Recently, I went through my own trading notes and found that many losing trades were caused by not truly understanding K-line reversal signals. To be honest, technical analysis may look simple, but using it well definitely takes effort.
Let’s first talk about a phenomenon. When the domestic stock market opened in 1990, K-lines were introduced directly. But over the years, most research on K-lines has still remained within the old Japanese playbook: scattered statistics of single K-lines, double K-lines, and multiple K-lines—nothing truly systematic has been formed. After trading for so many ye

Recently, someone asked me what exactly the annual percentage rate (APR) means, and I found that many people actually confuse APR and APY. These two concepts are really quite different in investing and lending.
Let's start with APR, which is the annual interest rate. The calculation is very simple, based solely on your principal, without considering compounding. If you borrow or invest money, APR directly tells you how much interest you'll pay or earn in a year. Credit card rates, consumer loans, and mortgages are usually expressed using APR. But there's a problem here: because APR doesn't inc

Recently, I came across a pretty frightening case. Someone bought a so-called "cold wallet" on social media, and overnight, 50 million was gone—truly a bloody lesson.
Actually, many beginners don’t understand the difference between cold wallets and hot wallets. Simply put, a cold wallet is a completely offline physical device, like an upgraded USB drive, not connected to the internet during normal use, only plugged in when needed. A hot wallet, on the other hand, is a software wallet that is always online, convenient and quick. Large-scale investors usually choose cold wallets for long-term st

Recently, I’ve been pondering a question: why is blockchain technology so impressive, yet it has never achieved widespread adoption? The answer might lie in the so-called "trilemma."
In simple terms, it’s nearly impossible for a blockchain to excel in three areas at once: decentralization, security, and scalability. Want all three? That’s difficult. Usually, you have to sacrifice one or two.
Let’s first look at the current situation. The Bitcoin network can process about 7 transactions per second, and Ethereum only around 15. In comparison, centralized payment systems like Visa can handle 24k

Speaking of V God and Ethereum, I recently recalled this legendary story and couldn't help but want to share it.
In 2014, during his trip to China, V God distributed 5,000 Ether tokens at a conference in Hangzhou. What happened next? Most people thought he was a scammer and didn't believe it at all. But do you know what happened later? Those 5,000 tokens given away for free eventually skyrocketed to $150 million. This is the story of Ethereum brought by V God, even more exciting than Bitcoin.
I'm quite curious why V God chose this path. I heard that between the ages of 13 and 16, he was obsess

Recently, many beginners have been struggling with contract trading, mainly because they don't understand the basic concepts of opening positions, closing positions, and holding positions. To be honest, these three terms seem complicated, but once you understand them, they are very simple. Today, I will break them down and explain.
Opening a position is actually the process of entering the market to establish a position. When you believe a certain coin will go up, you buy to establish a long position, which is called opening a long position. Conversely, if you think it will fall, you can sell

Eight years ago when returning to China to start a business, Sun Yuchen once said in a speech: "My standard for judging a person is how much money they make." This is not just a slogan, but has been his guiding principle in action. From starting his business in 2014 to becoming the head of a publicly listed company at age 35 this year, Sun Yuchen has demonstrated what it means to "maximize the use of rules" through concrete actions.
Recently, this deal has attracted a lot of attention—Sun Yuchen used $100 million to reverse acquire the U.S. publicly traded company SRM Entertainment, allowing T

In trading, people often talk about top divergence and bottom divergence, but many actually don't quite understand what these two concepts are really referring to. I'll just share my understanding directly.
Simply put, divergence is a situation where price and indicators are not synchronized. When you're analyzing the market, if you find that the price is rising but the indicator is falling, or the price is falling but the indicator is rising, that's divergence. Most of the time, when we talk about divergence, we're referring to RSI or MACD indicators.
Let's start with top divergence. This occ

Recently, I was explaining moving average parameters to a friend and realized that many people simply don't understand what a 5MA is, let alone how to use it. Actually, this is a good question because the core of any moving average strategy lies in parameter settings. Setting them correctly can greatly improve your trading success rate, while setting them wrong will only lead to frequent stop-losses.
Let's start with the basics. The 5MA is the average closing price of the past 5 candlesticks. It sounds simple, but it determines how sensitive the moving average is to price changes. When you set

Recently, someone asked me how to trade this inside bar pattern, so I might as well explain it systematically.
To be honest, the inside bar is one of the technical patterns I use most frequently in my trading career. It’s actually very simple: the price is completely contained within the range of the mother bar, with the highest and lowest prices not exceeding the boundaries of the previous mother bar. It looks simple, but to truly master the inside bar and use it effectively to guide your trading, you still need some skill.
When I first understood the inside bar, I saw it as a signal of marke

