What Is Model Calibration? Why Doesn’t a 70% Probability of a Price Increase Mean the Price Will Definitely Rise?

In cryptocurrency quantitative trading, a machine learning model may predict a 70% probability that BTC will rise in the next period. But this does not mean the price will definitely rise, nor does it mean the model actually has 70% predictive accuracy. To understand whether probability forecasts are trustworthy, it is important to understand model calibration (Probability Calibration).

First, what is model calibration?

Model calibration focuses on whether predicted probabilitie

What Is Data Leakage? How Is It Different from Look-Ahead Bias, and How Can You Avoid Misjudging Machine Learning Trading Models?

In crypto quantitative trading, machine learning models may achieve very high accuracy on a test set but perform poorly once deployed in real trading. Sometimes the problem is not that the model is insufficiently complex, but that data leakage occurred during training and evaluation, allowing the model to indirectly access information it should not have known.

First, what is data leakage?

Data leakage occurs when information that should not be available for the c

A 5% jump does not, by itself, constitute a trend.

The sharp rise in the KOSPI, which exceeded 5%, was driven primarily by Samsung and SK Hynix. From the perspective of an individual investor, I do not view this move as the beginning of a trend.

Data flows originating from the U.S. and various geopolitical developments remain unclear. In the current climate, it is wiser to maintain a cautious approach and wait for the markets to settle. On days like these, the costliest mistake one can make is to increase one’s position out of fear of missing out on a single day’s rally. While this surge o

What Is the Brier Score? How Can the Quality of a Trading Model’s Probability Forecasts Be Evaluated Mathematically?

In cryptocurrency quantitative trading, even a model that often correctly predicts the direction of price movements does not necessarily provide reliable probabilities. For example, if a model predicts a 90% probability that BTC will rise, but the price rises only 60% of the time in similar cases, it may be overconfident. The Brier score can help us evaluate the error between probability forecasts and actual outcomes.

AMEC has launched its Primo Matrix plasma wafer dicing equipment and completed its first delivery to a major domestic integrated circuit packaging customer. The equipment is designed for high precision, low damage, and narrow dicing streets, with a minimum street width of 5 micrometers to reduce wafer area loss.

When people talk about advanced packaging, they tend to focus on big concepts like stacking and interconnects. But what really drives yield is the painstaking work of narrowing wafer dicing streets to 5 micrometers. Every bit of material saved at the edges counts.

$SNXXB$SNXXB Current conclusion: Short-term bias is bullish, but do not chase the price higher. Volatility is elevated, so position size must be cut to less than half the usual level. Rationale: The current price of 3.74 is already near the upper Bollinger Band at 3.79432, and the 30-candle range is 23.53%, a typical high-volatility setup. MA5=3.694 is slightly above MA20=3.6905, so the trend remains intact, but bullish momentum is weakening at the margin. The MACD histogram at -0.009444 has turned bearish, RSI=62.3 is nearing overbought territory, and the Fear and Greed Index at 32 is in the

Yesterday, we made a short-term long trade on Bitcoin and came away with a decent gain. Unfortunately, it failed to break out and develop into a bigger trend. We have now exited the position entirely and taken profits.
Honestly, this move has been pretty interesting. When I checked the market this morning, I felt there was potential. Bitcoin had been hovering around a key level for a while, and volume was gradually picking up, so I decisively entered a short-term long position in the afternoon. The rally in the evening was strong, and it felt good to see the unrealized gains on the books. But

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

Cathie Wood was buying while everyone else was capitulating again. She spent 45.9 million buying Nvidia at Thursday’s lows, then kept adding on Friday. That’s just how she is: the more it drops, the more willing she is to buy. She’s betting on computing power three to five years from now, not this week’s chart. Whether you follow her is another matter, but putting real money on the line beats just calling the bottom. Are you still holding NVDA?

Ondo Falls Below All 3 Daily EMAs as Selling Pressure Intensifies
ONDO remains tilted toward a downtrend.
As of November 9, ONDO is trading around $0.352, with the price still sitting below all three key daily EMAs. Specifically, the EMA20 is around $0.4009, the EMA50 is at $0.4186, and the EMA200 is near $0.3866. This indicates that the medium-term structure remains weak, even though the price is showing signs of slight stabilization on shorter timeframes.

$XRP ‌
The market structure has clearly shifted from a bullish rally to a corrective bearish phase. After peaking near 1.1697, the price aggressively broke down, forming a steep descending channel. The structure is currently characterized by lower highs and lower lows, but we are seeing a potential stabilization attempt near the 1.0765 support level.

The K-lines show a strong initial sell-off followed by a period of consolidation. Price action is currently hugging the lower Bollinger Band (LB: 1.0861), indicating persistent selling pressure, though the band is beginning to flatten. The movi

$NVDA This coin is being driven by a major piece of gossip today—Huang's private life was dug up, Trump stepped in to smooth things over and tossed out “ignorance is no crime,” bringing Nvidia into it along the way. It’s a wild story, but traders only care about one thing: who’s going to foot the bill.

The real issue isn’t the gossip; it’s interest rates and liquidity. The AI trade runs on liquidity, and when the taps tighten, even the best story has to be paid for in installments. Tonight’s data hurdle hasn’t been cleared yet; anyone betting on a direction is buying lottery tickets early, a
