What Is Out-of-Sample Testing? Why Can Data Not Used to Optimize a Strategy Better Reveal Its True Capabilities?
In cryptocurrency trading, a strategy may perform well in historical backtests but quickly fail under new market conditions. The problem may not lie in the trading logic itself; the strategy may instead 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 indepe

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?
Rolling backtesting divides historical

What is trade expectancy? Why does it reflect a strategy’s long-term profitability better than win rate alone?
In cryptocurrency trading, a high win rate does not necessarily mean making money, and a low win rate does not necessarily mean losing money. What really matters is how much profit or loss each trade generates on average when you consistently trade by the same rules. That is the core meaning of trade expectancy.
First, what is trade expectancy?
Trade expectancy (EV) is a metric that combines win rate, average profit, and average loss to estimate the long-term average result per trade.

Trading has been really tough this year, and everyone keeps telling me not to focus on just one direction. Sometimes I want to try a different approach and look at stock contracts, but there aren't many markets to choose from, the range of assets is fairly limited, and I have to keep switching platforms.
A couple of days ago, I was chatting with people in a group about stock contracts and took a look at @Gate. I found that it now covers a much wider range of markets and assets than before, so things really have changed.
It now covers six major markets and offers 500+ trading assets. From US st

What are support and resistance levels? Why do these price zones influence traders’ decisions, yet remain far from absolutely reliable boundaries?
In cryptocurrency trading, prices often repeatedly rebound or pull back 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 pressure may increase and a price decline may temporarily slow; a resistance level is a zone where selling pre

Machi Big Brother is making a killing again!
He’s not only going long but also adding to his position, using 25x leverage to build from over 2,000 contracts to nearly 6,700. His latest average entry price is 2366, and his unrealized profit has surged past $460k, but his liquidation price has also been pushed up to 2391.
Big Brother is charging ahead with full confidence, but I’m actually not very bullish on this move in the short term. I recommend positioning for shorts around 2450.
The reasoning is simple:
This rebound after the election results came in looks more like a short squeeze followi

What Is the Relative Strength Index (RSI)? Why Don’t Overbought Conditions Guarantee a Drop, and Oversold Conditions a Rebound?
In cryptocurrency trading, RSI is a common technical analysis indicator that can help traders assess price momentum. But many people immediately short when they see RSI above 70 or rush to buy the dip when it falls below 30, only to find that prices may move in the opposite direction. The issue is that the indicator reflects market conditions, not an inevitable price reversal.
First, what is RSI?
The Relative Strength Index (RSI) typically ranges from 0 to 100 and mea

Gate has officially launched Proof of Security, or PoSEC, extending beyond Proof of Reserves by disclosing the distribution of cold-storage and hot-wallet assets and introducing a cold storage coverage ratio to measure protection under extreme-risk scenarios. Gate’s latest cold storage coverage ratio stands at 104.58%, with 88.26% of assets in cold storage and 11.74% in hot wallets. A coverage ratio of at least 100% means cold-storage assets alone would still be sufficient to cover all user assets even if hot-wallet assets were fully lost. Exchange security is not only about whether reserves are sufficient, but also how assets are stored and protected under extreme conditions. Could cold storage coverage become a new industry standard?[👉 Learn more](https://gate.com/proof-of-security)
