What Is the Bid-Ask Spread? Why Can Even a Seemingly Small Spread Eat Into Returns Through Frequent Trading?

In crypto trading, many people focus only on price movements and overlook the spread between buying and selling. Even when market prices show no significant change, frequent trading can still incur ongoing costs from spreads and fees, ultimately affecting actual returns.

First, what is the bid-ask spread?

The bid-ask spread is the difference between the market’s best ask price and best bid price. For example, if an asset’s best bid is 100 USDT and its best ask is 100.10 USDT, the spr

Nvidia at $165: are you selling at a loss or picking up a bargain?

Jensen Huang suddenly resigns, the stock drops from 243 to 148, and volume explodes to 750 million shares. But just as everyone panics, someone quietly scoops up shares after hours at 167.8. Is this a golden opportunity to buy the dip, or a falling knife?

First, look at the surface: the sky is falling, but the price hasn't collapsed.

On November 12, Nvidia's board announced that Jensen Huang was resigning immediately as CEO, president, and director, citing two extramarital affair scandals. The stock opened and plunged straig

What Is Breakout Trading? How Can You Tell Whether Price May Continue Trending After Breaking a Key Level Rather Than Falling Into a False Breakout?

In the cryptocurrency market, when prices break through important resistance or fall below key support, they often attract considerable attention from traders. Some choose to enter in the direction of the trend, hoping to catch the start of a new trend; others suffer losses from chasing prices amid false breakouts. What really matters is not whether the price crosses a line, but whether the breakout receives further confirmation from the market.

#Gate股票畅聊季 Jensen Huang really is leaving! Nvidia plunged as much as 14% intraday, yet some Wall Street investors are aggressively buying the dip?

Why Is Trading Volume Not Hitting New Highs Alongside Price?

In the crypto market, prices keep reaching new highs, and the trend still looks strong, but trading volume is gradually shrinking. This phenomenon is worth watching because it may reflect a change in market participation. However, declining volume does not necessarily mean a reversal is imminent.

First, upward momentum may be weakening.

A new high indicates that buyers and sellers are transacting at higher prices under current conditions, but if volume is not rising in tandem, it may mean there are not enough new participants. If

Why doesn’t price necessarily fall immediately when MACD shows bearish divergence?

In the crypto market, when prices keep making new highs while the peaks of the MACD indicator gradually decline, bearish divergence may form. Many traders view it as a short signal, but bearish divergence reflects a possible weakening in upward momentum; it does not mean that prices will necessarily fall immediately.

First, understand what bearish divergence means.

Bearish divergence typically appears when price peaks keep rising while the corresponding MACD peaks gradually decline. This may indicate that upw

What Is Out-of-Sample Testing? Why Can Data That Was Not Used to Optimize a Strategy Better Test Its True Capabilities?

In cryptocurrency trading, a strategy may perform well in historical backtests but quickly fail in new market conditions. The problem may not lie in the trading logic itself; the strategy may also be overfitted to the historical data used for optimization. Out-of-sample testing is an important way to identify this problem.

First, what is out-of-sample testing?

Out-of-sample testing means using data that was not involved in strategy development or parameter optimization to

What is arbitrage trading? Why doesn't a price difference for the same crypto asset across different markets necessarily mean there is risk-free profit?

In cryptocurrency markets, the same asset may be quoted at different prices on different exchanges, and a spread may also exist between spot and futures markets. Arbitrage trading seeks to profit from these differences, but when trades are actually executed, fees, slippage, transfer delays, and market volatility can all erase seemingly certain profits.
