How Perpetual Exchange Design Shapes Crypto Trader Behavior

Summary

The paper compares trader behavior on centralized and decentralized exchanges for Bitcoin perpetual futures, organizing exchanges into three architectural models. It examines trading volume, open interest, liquidations, leverage, and price volatility. For decentralized venues using virtual automated market making, the reported relationship between open interest differs for long and short positions. On oracle-priced exchanges, traders tend to act as price takers, responding to movements in the underlying asset.

The study also reports that less informed traders tend to react strongly to positive news by increasing long positions. These results offer evidence about how exchange mechanics and information may relate to trading behavior in digital asset markets. The document does not name all three models or provide sample periods, data sources, or quantitative estimates, so the findings cannot be assessed for statistical strength or assumed to apply uniformly across exchanges and market conditions.

Key ideas

• The paper compares trader behavior across centralized and decentralized perpetual futures exchanges.
• It groups exchange architectures into three models and examines volume, open interest, liquidations, and leverage.
• On virtual automated market making exchanges, open interest has different reported effects for long and short positions.
• Traders on oracle-priced venues tend to respond to underlying price movements as price takers.
• Less informed traders are reported to increase long positions after positive news.

In this paper, we analyze traders' behavior within both centralized exchanges (CEXs) and decentralized exchanges (DEXs), focusing on the volatility of Bitcoin prices and the trading activity of investors engaged in perpetual future contracts. We categorize the architecture of perpetual future exchanges into three distinct models, each exhibiting unique patterns of trader behavior in relation to trading volume, open interest, liquidation, and leverage. Our detailed examination of DEXs, especially those utilizing the Virtual Automated Market Making (VAMM) Model, uncovers a differential impact of open interest on long versus short positions. In exchanges which operate under the Oracle Pricing Model, we find that traders primarily act as price takers, with their trading actions reflecting direct responses to price movements of the underlying assets. Furthermore, our research highlights a significant propensity among less informed traders to overreact to positive news, as demonstrated by an increase in long positions. This study contributes to the understanding of market dynamics in digital asset exchanges, offering insights into the behavioral finance for future innovation of decentralized finance.
