What Is a Margin Call? Essential Risk Alerts for Traders
In the world of leveraged trading, there is a term that makes many traders nervous—margin call. Simply put, this is your "account loss alert."
When you trade with leverage, you only need to put in a portion of the funds to control a larger position. But this "double-edged sword" also means that if the market moves unfavorably, your losses can quickly deplete your margin. When the margin in your account falls below the minimum requirement set by your broker, they will send you a "margin call" notification—meaning you must immediately add funds to your account or actively close positions to reduce losses. If you do neither, the broker has the right to forcibly close your positions.
Margin Level: The Vital Sign of Your Trading Account
Understanding the margin level is like knowing your "health bar" in a game.

The true picture of the current AI investment boom
Since ChatGPT made its debut at the end of 2022, artificial intelligence stocks have become the most dazzling stars in the capital markets. But is this wave of enthusiasm a bubble or real gold and silver? Data suggests it might be more substantial than you think.
According to the latest report from IDC, global enterprise spending on AI solutions and technologies is expected to reach $307 billion by 2025. This is just the appetizer—by 2028, the entire AI industry (including applications, infrastructure, and services) could surpass $632 billion, with a compound annual growth rate of about 29%. Among these, spending on high-performance servers supporting AI operations will account for over 75% of the total investment.
These figures confirm a market reality: the AI industry is moving from concept to actual implementation, with institutional investors and hedge funds significantly increasing their positions. For example, Bridgewater Fund (Br

Gold prices soar to new highs, is there still room for further increase?
Since October 2023, gold prices have entered an upward trend. In just two years, prices have risen from the initial level to break through $2,700 in October 2024, then hit a new high in October 2025, surpassing the $4,200 mark. Such a rally naturally raises the question: Is it worth buying gold now? Or should investors wait for a pullback before entering?
According to survey data from Reuters on market analysts, the average price of gold in 2025 may remain around $3,400 for the whole year, and by 2026, the average price is expected to further rise to approximately $4,275. This indicates that there is still significant medium- to long-term upside potential for gold, but the current price level is already quite high, and blindly chasing the high carries considerable risk.
Why does gold continue to hit new highs?
Gold itself does not generate interest, and its price changes are

The Australian dollar is the fifth most traded currency globally, and the AUD/USD currency pair is also among the most actively traded in the world. Its features of high liquidity and low spreads allow traders to operate more flexibly. However, despite being considered a high-yield currency in the past, the AUD has shown persistent weakness over the last decade. To understand the reasons behind the AUD's decline, a comprehensive analysis from macroeconomic, interest rate differential, and commodity price perspectives is necessary.
Reasons for AUD Decline: A Structural Decline Over Ten Years
The weakness of the AUD is not a short-term phenomenon. From the 1.05 level in early 2013 to today, the AUD/USD has depreciated by over 35% in ten years, while the US dollar index (DXY) has appreciated by 28.35%. This reflects a global "strong dollar cycle."
The main reasons for the AUD's decline include three aspects:
First, global commodity demand is weak. Australia's export structure is highly dependent on raw materials such as iron ore, coal, and energy. When the Chinese economy

What exactly is blockchain? Explained in one simple sentence
Imagine a ledger that records every incoming and outgoing transaction. A traditional ledger is kept by one person or organization, but this "ledger" called blockchain is maintained collectively by thousands of computers worldwide. No one can control it alone, and no one can arbitrarily alter it—that's the core of blockchain.
Why is it called "blockchain"? Because each transaction is recorded in a block, like a page in a ledger. When a page is filled, it automatically forms a new block. These blocks are linked together in chronological order using cryptography, like a chain, hence the name "blockchain."
Who maintains this "global ledger"?
On the blockchain network, there are a group of people called "miners" or "nodes." As long as you have a computer and internet connection, anyone can join and become a maintainer of this ledger. This multi-party participation model has

In the world of technical analysis, the KDJ indicator has always held an important position. What exactly does KDJ mean? In simple terms, it is a stochastic indicator that helps traders determine overbought and oversold conditions in the market and catch turning points. Why do so many retail and professional traders rely on it? This article will reveal the true power of the KDJ indicator through practical cases and in-depth analysis.
Let's start with a practical example: the classic operation case of the Hang Seng Index in 2016.
In early 2016, the Hong Kong Hang Seng Index experienced a deep correction. Many investors watched the index fall continuously and felt hopeless. But savvy traders noticed the signs of a reversal — stock prices kept making new lows, while the KDJ indicator was rising. This is a typical bottom divergence pattern.
On February 19, the Hang Seng Index opened high and moved higher, creating a large bullish candlestick of 965 points, with a gain of 5.27%. Wise investors had already positioned at the bottom and easily captured this upward move.

