What Is Overfitting? Why Can More Finely 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 live markets, their performance can quickly deteriorate. A common reason behind this is overfitting.
First, what is overfitting?
Overfitting occurs when a strategy adapts too closely to specific fluctuations and chance patterns in historical data, leading it to perform well in the past but lack the ability to adapt to

$DASH$DASH is currently at 48.69, 24h +4.80%. MA5=49.014 remains above MA20=48.486, but the price has pulled back below the moving average. RSI=55.6 is neutral to slightly bullish; the MACD histogram=-0.07846 signals weakening short-term momentum. The Bollinger range is 46.8345–50.1375. The funding rate of +0.0100% indicates that long positions are slightly crowded, while the Fear & Greed Index at 50 is neutral. Assessment: This is a pullback within an uptrend, not a trend reversal—the price remains above MA20, RSI has not fallen below 50, and the Bollinger midline has held, indicating a healt

Explosive! A whale is down 3.37 million, and $SNDK 's market makers are ready to “slaughter the pigs”!
As long as the longs are still alive, the shorts won't stop; trying to catch the bottom halfway down is just handing them your head!
Folks, look at the on-chain news: a whale bought the dip at an average price of 1115. With the price now at 1013, they're down 3.37 million in half a day! Combined with accelerating capital outflows and bearish whales raking in profits, the market makers' intentions are now crystal clear: fake rally to lure in longs, then dump for real and liquidate them!

Tomorrow’s jobs report might be the most “good news is complicated” data point of the month. A few days ago I would have said strong jobs equals bullish. In this market, I’m not sure that’s true anymore.
1. Why a strong number isn’t automatically good
The Fed held rates at 3.75% to 4.00% on Oct 28, but the conversation isn’t about cuts. It’s about whether another hike comes in December, and futures are pricing that at roughly 80%. The 10-year yield is sitting near 4.9%. So the data isn’t judged by “is the economy fine?” It’s ju

Does a high win rate mean a strategy is excellent? Why does profitability also depend on the risk-reward ratio?
In cryptocurrency trading, many people treat a high win rate as proof of strong trading skills, but frequent wins do not mean long-term profits. If each win is small but a single loss is huge, an account can still steadily shrink even with a high win rate. What really matters is the combined result of the win rate, risk-reward ratio, and trading costs.
First, what are the win rate and risk-reward ratio?
The win rate is the proportion of profitable trades out of all trades. The risk-r

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 but quickly fail in new market conditions. The problem may not lie in the trading logic itself; the strategy may instead be overfit to the historical data used for optimization. Out-of-sample testing is an important method for identifying this problem.
First, what is out-of-sample testing?
Out-of-sample testing means independently evaluating a strategy using data that was not used in its development or para

What is leverage? Why does higher leverage often mean less room for error?
In cryptocurrency trading, leverage allows traders to control larger positions with less margin, but it does not make market risk disappear. On the contrary, the higher the leverage, the greater the impact that a price move of the same magnitude usually has on margin.
First, what is leverage?
Leverage is a way to control a larger trading position using margin. For example, ignoring other factors, 10x leverage lets you open a notional position of about 1,000 USDT with 100 USDT of margin. But this does not mean your actua

The blockchain doesn't automatically know BTC's real-time price. So what do DeFi lending protocols use to determine collateral value?
The answer: oracles. 🔗
They provide external data to smart contracts, but their data sources, update delays, and mechanisms for handling anomalies can all affect protocol security.
Before participating in DeFi, don't just look at yields. Also ask:
🔹 Where does the price data come from?
🔹 How are data anomalies handled?
🔹 Do multiple protocols rely on the same data source?
🔹 How will liquidation mechanisms operate during extreme market conditions?

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)
