What Is Overfitting? Why Can More Finely Tuned Parameters Make a Strategy More Fragile?
In cryptocurrency trading, some strategies show increasingly high historical returns and increasingly attractive backtest curves after repeated parameter adjustments. However, once they enter live markets, their performance can quickly deteriorate. A common reason behind this is overfitting.
First, what is overfitting?
Overfitting occurs when a strategy adapts too closely to specific fluctuations and chance patterns in historical data, leading it to perform well in the past but lack the ability to adapt to

Market action can never escape structure!
Posted publicly in advance for all to see: short at 4136, add to the position at 4143; gold peaked at 4146.79 before falling to 4109.
Precisely called the top, precisely added to the position, and precisely captured the pullback swing—the timing, levels, and trend were all nailed! $XAU ‌

What is leverage? Why does higher leverage often leave less room for error in trading?
In cryptocurrency trading, leverage allows traders to control larger positions with less margin, but it does not make market risk disappear. On the contrary, the higher the leverage, the greater the impact that price movements of the same magnitude usually have on margin.
First, what is leverage?
Leverage is a way to control a larger trading position using margin. For example, with other factors ignored, using 10x leverage, 100 USDT in margin can be used to open a notional position of about 1,000 USDT. But t

How should position size be calculated? Why is it more reasonable to determine the risk amount first and then decide how much to buy?
In cryptocurrency trading, many people tend to assess the market first and then decide how much to buy, overlooking the most important step: if their judgment is wrong, how much of a loss can they actually afford to take? Sound position management should start with a risk budget, not potential returns.
First, determine the risk amount you can afford.
Suppose you have 1,000 USDT in your account and plan to limit the risk on a single trade to 1% of your account ba

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

Machi Big Brother is making a killing again!
He’s not only going long but also adding to his position, using 25x leverage to build from over 2,000 contracts to nearly 6,700. His latest average entry price is 2366, and his unrealized profit has surged past $460k, but his liquidation price has also been pushed up to 2391.
Big Brother is charging ahead with full confidence, but I’m actually not very bullish on this move in the short term. I recommend positioning for shorts around 2450.
The reasoning is simple:
This rebound after the election results came in looks more like a short squeeze followi

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.
