What Is a Market Maker? How Do They Improve Market Liquidity by Providing Bid and Ask Quotes, and What Risks Do They Face?

In crypto markets, whether a trade can be executed quickly depends not only on the willingness of buyers and sellers, but also on whether sufficient liquidity is available in the market. Market makers are important participants in providing market liquidity, but they are not risk-free intermediaries who always make a profit.

First, what is a market maker?

Market makers typically provide ongoing buy and sell quotes, making it easier for other traders to find counterparti

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

What is the difference between isolated and cross margin? Which margin mode is better for managing risk?

In crypto futures trading, margin mode, in addition to leverage, also affects account risk. Isolated and cross margin are two common options. The key difference is whether other funds in the account are used to absorb losses when a position loses value.

First, what is isolated margin?

Isolated margin assigns separate margin to a specific position. Typically, losses on that position are primarily covered by the margin allocated to it, and other funds in the account are not automatically u

How Should Position Size Be Calculated? Why Is It More Reasonable to Determine the Risk Amount First, Then Decide How Much to Buy?

In cryptocurrency trading, many people are used to assessing the market first and then deciding how much to buy, while overlooking the most important step: if they are wrong, how much of a loss can they actually afford to bear? Sound position management should start with a risk budget, not potential returns.

First, determine the amount of risk you can afford to take.

Suppose your account has 1,000 USDT and you plan to limit the risk on a single trade to 1% of yo

BTC at 68,500: Are you cutting or holding?
October CPI came in hot, the probability of a rate hike surged to 80%, ETFs saw $1.28 billion in outflows in a week, $1 billion in long positions were liquidated, and the Fear Index fell to 19. Everyone is calling for a crash. But just now, BTC bounced hard from 67,500 to 68,500—was this sharp drop the final shakeout, or a bull trap before a bigger plunge?

First, the surface picture: the screen is full of bearish news, but have you noticed one thing?

BTC has fallen from its ATH of 126,200 to 68,500, a 45% retracement. It dropped 6% in 24 hours, hitt

$ENA Current price: 0.1367. The Bollinger midline at 0.1430 is the first resistance, while the lower Bollinger band at 0.1341 is short-term support. Compared with peers in the same sector, $ENA 's 24h decline of 3.39% is notably smaller than $ETH 's 5.71%, and its RSI of 39.7 is also higher than $ETH 's 26.9. Its relative resilience amid extreme fear (index: 20) is the key point to watch. Technically, MA5 at 0.1359 has moved above the current price and is approaching MA20 at 0.1385, with the moving averages converging ahead of a potential move. The MACD histogram has turned positive at +0.000

What is the risk-reward ratio? Why can a trade have long-term value even with a low win rate, as long as risk is managed appropriately?

In cryptocurrency trading, many people focus too much on win rate, believing that they need to make correct calls frequently to make money. But what really affects long-term trading results is not just the win rate, but also the size of each win and loss. The risk-reward ratio is an important tool that helps traders assess whether a trade is worth taking.

First, what is the risk-reward ratio?

The risk-reward ratio generally compares a trade's potential loss

Bitcoin’s Fall Below $70,000 Signals a Deeper Shift in Market Sentiment — The Next Move Could Define Its Short-Term Direction

Bitcoin’s decline below $70,000 marks an important turning point in the current market structure. After trading considerably higher just days ago, the leading cryptocurrency is now testing price levels that could determine whether this correction develops into a deeper downturn or becomes the foundation for a recovery.

What makes this decline particularly significant is the combination of macroeconomic pressure, weakening institutional demand, and deterior

The crypto market is facing heavy selling pressure, with more than $440 million in positions liquidated within just one hour. Around $417 million came from long positions, showing how heavily leveraged bullish traders were affected by the sudden market decline.

Bitcoin dropped below $69,000, Ethereum fell under $1,950, and Solana slipped to $78.

Long liquidations happen when traders borrow funds or use leverage to bet on rising prices, but the market moves in the opposite direction. When their margin becomes insufficient, exchanges automatically close their positions to limit further losses.

ethereum:0x68749665ff8d2d112fa859aa293f07a622782f38 is currently trading at 3884.55, down 1.78% over 24H. The 1H outlook is weak, with price below the EMA20 at 3901 and RSI at 57; the 4H outlook is weaker, with the EMA20 at 3966 and RSI at 24, indicating downward alignment across both timeframes. The volume ratio is only 0.10x. Observation: A rebound is worth considering only if price holds above the 3959.04 resistance on increased volume; if it breaks below the 3850.48 support and fails to reclaim it, weakness may continue. Monitor whether price can hold above 3959.04; insufficient volume or

How can out-of-sample testing help prevent mistaking accidental patterns in historical market data for a lasting edge?

A trading strategy's strong performance in historical backtests does not mean it can adapt to future markets. To reduce the risk of overfitting, out-of-sample testing is a crucial step in validating a strategy.

First, what is out-of-sample testing?

Simply put, it means dividing historical data into different periods: one portion is used to develop the strategy and adjust its parameters, while another is excluded from optimization and reserved for evaluating how the strategy

What Is the Long/Short Ratio? Why Doesn’t a Higher Number of Longs Mean the Market Will Definitely Rise?

In crypto trading, many people see the long/short ratio rise and assume bullish sentiment is strengthening, then choose to chase long positions. But market sentiment and actual price movements do not always align. The long/short ratio can help us understand traders’ positioning tendencies, but it cannot directly determine how the market will move next.

First, what is the long/short ratio?

The long/short ratio measures the relative proportion of long and short positions in a particular ma

What are support and resistance levels? Why do these price zones influence traders’ decisions, yet are not absolutely reliable boundaries?

In cryptocurrency trading, prices often rebound or retreat repeatedly in certain zones. Traders usually call these zones support and resistance levels. They can help analyze market structure, but they do not guarantee that prices will rebound or reverse.

First, what are support and resistance levels?

A support level is a zone where buying may strengthen and a price decline may temporarily slow; a resistance level is a zone where selling may increase and
