What Is Out-of-Sample Testing? Why Can Data Not Used in Strategy Optimization Better Test a Strategy’s True Capabilities?

In cryptocurrency trading, a strategy may perform well in historical backtests yet quickly fail in new market conditions. The problem may not lie in the trading logic itself; the strategy may have simply become 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 uses data that was not involved in strategy development or parameter optimization

What is arbitrage trading? Why doesn’t a price difference for the same crypto asset across different markets necessarily mean there is risk-free profit?

In crypto markets, the same asset may have different quotes on different exchanges, and spreads may also exist between spot and futures markets. Arbitrage trading seeks to profit from these differences, but in practice, fees, slippage, transfer delays, and market volatility can all make seemingly certain profits disappear.

Jensen Huang admitted in his own words that the U.S. got its China chip policy wrong. Coming from Nvidia, that carries real weight. He acknowledged that he failed to persuade policymakers and that the company lost out on the huge Chinese market. If chip stocks are really going to catch up, it’ll depend on whether remarks like this can pressure policymakers to ease restrictions—not just empty talk. My bet is that things will stay deadlocked in the short term. I hope I’m wrong; if I am, it means the rally still has legs. What do you think Huang’s comments can achieve?

Gold continues to attract capital. Why hasn’t Bitcoin risen in tandem?

An interesting phenomenon has emerged in financial markets recently: Gold and Bitcoin are both seen by some investors as alternative assets outside the traditional financial system, but their capital flows have diverged significantly.

Data released by the World Gold Council on November 5 showed that global physically backed gold ETFs saw net inflows of about $2.7 billion in October 2026, marking their fourth consecutive month of net inflows. Global gold ETF holdings increased by 19 tons to 4,275 tons, setting a new month-

#USJoblessClaimsBeatExpectations
US Jobless Claims Rise Above Expectations — A Cooling Labor Market Could Complicate the Fed’s Next Move

The latest US employment data introduces another important variable into an already complicated economic environment. Initial jobless claims increased to 200,000, exceeding market expectations of 194,000. Although the difference is relatively small, the reading adds to signs that the American labor market may gradually be losing some momentum.

However, the bigger picture requires careful interpretation. At 200,000 claims, unemployment filings remain histor

From a Solo Founder to the Oxford Union: Dr. Han's Vision of Entrepreneurship in the AI Era

Building a successful company has traditionally required significant resources, a large workforce, and years of operational experience. Artificial intelligence is beginning to challenge that model, creating opportunities for individuals to accomplish what once required entire teams.

This was one of the central ideas behind Gate Founder and CEO Dr. Han's "Start Alone" speech at the Oxford Union, where he reflected on Gate's 13-year journey and shared his perspective on entrepreneurs

My path from $1,000 to a million had barely begun before it was already over.

The main reason was that I made a profit on my first buy of $ZEC but didn’t sell. I wanted to hold on and see how far it could go, but… it just kept falling.

BTC and ETH may have fallen like this, but they couldn’t liquidate me, because there were plenty of chances along the way to trade my way back to breakeven. But my funds were tied up in ZEC, so there was nothing I could do.

In short: stay away from altcoins when trading futures.

(The first time I traded SanDisk, I also lost over $30,000. If the profits I ma

What Is the Break-Even Win Rate? How Can You Calculate the Minimum Win Rate a Trading Strategy Needs to Cover Trading Costs?

In cryptocurrency trading, many people know their win rate but not how high it needs to be to actually make a profit. If winning trades earn little while losing trades lose a lot, you can still end up losing money even if you make the right call more often. The break-even win rate helps traders understand the minimum performance their strategy needs to achieve.

I’ve been watching this gold rebound for two days, and overall, it’s been pretty modest. The price action shows small bullish candles, with gains often fading after intraday highs. The rebound over the two days is still less than 1%, and gold hasn’t been able to reclaim the short-term moving averages in one go. The 5-day and 10-day moving averages are still overhead, acting as resistance, and trading volume hasn’t picked up noticeably. This looks more like tentative buying to cover short positions than a trend reversal. With similar geopolitical headlines, gold often follows a “rally in the mo

What is arbitrage trading? Why doesn't a price difference for the same crypto asset across different markets necessarily mean there is risk-free profit?

Nvidia CEO Jensen Huang abruptly resigned from the position he had held for 33 years after the board investigated his improper relationships with several subordinates and an affair with a customer suspected of working for Beijing. CFO Colette Kress has taken over on an interim basis.

Although he is gone, the massive leverage he built for the entire AI industry using the company’s balance sheet is still hanging in midair. Nvidia’s latest second-quarter 10-Q shows that total off-balance-sheet obligations surged from $184 billion last quarter to $530 billion.

What Is the Funding Rate? Why Can Perpetual Contracts Continue to Incur Holding Costs Even When Prices Barely Move?

In crypto 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, a nonzero funding rate can result in additional costs or earnings while holding a position.

The funding rate is a mechanism through which longs and shorts periodically pay each other fees in perpetual contracts, with the goal of keeping contract prices

Bitcoin ETFs Continue to See Outflows: What Signal Is the Market Sending?

Recently, the Bitcoin market has shown a phenomenon worth watching closely: U.S. spot Bitcoin ETFs are experiencing a significant wave of net outflows. This is not just a matter of price volatility; it also reflects some investors reassessing risk.

According to public data as of November 11, 2026, U.S. spot Bitcoin ETFs have seen cumulative net outflows of about $1.61 billion this month. On November 5, net outflows totaled about $430.2 million for the day, followed by $411.9 million in net outflows on November 6. Altho
