What Is Rolling Backtesting? Why Is One Out-of-Sample Test Still Not Enough to Prove a Strategy Is Reliable?

Passing a single out-of-sample test does not mean a trading strategy will remain effective in all market conditions. A particular period may happen to favor the strategy, so we also need rolling backtesting to observe its performance across different time periods.

First, what is rolling backtesting?

Rolling backtesting involves repeatedly using past data, in chronological order, to develop or optimize a strategy, then testing its performance on a subsequent period of data that was no

$BTC has fallen back below 70k for the first time since August 20; U.S. PPI is also due at 21:30 tonight.
It's down more than 6% in 24 hours, now around 68.7k, and $ETH has also fallen to around 1,930.
The last time it was below 70k was in mid-August, when it fell as low as 62.8k.
This isn't the time to add leverage ahead of PPI; if it can't reclaim 70k, there's no need to rush into buying the dip.

Why Can Trading Strategies That Perform Well in Backtests Fail in Live Markets?

A trading strategy may deliver substantial returns and a high win rate in historical backtests, while even keeping its maximum drawdown under control, yet produce very different results once deployed in the market. The problem may not necessarily lie with the strategy itself; it may also stem from the gap between backtesting and live trading.

First, historical data does not represent the future. Backtesting can only assess a strategy’s performance in specific historical market conditions. Market structure, volati

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

Price, open interest, and funding rates are all rising—is the market overheated?

When crypto markets continue to rise, if price, open interest (OI), and funding rates climb at the same time, many traders believe the move is accelerating, while others worry that longs are becoming overcrowded and the market may be about to reverse.

But the simultaneous rise in these three indicators does not directly lead to the conclusion that the market is about to peak. What truly matters is what each of them reflects, and whether they form a combination that warrants concern.

First, rising prices reflect

Why Can Spot-Futures Arbitrage Still Lose Money in Practice, Even Though It Seems Like a Sure Bet?

When Bitcoin futures prices are significantly higher than spot prices, a common strategy is to buy spot while selling futures, then wait for the price gap to narrow and profit from it.

This strategy is commonly known as cash-and-carry arbitrage. It has a clear pricing rationale, but that does not mean it is risk-free.

First, the price gap is not the same as the final profit.

Suppose an asset has a spot price of 100,000 USDT and a futures price of 102,000 USDT. The apparent price gap is 2,000

$ZEC Yesterday, the price declined steadily from the open. After a second bottom test on the higher timeframe broke below the 720 level, it stopped at 71218.1. A slight rebound near 720 was followed by sideways consolidation. The higher-timeframe downtrend remains unchanged, and upside is limited, so I chose to enter at 71709.8, with a stop-loss at 725. This morning, the price continued to decline, with several fakeouts to the upside but no reversal signal. Higher-timeframe support is at 678/6

There’s a shitcoin with trading volume lower than the trash in a garbage can. It’s always saying that other coins have fallen so much from their all-time highs that they’re worse off than us, so our coin is retail investors’ chance to turn things around.

The truth is, those coins are still alive. Has your coin ever been alive? So love yourself and don’t buy shitcoins.
