What Is Overfitting? Why Can a Strategy Become More Fragile as Its Parameters Are Fine-Tuned?

In cryptocurrency trading, some strategies show increasingly high historical returns and increasingly impressive backtest curves after repeated parameter adjustments. However, once they enter the live market, their performance can deteriorate rapidly. A common reason behind this is overfitting.

First, what is overfitting?

Overfitting occurs when a strategy adapts too closely to specific fluctuations and accidental patterns in historical data, causing it to perform well in the past but lack the abil

#晒出我的持仓收益 Wait for key levels and try to get in early. As for 67,500, I’ll revisit it if 75 breaks down. You need to be patient. If you insist on trading every level, never staying out of the market and always being fully invested, you’ll never make money. How am I handling this trade? I had limit orders filled on both accounts. One account is for a short-term trade—I’ll take profits and exit. The other is protected at breakeven while I hold out for a better outcome. That’s all.

What Are Support and Resistance Levels? Why Do These Price Zones Often Influence Traders’ Decisions?

In crypto markets, prices do not fluctuate without a pattern. Certain zones repeatedly see buying or selling pressure, causing prices to temporarily stop falling or rising, or even reverse. These zones are commonly known as support and resistance levels, but they are not absolute price boundaries.

First, what is a support level?

A support level is an area where relatively strong buying may emerge as prices fall. As the price approaches this area, some traders may consider it attractive, incr

What Is the Sharpe Ratio? How Can You Measure Whether the Returns from a Trading Strategy Are Worth the Risk?

In cryptocurrency trading, a high return does not necessarily mean a strategy is good. If a strategy can generate high returns but comes with sharp volatility and significant drawdowns, we need to take a closer look: Are those returns worth the risk involved? The Sharpe ratio is one tool that can help answer this question.

First, what is the Sharpe ratio?

The Sharpe ratio measures the excess return earned by a portfolio or trading strategy per unit of volatility risk. Generally, the

The climb of the US Dollar Index (DXY) to a 19-month high is more than just a currency fluctuation; it is the clearest indicator of global capital seeking a "safe haven" and a repricing of risk appetite.

On November 11, 2026, the DXY rose by 0.68% to reach 102.90—its highest level since April 2025. So, what lies behind this surge, and what does it mean for the markets?

📈 Hot Inflation and a Hawkish Fed

The primary driver pushing the DXY to its peak was the US Consumer Price Index (CPI) data for October. Headline inflation rose by 0.4% month-on-month, exceeding the 0.3% forecast, while co

Jensen Huang resigns: the veteran trader with the biggest bet on Polymarket that he wouldn’t leave lost over $30k on this market. The new account registered in October that bet he would leave turned $6,000 into 40k🧐
I went back through the positions of both accounts.
The veteran had bought over $80k worth of “won’t leave” shares on this market. At 6 a.m. on the 12th, the news broke, and the odds of him stepping down jumped from 16% to 77% in an hour. He bought another $20k-plus worth during that hour.
Two hours later, he sold most of them at around 10 cents.
At 6 p.m., he bought in again, put

Nov 13 $ETH Market Update
The 1,900 level has been breached. What’s next?
Looking at the current market, the price bottomed just above 1,890, down more than 7% in 24 hours.
At the same time, $BTC also fell below 68,000, hitting its lowest level since Aug 20. The entire market plunged.
Since prices started falling, every rebound has been brief. There are few buyers and more sellers, so bears are still in control in the short term.
ETH liquidations totaled $104 million over 24 hours, with longs accounting for 89%. Most of the leveraged positions opened by dip buyers have been wiped out. But op

Please review and learn. Is the trend still the same? #XAU

Leveraged buyers took 87.5% of Nov 12's forced closures, on a day that ran above its 7 day average. On $BTC alone, $153.1M of longs were closed against $7.5M of shorts.

$ETH is showing signs of recovery after a sharp sell-off. On the 1-hour chart, bearish pressure remains heavy, with the price at one point pushed down to the support zone near $1,900. However, the latest bullish candles suggest buyers are tentatively stepping in. The key is whether the price can decisively move above $1,960—only a breakout above this level would truly open up the rebound structure.

Reference trading range: entry at $1,935–$1,945, target at $1,980, with defense at $1,910.
Position for the $ETH contract based on this setup, but wait for confirmation before acting.

Why Can Prices Rebound Quickly After Falling Below a Long-Term Moving Average?

In crypto markets, long-term moving averages are often used to track medium- to long-term trends. When prices fall below an important moving average, many traders assume a downtrend is now established. In reality, however, prices sometimes rebound quickly and climb back above the moving average. Understanding this phenomenon can help avoid making trading decisions based on a single signal.

First, long-term moving averages reflect historical prices. For example, MA120 reflects the average price over a certain perio

What Is the Market Pricing When the Spot-Futures Basis Widens?

In the crypto market, besides price, trading volume, and funding rates, there is another metric worth watching: the basis.

Sometimes, Bitcoin's spot price changes little, while its futures price is significantly higher than spot; at other times, the futures price is lower than spot. This difference is more than just a numerical change—it may also reflect differing expectations about future prices, funding costs, and demand for positions.

First, understand what the basis is.

The basis usually refers to the difference between the

I got liquidated—this market wiped out 120k U from me. At the beginning of this month, I posted 💰 with 90k and was still planning to grow my account to 250k U and send everyone 18 in red envelopes. Big Coin Bro just doesn’t have what it takes. No rush—everyone, wait for my last dance! Give me 12 hours and I’ll keep going with 17k U. I’ll continue sharing my trading plans publicly, no faking it.
