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

Market Analysis: VVV/USDT Intraday Technical Update

Reviewing the 30-minute chart, the immediate short-term bias remains corrective. The price action is currently compressing beneath the primary moving averages. Specifically, the MA

Many people see a funding rate of 0 and assume that neither longs nor shorts are taking a side. In fact, a zero rate means the perpetual price is tracking spot, with both sides waiting for the other to move first. $RAY is in exactly this state now.
The current price is 1.7771, up 9.70% in 24 hours, but the funding rate is +0.0000%, indicating that this rally is not being driven by leveraged longs in futures. FOMO buying isn't extreme, which leaves room for further upside. On the moving average front, MA5=1.77104 is above MA20=1.75418, with the short-term average supporting the price; RSI=61.2

Yesterday's market move was just the latest opportunity!
Keep risk management ingrained in your bones, and leave the rest to the market. Once the wind picks up, doubling your account in a few days comes naturally.
BTC: positioned near 76000, and it has now reached a high of 81188. ETH: went long near 2230, reaching a high of 2450.
Calling out levels in advance and having the courage to act when the market moves—that's the value of trading.
I've always believed that the biggest market moves are never captured by chasing them, but by anticipating them, waiting patiently, and acting decisively.

$ETH Still wondering whether to buy? The direction is already clear: a drop back to the former resistance level at 2388 is the dividing line. If buyers hold it, the price could head for 2547; if they don’t, don’t try to catch a falling knife. Among similar public blockchains, its chart structure is the cleanest this time around. While others are still building a bottom, it has already broken out of its descending channel. During the sideways stretch before the halving $BTC , capital tended to flow into assets with this kind of clear-cut rhythm. Decide for yourself whether to get in—don’t wait

Apparently, Micron scrapped plans for another fab in Taiwan because its union there was asking for too much in bonuses lol.
The fab was supposed to come online in 2028.
So that’s less supply hitting the market in 2028.

Come to think of it, I just reposted Feng Ge’s $XAU trade 3 days ago (11-02), and here it comes again 😅
I’m just here to relay the signals. Whether to follow and how much to put in is up to you. The market can go crazy, but risk management mustn’t.

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)
