What is look-ahead bias? Why can accidentally using future information in a backtest make an ordinary strategy look exceptionally good?

In cryptocurrency quantitative trading, a strategy’s high historical returns do not necessarily mean it has a genuine trading edge. If information that was not yet available at the time is used during a backtest, it can create look-ahead bias, allowing the strategy to know in advance what will happen and produce results that cannot be replicated in real trading.

First, what is look-ahead bias?

Look-ahead bias refers to mistakenly using future information wh

$BABYDOGE Looking at the weekly chart is depressing; switching to the 1M chart leaves no hope at all. The project was launched to save stray dogs, but I haven’t seen any dogs being saved—only more and more “seven-course dog meat feasts.” Baby Doge holders are looking more and more like dog bones: skin and bones, with their wallets shrinking by the hour, let alone by the day, month, or year.

Ethereum Briefly Falls Below $2,000: A Market Warning That Traders Should Not Ignore

The Unexpected Drop

Imagine opening your crypto portfolio, expecting another ordinary trading day. You check Ethereum, and something immediately catches your attention. ETH, one of the largest cryptocurrencies in the market, has fallen below $2,000.

For many investors, this is more than just another red candle on a price chart. The $2,000 level has become an important psychological price point, and losing it has raised fresh questions about market confidence, selling pressure, a

AI stock investors, don't panic! Jensen Huang has left Nvidia, but these five words are what really determine the fate of the AI bull market!

If Jensen Huang leaves Nvidia, does that mean the AI bull market is over?
Don't rush to sell everything, and don't rush to buy the dip.
When judging the future of the AI industry, the most important thing isn't whether a particular CEO remains at the helm, but five Chinese characters: commercialization capability.
No matter how advanced AI technology is, it will be difficult to sustain high valuations over the long term if it can't generate real revenue

What Is Slippage? Why Can the Price You See Before Placing an Order Change by the Time It Is Executed?

In crypto trading, you may have encountered this situation: the price you see before placing an order looks ideal, but after the order is filled, the actual execution price is higher than expected, or the selling price is lower than expected.

This difference between the expected price and the actual execution price is generally called slippage.

First, how does slippage occur?

The most common causes include rapid market fluctuations, insufficient order book depth, and an order size that is

What does it mean when prices rise, trading volume increases, and OI rises at the same time?

In the crypto futures market, traders often pay attention to a particular combination: prices rise, trading volume increases, and open interest (OI) also rises.

Some consider this a sign of a strong rally, while others worry that the market is accumulating too much leverage. So how should this be interpreted?

The key is that these metrics can provide information about market participation, but they cannot, on their own, prove that prices will continue to rise.

First, what does a price increase indi

What Is Open Interest (OI)? Why Doesn’t Rising Open Interest Necessarily Mean Prices Will Rise Soon?

In crypto futures trading, many people see open interest rising steadily and assume the market is about to rally. But open interest reflects the size of contracts that have not yet been closed, not simply buying capital. To properly understand market movements, OI must be analyzed alongside price, trading volume, and funding rates.

First, what is OI?

Open interest (OI) refers to the total number of contracts that have not yet been closed at a given point in time. OI may increase when new con

Why Can Prices Continue to Fall Even When MACD Shows Bullish Divergence?

In the crypto market, MACD bullish divergence is often seen as a potential reversal signal, but many traders find that prices can continue to fall even after bullish divergence appears. This is because weakening momentum does not mean the downtrend is over.

First, what is MACD bullish divergence?

When prices keep making new lows while the MACD indicator’s lows gradually rise, bullish divergence may be forming. This means downward momentum may be weakening, but it does not prove that buyers have taken control.

Second,

Why is a retest of a key level after a price breakout sometimes an important clue for judging trend strength?

In the crypto market, a price breakout above resistance does not necessarily lead to an immediate, sustained rise. Sometimes the price returns to near the breakout level before choosing a direction. This is known as a retest, and it can help traders assess whether the breakout has received further confirmation.

First, what is a retest?

A retest occurs when the price breaks above a key resistance level, then returns to test the area. The former resistance may turn into support, but t

The AI Godfather Exits—Who Will Be the Biggest Winner? Have AMD and Broadcom Finally Got Their Chance?

Who will be happiest if NVIDIA suddenly loses its soul, Jensen Huang?
Probably not NVIDIA shareholders, but the competitors that have long wanted a slice of the AI chip market.
AMD, Broadcom, and other AI chip-related companies may attract renewed market attention. The reason is simple: when an industry leader undergoes a management change, capital naturally starts looking for alternatives.
AMD's strength lies in its GPU product lineup, while Broadcom has its own competitive edge in custom A

Why Is the Liquidation Price Usually Closer to the Entry Price at Higher Leverage?

In crypto futures trading, leverage allows traders to open a larger notional position with less margin, but it also amplifies the impact of price fluctuations on account equity.

Many people know that higher leverage carries greater risk, but may not understand why: why can even a small price move put a highly leveraged position at risk of liquidation?

First, leverage changes the relationship between margin and position size.

Suppose you use 100 USDT as margin, in a simplified scenario that excludes fees and

Will Jensen Huang’s departure shift AI chip orders elsewhere? This industry-chain shake-up is only just beginning!

With Huang leaving, what matters most is not who takes his seat at Nvidia, but whether global AI chip orders will shift.
Nvidia has long held an important position in the AI accelerator market, and its influence has already extended to server manufacturers, cloud service providers, chip foundries, memory makers, and data center suppliers.
If the new management team can maintain the existing strategy and customer relationships, the industry chain may continue to develop at its est
