Dump and Pump Detection Test
Description
This test analyzes trading data to detect scenarios characterized by a sudden price decrease (dump) followed by a sharp increase (pump), where users sell at higher prices and subsequently buy at lower prices.
Use Cases
-
Market Manipulation Detection: Identifies instances of coordinated trading activity designed to artificially inflate or deflate asset prices.
-
Investor Protection: Detects manipulation patterns that can harm investors by luring them into buying overvalued assets during a pump or selling undervalued assets during a dump.
-
Regulatory Compliance: Monitors for trading activities that violate financial regulations related to fair market practices, supporting adherence to anti-manipulation laws and preventing fraudulent schemes.

Methodology
- Identify Dump-and-Pump Events
- Identify sharp price declines during the dump window followed by recoveries in the pump window.
- Assign event identifiers, focusing on users with significant sell activity in the dump and buy activity in the pump.
- Aggregate and Compare Trade Metrics
- Calculate total buy and sell volumes, dollar amounts, and profitability.
- Flag users with disproportionate trading activity across events.
- Apply Filtering Criteria
- Filter by ADV, profitability, and buy/sell proportions.
- Highlight users engaging in strategic sell-to-buy transitions.
- Visualize, Report, and Alert
- Generate reports summarizing flagged users with transaction details.
- Provide graphical representations of price movements and trading patterns.
