#Valuescan's historical anomaly list can check the historical anomaly records of any cryptocurrency—what day it made the list, how strong the signal was, when it was removed from the list. The true value of this feature isn't just viewing history, but using historical backtesting to verify your judgment logic.

Three practical methods
1. Signal validity backtest
Choose a coin you've recently traded, check its anomaly history
Compare the signals at each listing with the subsequent price trend
Verify whether your entry rules are truly effective: how much did it rise after double signals appeared? What's the win rate?
How long after signal decay does the price top out?
After being delisted, does it continue to rise or immediately pull back?
Use data to validate intuition, don't rely on feelings to make decisions
2. Recognizing "habitual" coins' patterns
Some coins repeatedly make the list and drop off, with similar trends each time
Backtracking history reveals their rhythm: peak within 2 days after listing → quick in and out
If listed for more than 5 days → can hold a bit longer
Interval between listings <48 hours → high continuity, worth tracking
Every coin has its own "personality," and history is the best personality test
3. Calibrating confidence in current signals
For a coin currently listed, first check its historical listing success rate
Historically, 3 listings with 2 big surges → high confidence, can hold a heavy position
Historically, 5 listings with 4 false breakouts → low confidence, try a light position
The same signal can have completely different significance across different coins
Lesson: trading without looking at history is like driving blind; backtracking history is like looking at a map in advance.
