What Is Backtest Overfitting? Why Can a Strategy With Perfect Historical Performance Fail Completely in Live Trading?
In cryptocurrency trading, some people keep adjusting indicator parameters, take-profit and stop-loss levels, and entry conditions until the strategy achieves the highest possible returns in historical backtests. But better historical performance does not necessarily mean a more reliable strategy. Overfitting to historical data may instead make a strategy less capable of adapting to future markets.
First, what is backtest overfitting?
Backtest overfitting occurs when a strategy

What Is SHAP? How Can You Explain Why a Machine Learning Model Makes a Bullish or Bearish Prediction?
In crypto quantitative trading, machine learning models may use features such as price momentum, trading volume, volatility, and funding rates to predict future trends. But when a model gives a bullish or bearish result, that doesn’t mean traders know why it made that judgment. SHAP is a method for helping explain model predictions by analyzing how different features contribute to an individual prediction.
First, what is SHAP?
SHAP is based on the idea of Shapley values, allocating changes in

The original plan is still valid!!!

The same 1000U can have completely different outcomes. $DUSK Today’s -17.36% move is a textbook lesson. The current price is 0.0956, down from a 24h high of 0.1190 to a low of 0.0950, with 6.9M in trading volume—this isn’t a pullback; capital is voting with its feet.
First, look at the market: this morning, people were still calling for a “breakout” above 0.11. Now it’s at 0.0956, with a 25-point intraday range. Anyone who chased the price with 1000U is left with just 826U. What’s the key issue? The low of 0.0950 is right next to the current price, which shows that selling pressure hasn’t ful

$PEPE Strength and Crowding Are Emerging at the Same Time; The First Pullback Will Be the Real Test
The current price of 0.00000499 USDT is like a sheet of paper that has been folded over and over. $PEPE surged from 0.00000471 to 0.00000523 within 24 hours, and behind the +2.89% gain lies a subtler signal: both the 1-hour and 4-hour charts show a bullish stance, but trading participation is only 0.17x. This combination of strength and crowding often tests judgment more than a simple rise or fall.
My view: the trend remains bullish, but whether buyers step in at higher levels matters more than

Mr. Daxiao is a deeply compassionate person. He saw through the true nature of the stock market long ago, and he also shared the solution with ordinary people long ago: “Be a good person, buy good stocks, and reap good rewards.”
For most people, this is the best solution, because the stock market is a zero-sum game—or even a negative-sum game. The greedier you are, the deeper you get in. The less you can bear, the harder it is to get out.
But human nature is what it is, and the stock market is precisely where human nature plays out. He saw through all of this long ago, too.
And yet this old ma

$SOXLB Currently at 97.82, down 5.7% over 24H (96.08–109.11). The 1H structure is weak, with RSI at 35, while the 4H trend is relatively strong, with RSI at 57. In the short term, holding above resistance at 109.11 is needed for a chance at a reversal; a break below support at 96.08 could accelerate the decline to new lows. Watch whether a retest of 109.11 can break through on increased volume—the 4H bullish trend needs 1H confirmation. Market volatility is high; for observation only.

$BTC Price dumped into our bottom pivot window (28-30th),
It didn't went for the sweep of the mFVG (75k) following our last fractal and is now starting to form bottom like structure here,
Considering it, I think we have already got the flush in the last pullback (to 75k),
This is still an idea for now but looking at the time pivot and the current market structure.
It looks like we have formed our purple dot and now it's time to hunt the cluster of liquidity above 88k and form the green dot there.
I am swing long from 80.1k and will be adding some alts if we get any pullback (SOL, ETH, HYPE)
