Why Can a Strategy Perform Well in Backtests Yet Continuously Lose Money in Live Trading?

A trading strategy may have a high win rate in backtests, a consistently rising equity curve, and a seemingly acceptable maximum drawdown.

But once it is put into the market, the results can be completely different: trading costs keep adding up, actual execution prices deviate from expectations, and several trades in a row lose money. The once-impressive equity curve gradually loses credibility.

Where exactly does the problem lie?

Why can’t exchange liquidation data be used directly as a signal to buy the dip?
When Bitcoin suddenly drops sharply and exchange liquidation data surges, many traders think: So many people have already been forcibly liquidated—is the market nearing a bottom?
But in reality, an increase in liquidation volume does not mean the decline is over.
First, we need to understand what liquidation data means. Liquidations reflect cases where some leveraged traders are forcibly closed out by trading platforms due to insufficient margin. They can show the extent of risk being released in the market over a

Many contract traders have had this experience: they correctly predict the market’s overall direction, only to have their positions suddenly liquidated because of a brief, sharp price move.

Why does this happen?

First, excessive leverage is the most common cause. The higher the leverage, the greater the impact of price fluctuations on margin. Even a brief move in the opposite direction can quickly trigger liquidation.

Second, market liquidity affects execution prices. When a large number of sell or buy orders suddenly hit the market, the order book can thin out quickly, making price movemen

Why Does Trading More Frequently Make It Easier to Underestimate the Impact of Costs on Long-Term Returns?

When reviewing their trades, many traders focus only on entry prices, exit prices, and profit or loss, while overlooking a factor that continuously affects account performance: trading costs.

The cost of a single trade may seem small, but as the number of trades increases, these costs can gradually eat into an already limited profit margin.

$BTW I took a 32,000 loss cutting my position last week, and today I finally made it back. Don’t rush to chase—look at the data first: the current price is 1.1768, up 17.55% in 24h, but it surged to a high of 1.3526 before getting dumped back to 0.9483. The range exceeded 40%, and the 73.2M trading volume shows intense turnover—a classic sentiment-driven market, not a trend.
My plan: don’t chase at the current price. Wait for a pullback to the 1.05–1.10 range and buy in batches, keeping the position below 15% of total funds and entering in three tranches. Set a stop-loss below 0.94; if it brea

#OpenAI第三季度营收升至100亿美元

OpenAI has reached another major milestone in the global artificial intelligence industry, with its third-quarter 2026 revenue climbing to approximately $10 billion. This represents nearly 50% growth compared with the previous quarter and almost three times the revenue recorded during the same period last year. The latest figures highlight the rapidly increasing commercial demand for artificial intelligence products and demonstrate how quickly AI is becoming an important part of the global technology economy.

The achievement is particularly significant because OpenAI is

Don’t just focus on Polymarket! The real big opportunity may lie in prediction market infrastructure!

Whenever a new sector takes off, everyone’s first reaction is to look for the next leader. Prediction markets are no exception, and Polymarket naturally attracts the spotlight.
But focusing only on trading platforms could mean missing an even bigger opportunity.
A mature prediction market ecosystem needs more than just a trading interface. It also needs oracles, data indexing, liquidity provision, risk management, identity verification, compliance services, and cross-platform settlement.

OpenAI revenue surges 50%! Has the AI industry finally moved from a spending race to a profit race?

OpenAI’s third-quarter revenue rose to about $10 billion, up nearly 50% quarter over quarter. The figure has energized the entire AI industry once again.
But what’s more noteworthy than revenue growth is that enterprise business is becoming a major driver.
In the past, AI companies loved to tell stories: how powerful their models were, how many parameters they had, and how advanced their reasoning capabilities were. After hearing all that, investors usually had just one question: When will they

Consecutive losses are when many futures traders are most likely to lose confidence.

Some people start doubting their trading system after two or three losses; after a losing streak, others rush to adjust their indicators and change their entry conditions, or even keep increasing their position sizes in the hope of quickly making back their losses.

But the question is: Do consecutive losses really mean a strategy has stopped working?

Not necessarily. To determine whether a trading strategy has stopped working, you need to consider at least five factors.

First, review your trade sample. Thr

In cryptocurrency trading, many people spend a lot of time studying candlestick charts, indicators, and trading strategies, yet overlook a harder problem: their own emotions.

Why do some traders have decent trading systems but still keep losing money in the end? Often, the problem isn’t the market, but emotions interfering with execution.

First, FOMO (fear of missing out). Seeing BTC suddenly rise, they fear missing an opportunity and chase the price regardless of its level, only to see a pullback right after entering.

Second, greed. They’ve already reached their take-profit target, but bec

After the 87395 high, a structural pullback is putting key support to the test.

This is not a place to blindly chase shorts, but an area worth watching closely for a shift in the balance between bulls and bears.

If it holds, watch for a rebound; if it decisively breaks, respect the trend.

Don’t predict the market; just execute the trading logic.

Bitcoin continues to show weakness as sellers maintain control.
The market structure remains bearish, with lower highs and lower lows still intact. The recent breakdown below $76K adds further pressure.
Key levels to watch:
• $72K–$73K: Immediate support
• $76K: First resistance and recovery level
• $78K: Next major resistance
A reclaim of $76K would be the first sign of strength. Until then, I remain cautious about calling a bottom.
Let the price action confirm the next move.

Meanwhile, here in China, Zhu Shunsui was actually given a queue hairstyle
Zhu Shunsui (1600–1682) was a scholar and anti-Qing loyalist during the late Ming and early Qing dynasties. His name was Zhiyu, his courtesy name was Luyu, and his art name was Shunshui. He was from Yuyao, Zhejiang.
After the Ming dynasty fell, he refused to submit to the Qing. He traveled to Japan, Vietnam, and elsewhere, seeking opportunities to resist the Qing and restore the Ming

Does a Breakout Above Resistance Mean the Market Is About to Take Off?

In cryptocurrency trading, many people have experienced this:

The price finally breaks through a key resistance level, and trading volume also increases. Traders think the market is about to take off and jump in, only for the price to suddenly reverse and fall back into its previous range.

This is what traders often call a “false breakout.”

What really needs to be determined is not just whether the price has broken through, but whether the market can continue to accept higher prices afterward.
