a large number of shorts; then the price suddenly reverses and falls, and longs start getting liquidated one after another. How can the market make both longs and shorts pay the price within such a short time?

First, the market has large numbers of stop-loss orders and liquidation positions at different price levels. When the price quickly reaches a key area, it may trigger a large number of forced liq

Why Do Altcoins Rise Faster Than BTC and Potentially Fall More Sharply?

In the cryptocurrency market, a common phenomenon is that when BTC rises 3%, some altcoins may rise 10% or even more; but when BTC starts to fall, these altcoins may also see steeper declines. What exactly causes this?

First, market capitalization and liquidity differ. BTC has a larger market size, so it takes substantial capital to move its price significantly. Some altcoins have smaller market caps, making them more prone to sharp fluctuations when capital flows in. But lower liquidity also means large sell orders can
