What is rolling backtesting? Why is continuously updating the test window more informative than testing just one historical period?
In cryptocurrency trading, a strategy may perform well only during a certain period of historical market conditions but fail to adapt to subsequent market changes. Testing just one fixed period can easily overlook how the strategy performs in different environments. Rolling backtesting continuously updates the test window, helping traders assess a strategy's stability more comprehensively.
First, what is rolling backtesting?

What Is Out-of-Sample Testing? Why Can Data Not Used to Optimize a Strategy Better Test Its True Capabilities?
In cryptocurrency trading, a strategy may perform well in historical backtests yet quickly fail in new market conditions. The problem may not necessarily 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 issue.
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 in

The easiest mistake to make in a bull market: mistaking luck for skill.
When the cryptocurrency market starts rising, you'll find that it suddenly seems like there are a lot of trading experts around you.
Someone buys a token and their account quickly doubles; someone correctly anticipates a market move; and someone else gets good results from several trades in a row.
Social media starts filling up with profit screenshots, accurate predictions, and success stories.
Everyone seems to have their own method, and everyone can explain why they made money.
But at this point, we should ask ourselves

What Is the Long-Short Ratio? Why Doesn’t a Higher Number of Longs Mean the Market Will Definitely Rise?
In cryptocurrency trading, many people see the long-short ratio rise and assume bullish sentiment is strengthening, then choose to go long. But market sentiment and actual price movements do not always align. The long-short ratio can help us understand traders’ positioning bias, 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 market. However,

#USNonfarmPayrolls
Navigating the NFP Storm: The Good News is Bad News Paradox
The recent ADP employment report surprised to the upside, adding 86,000 jobs in October. While this highlights economic resilience, the upcoming official Nonfarm Payrolls release is creating a complex setup for risk assets.
Let us break down the questions every trader is asking right now.
Is better data always more bullish, or is a moderate cooling better for the market? It is rarely that simple. We are currently in a macroeconomic environment where good news is bad news for risk assets. Stronger-than-expected data

Nearly $290 million in Bitcoin shorts were liquidated in a single day - the most since September 21. Funding has remained positive since May.
Will there be enough fresh buying to sustain the rally after the shorts are closed?

Bitcoin is holding steady at elevated levels and absorbing selling pressure this time, unlike previous rallies that quickly faded; buyers are providing strong support. The 90-minute MACD is bearish at high levels, and with nonfarm payrolls tomorrow, volatility will increase. $BTC $ETH

BTC has risen nearly 6,000 this round. I imagine quite a few people got caught in losing positions. I’ve been calling for longs at 76,500 for days—do you still want to short?
Being stuck in a losing position isn’t scary; what’s scary is not knowing how high it could go. It’s been moving sideways around 80k without breaking below it. Honestly, the bulls are pretty strong this time. If you’re not too deep in the hole, let’s fight back!!!$BTC $ETH #BTC重返8万

BTC retested 75600 yesterday to induce shorts
Staged a “Big V Tianlong” reversal, shooting straight up to 81000
Took out both longs and shorts, catching shorts at 76000 and longs at 80000
What’s the outlook for BTC today?
On the 4-hour chart, it tested the previous high of 82000 but failed to break through. Still, it’s holding firmly above 80000, and the pullback hasn’t been very strong. Bulls have the upper hand, so the strategy remains to buy dips
Go long at 78300–78800
Targets: 82000/83000
I’ve been telling everyone to enter longs at 76500, and now the results are clear. The bullish call and long execution have played out $BTC $ETH #BTC重返8万

What Is Overfitting? Why Can More Fine-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 the real market, their performance may 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 coincidental patterns in historical data, causing it to perform well in the past but lack the ability to ad