Recently, as I’ve been organizing some trading notes, I’ve found that many people still have misunderstandings about harmonic patterns. In fact, if you master this set of harmonic pattern analysis methods, it can indeed help you identify quite a few potential reversal opportunities—reportedly, the win rate can reach around 70–80%.
Let’s start with the simplest one. The ABCD pattern is an entry-level harmonic pattern: it’s a combination of three waves and four points. The impulsive wave is AB, then there’s a corrective wave BC, followed by another impulsive wave CD—the logic is straightforward.

After spending a long time in the crypto world, you've probably had this experience: watching your coins soar in value, thinking they'll keep going up, only to turn around and fall back down, with your original profits instantly evaporating. Or conversely, losing some money but being reluctant to sell, holding on and eventually losing so much that you can't bear it anymore.
Actually, these are classic examples of not properly implementing take-profit and stop-loss strategies. I’ve noticed that many beginners underestimate the importance of take-profit and stop-loss, thinking they are just tool

Recently, I’ve been pondering a question: why do so many people struggle with going long and going short? There’s actually a deep market logic behind it.
Let’s start with the appeal of shorting. Some people say that if you only go long, you won’t have opportunities to profit when the market falls. Plus, shorting can leverage contracts, and if technical analysis can predict rises, theoretically it can also predict declines. Add in the sense of superiority that “truth is in the hands of a few,” and shorting indeed has a kind of magnetic allure.
But I later realized that in the cryptocurrency spa

Oh my god, I just saw that the car influencer Chester Car is promoting an investment plan on IG—2% per month, 24% per year, with principal guaranteed and withdrawable at any time. You can tell at a glance something’s wrong. Netizens immediately blasted it, saying it’s basically a Ponzi scheme. I looked into his background and found out that he’s actually been involved in some pretty complicated stuff in the past.
He’s a car YouTuber with more than 100,000 subscribers, but in 2017 he was the only survivor of the Zhongli shooting incident. Back then, he was attacked by gunmen at an underground s

I have been studying the ICT trading system recently and found that the logic behind this methodology is actually very clear: it follows the behavior of major institutional funds to capture high-probability trading opportunities. Currently, more than 3 million people are paying attention to this system, but many still can't quite grasp the core principles.
Honestly, the core idea of ICT is just one sentence: big funds are the true drivers of price movement. They will first position themselves, then create liquidity, and finally push the price. If you can understand where the liquidity is, whic

Haha, when Musk asked "Where did Jack Ma go," I really couldn't stop laughing; everyone in the audience was laughing. The interaction between these two tech giants is quite interesting, and it seems there might be quite a few stories behind the question of where Jack Ma went.
By the way, the crypto market has been moving recently. XRP has been on a good rise lately, currently trading at $1.37, with a 24-hour increase of 0.29%. Many people are paying attention to the trends of these mainstream coins, but the meme about where Jack Ma went might be more popular than the market itself.
I wonder wh

Recently, I found that many people trade stocks by blindly buying and selling, completely ignoring the turnover rate. Honestly, if you don't even understand the turnover rate, watching the market is pointless. Today, I will thoroughly explain this concept because it is truly the best tool for finding main players and judging a stock's activity level.
Let's start with the simplest understanding: the turnover rate is the frequency of stock trading, reflecting how active this stock is. If a stock has a turnover rate of 60%, it indicates that the chips are being exchanged sufficiently and easily,

Recently, many beginners have questions about leveraged trading, so I think it's necessary to organize this topic.
Honestly, leveraged trading is like a double-edged sword. You use a small amount of capital to control a large position, which can double your profits, but also magnify your losses in the same way. That’s why I always emphasize—leverage trading is definitely not suitable for beginners.
First, let's talk about how it works. You open a margin account on an exchange, only need to pay a portion of the total order value as "margin," and the remaining funds are provided by the exchange

Recently, I’ve been studying the adjustment of MACD parameters and found that many traders have some misunderstandings about this indicator. I want to share some insights with everyone.
Speaking of MACD, most people use the default 12-26-9 parameters. This setting is indeed quite stable, but the problem is it may not be suitable for everyone. The fast EMA (12) captures short-term momentum, the slow EMA (26) looks at long-term trends, and the signal line EMA (9) filters out noise. Theoretically, it’s perfect, but in highly volatile markets like cryptocurrencies, sometimes the response is still