Why are investors关注 the crude oil market?
Crude oil is the most traded commodity globally and the lifeblood of modern economies. International oil price fluctuations not only impact energy companies but also influence the entire supply chain. For retail investors interested in crude oil investment, directly trading futures is too high a barrier, and holding physical oil is impractical. Therefore, oil ETFs have emerged as the most popular alternative.
In addition to ETFs, investors can participate in crude oil trading through various channels such as futures contracts, energy stocks, options, and CFDs. But among these options, why does crude oil ETF stand out? This guide will provide you with detailed answers.
Core Mechanism of Oil ETFs
Crude oil ETFs generally do not hold physical oil directly but instead invest in crude oil futures or forward contracts, swaps, and other financial derivatives that track crude oil futures prices or specific crude oil indices, thereby indirectly following the price trend of crude oil.

What are Derivatives? An Article on Mastering the Core Concepts
Looking back at the world of financial investment, we have encountered various assets such as stocks, foreign exchange, commodities, indices, and virtual currencies. Derivatives are financial contracts derived from these underlying assets.
Derivatives are essentially tradable financial contracts whose value depends entirely on the price movements of the underlying assets. When stocks, bonds, commodities, indices, or interest rates fluctuate, the prices of derivatives tracking these assets also change accordingly.
For example, if you want to invest in 1 BTC (assuming the current price is $95,000), the traditional approach is to buy Bitcoin directly on an exchange and wait for appreciation. However, through derivatives like Bitcoin contracts for difference (CFDs), you only need to put up a small margin to control an equivalent Bitcoin position — this is the core appeal of derivatives: achieving greater investment exposure with less capital.

Bitcoin's price journey tells a repeating story: supply constraints trigger momentum phases, euphoric peaks emerge, then extended cool-down periods follow. The pattern repeated in 2025—BTC surged to approximately $126,000 in October, then retreated sharply. Current data shows Bitcoin trading at $91.

By December 2025, the Taiwanese dollar against the Japanese yen has reached the 4.85 threshold, with an annual increase of 8.7%. Behind this exchange rate fluctuation, there are actually many currency exchange opportunities. As the Bank of Japan's interest rate hike expectations heat up (hawkish analysts expect a rate hike to 0.75% on December 19, reaching a 30-year high), the yen's safe-haven attribute has regained attention. Coupled with the recovery of tourism driving a 25% growth in currency exchange demand, now is a great time to understand the yen exchange strategy.
Why exchange yen now? Three levels of demand driving
Travel and Consumption
Japan's reliance on cash is much higher than imagined—credit card penetration in Japan is only 60%. This means that whether shopping in Shibuya, Tokyo, enjoying gourmet food in Dotonbori, Osaka, skiing in Hokkaido, or diving in Okinawa, most transactions still require cash. The purchasing market has also boosted currency exchange demand, as Taiwanese consumers who like Japanese cosmetics, clothing, and anime peripherals often need to pay directly in yen.
Financial Hedging

The RMB has recently appreciated strongly, breaking through the long-term resistance level of 7, mainly influenced by the weakening of the US dollar, support from the People's Bank of China's policies, and the year-end foreign exchange settlement surge. Several institutions predict that the RMB is still undervalued and expect it to continue appreciating in the future. Key factors include the direction of monetary policy, trade patterns, and the trend of the US dollar index.

International investment banks generally believe that the RMB still has room to appreciate in 2026. Goldman Sachs predicts the USD to RMB exchange rate will fall to 6.90, while ANZ Bank believes it will fluctuate between 6.95-7.00. The recent strength of the RMB breaking through 7 is due to factors such as a weakening US dollar, the People's Bank of China's guidance for appreciation, and the year-end foreign exchange settlement surge. This appreciation has a positive impact on China's capital markets, and the unchanged interest rate policy stance also supports the RMB's upward movement.
