What Is the F1 Score? How Can It Combine Precision and Recall to Evaluate a Trading Model?

In crypto quantitative trading, one model may issue very few bullish signals, resulting in high precision but missing many upward opportunities; another may identify most market rallies but generate many false signals. It is difficult to evaluate a model comprehensively by looking at just one metric. The F1 score is a way to jointly measure precision and recall.

First, what is the F1 score?

The F1 score is the harmonic mean of precision and recall, calculated as: F1 = 2 × precision × recall ÷ (precisi

XRP clings to its previous low in weak sideways trading; moving-average resistance remains to be broken

Currently at 1.0833 (-1.55%); after consecutive declines from 1.3414 to a low of 1.0764, it has moved sideways. The 4H moving averages are bearishly aligned (EMA7:1.0970/EMA20:1.1288/EMA60:1.1922), with the price below EMA7. A rebound needs to reclaim 1.097 to show signs of stabilization; only a break above 1.1288 would signal strengthening.

Scenario: If 1.0764 holds → a low-volume rebound to 1.097; above that, watch 1.1288. If it fails → a wick down to 1.0650 followed by a

What Is Walk-Forward Testing? Why Can Backtesting Over a Fixed Period Hide Strategy Flaws?

In cryptocurrency trading, market conditions are constantly changing. A strategy may perform exceptionally well in a bull market but get stopped out frequently in a sideways market; it may also be profitable on a certain period of historical data but fail to adapt to subsequent volatility. Walk-forward testing can help traders assess how well a strategy adapts across different periods.

First, what is walk-forward testing?

Walk-forward testing typically divides historical data into consecutive time win

Expectations of Fed rate hikes have largely been priced in. Gold has broken below the lower boundary of the ascending channel on a short-term basis, reaching around 4090. As I said earlier, the 4080–4100 range is a support zone. If support in this range holds, expectations for this phase have already been priced in ahead of time; this was just a bout of emotional selling. If prices stabilize, they should still rebound. Pay close attention to the strength of support around 4080. If it holds, that will give us an opportunity to go long$XAU $XAUT

What Is Survivorship Bias? Why Can Studying Only Coins That Still Exist Today Overestimate a Strategy’s Returns?

In the cryptocurrency market, some traders select currently popular and actively traded coins for historical backtests, then use the results to judge whether a strategy works. But if they ignore projects that have been delisted, lost liquidity over time, or performed very poorly, the backtest results may be systematically biased. This phenomenon is known as survivorship bias.

First, what is survivorship bias?

It refers to focusing only on objects that still exist or have succeede

Trump Media Reports $409.7M Q3 Profit, Driven by Digital Assets

Trump Media & Technology Group reported a net profit of $409.7 million for the third quarter of 2026, with digital asset gains playing a major role.

The company recorded approximately $378.1 million in digital asset gains, highlighting how crypto holdings can significantly influence corporate financial results.

This shows the growing impact of digital assets on corporate balance sheets, but also th

NVDA Under Pressure: Congressional Testimony Request and Technical Breakdown

While the broader semiconductor sector attempted to recover, Nvidia ($NVDA) continues to face significant selling pressure.

Today's early-session BTC rebound-short setup has played out in the expected direction.
After rebounding, the price failed to break higher and sustain the move. Overhead resistance held firm, and the price gradually pulled back, in line with the early-session forecast of a rebound facing resistance and turning lower. Although it has yet to fully reach the downside target, the move of the rebound meeting resistance and pulling back has already unfolded, confirming the early-session assessment. The market remains choppy, so risk management should remain a priority. Continue to watch how support
