Why can a strategy with a high backtest win rate still lose money continuously in live trading?

Have you ever seen a trading strategy like this?

Its backtest win rate reaches 70%, and its equity curve keeps rising. Its parameters have been optimized repeatedly, and its historical performance looks quite impressive.

But once it goes live, the account starts slowly bleeding.

Some think market conditions have changed, others think the parameters still aren’t good enough, and some start looking for new indicators.

But before changing the strategy, there is a more important question:

Does you

How can you tell whether a trading strategy has a genuine statistical edge rather than making money by chance?

One of the easiest ways to misjudge things in the trading market is to treat making money as proof that a strategy works.

A string of winning trades could mean the strategy has an edge, or it could simply mean the market happened to be favorable to it.

So how can you tell the difference?

The key is not how much a few trades made, but whether the strategy has a repeatable positive expectancy after costs under sufficiently reasonable testing conditions.

I. First, understand what a

Anthropic is a mirror reflecting the element of “choice” in OpenAI’s losses

Looking only at OpenAI’s losses, it’s easy to conclude that “model companies just burn money.” But Anthropic’s Q3 figures call that conclusion into question.

Anthropic’s Q3 revenue was nearly $17 billion, up 47% quarter over quarter and 70% higher than OpenAI’s; its operating loss was only $567 million, mainly due to short-term compute purchases and a one-time $2 billion employee charitable matching contribution. OpenAI lost $10.9 billion in the same period. The revenue gap was 70%, while the loss gap was nearly 20-f

How Is Cryptocurrency Regulation Changing, and What Does It Mean for Everyday Users?

In the Web3 world, many people follow Bitcoin prices, market trends, and new projects, but may overlook an important factor affecting the entire industry: changes in regulatory rules.

Regulation is not just a concern for exchanges and project teams. It can also affect everyday users’ account verification, asset custody, stablecoin use, cross-border transfers, and access to products and services.

But regulatory changes cannot simply be viewed as bullish or bearish.

What really matters is what the rules chan

Google uses Veo to fill gaps in Esther Mahlangu’s memories from before 1980
Google Arts & Culture launched the first online retrospective of South African artist Dr. Esther Mahlangu to mark her 91st birthday. Curator Dr. Nontobeko Ntombela writes that the collection contains almost nothing about her life before 1980, so the team accordingly used memories narrated by Mahlangu herself to generate still images, then turned them into videos with Veo, filling the gap between her starting to paint at age 10 and her first documented works.

When prices rise, what you wait for is time; when they fall, it’s space. Ethereum is trading sideways today, and when the direction is unclear, it’s best to wait patiently.

Why might changing your trading rules after a string of losses be more dangerous than the losses themselves?

Many traders don’t lose to the market. Instead, after a string of losses, they gradually abandon the trading discipline that originally worked.

First loss: They think it was just bad luck.

Second loss: They start doubting the strategy.

Third loss: They change their stop-loss, adjust parameters, and increase their position size.

Fourth loss: They completely overturn their original trading system.

Here’s the question: Are you optimizing your strategy, or trying to escape the discomf

$AGT The bulls have really built momentum this time, with trading volume surging and price breaking through the range it had been stuck in for so long. The upward momentum is clearly strong. But don't get carried away after a sharp rally; consider the risk of a pullback before chasing the price higher.

Plan: Entry range $0.0540–$0.0570, first target $0.0600, second target $0.0630, third target $0.0680, with a stop at $0.0500.
Also keep an eye on the price action of $INIT and TRUMP.
