Pair trading has become a staple strategy for navigating volatile crypto markets. While it may sound simple—long one asset, short another—the success of this approach often hinges on selecting the correct leg to short. The goal of the short leg is to hedge the market risk while amplifying the relative outperformance of the long leg. In this article, we explore how to select the short leg, why it matters, and how to utilize a data-driven approach for success.
Why Choosing the Short Leg Matters
At the core of pair trading is the desire to exploit the relative movement between two assets. Ideally, the long asset should outperform, while the short asset either declines or remains neutral. This creates profit on both sides: gains on the long leg and losses (or minimal gains) on the short leg. The wrong short leg can negate the gains of the long leg, which is why careful selection is crucial.
For instance, in a typical Bitcoin (BTC) and Worldcoin (WLD) pair, if BTC rallies significantly while WLD stays flat or falls, the trader can capitalize on the BTC outperformance while minimizing overall market risk. However, if WLD suddenly outperforms BTC due to unforeseen events, the trade may underperform or even result in losses.
Data-Driven Criteria for Selecting the Short Leg
The choice of the short leg involves balancing several factors, all of which can be informed by data:
1. Correlation and Volatility
Pair trading relies on a certain level of correlation between the two assets. Highly correlated pairs tend to move together, which minimizes the risk of one leg significantly diverging from the other. For example, in high-frequency data, correlations between major blue-chip cryptos like BTC and ETH can exceed 90%. Ideally, the short leg should have a high correlation but exhibit greater downside volatility.
Data Tip: Look at historical correlation and volatility metrics over different time frames (e.g., daily, weekly, and monthly). This can be easily observed using pair charts, like ETH/BTC, to visualize how one asset performs relative to the other during different market conditions, as well as more sophisticated tools like Crypto Wizards.


2. Liquidity Considerations
The short leg should be liquid enough to handle large trades without significant slippage. Illiquid assets can be risky to short as sudden spikes in trading volume or market-moving news can drive sharp upward price movements.

Data Tip: Use liquidity metrics, such as order book depth and average daily trading volume, across popular exchanges like Binance (which supports over 250 trading pairs). Filtering the least liquid tokens out of your shortlist for the short leg will reduce the risk of price manipulation or large price movements due to thin order books.
3. Idiosyncratic Risks: Avoid Event-Driven Moves
Before choosing the short leg, it is critical to assess whether there are any upcoming events that could disproportionately affect its price. Regulatory changes, network upgrades, or high-profile partnerships can drive unpredictable volatility.

Data Tip: Keep a close eye on news feeds and calendar events. For example, if there’s a significant development like a protocol upgrade or token burn event, it may not be suitable for a short position. Using platforms that aggregate news and on-chain analytics will help traders avoid getting caught by surprise(Pear Things to Consider).
4. Relative Strength
An asset that shows signs of persistent weakness compared to its pair is often a good candidate for the short leg. This weakness can be gauged through technical indicators such as Relative Strength Index (RSI) or Moving Averages. If the asset is underperforming over multiple time frames, it signals a potential decline.


Data Tip: RSI and moving average crossovers (e.g., 50-day vs. 200-day) provide clear signals of relative weakness. Traders should also monitor whether the short leg has repeatedly failed to break through key resistance levels.
5. Funding Costs and Arbitrage Considerations
In perpetual futures markets, the funding rate is a critical consideration. A positive funding rate (where shorts receive funding and longs pay) can offer an additional layer of profitability. For example, if you are short ETH and the funding rate is positive, you receive a payment for holding the short position, which enhances your return.
Data Tip: Calculate net funding across the selected pair and include this in your decision-making process. Using funding heatmaps available on Binance and other exchanges can help identify pairs where shorting is more cost-effective, especially when the funding rate is positive.

Future Features for Data-Driven Trading on Pear Protocol
As pair trading evolves, so must the tools that support it. Pear Protocol has already established itself as a streamlined platform for executing pair trades, but there are several key features that could further enhance the trading experience and provide users with a more data-driven edge. Here are three features that I, as a trader, would like to see integrated into Pear Protocol in the future:
1. Screener for Long/Short Pair Selection
A robust screener that automatically suggests long and short pairs based on the criteria we've discussed—correlation, volatility, liquidity, and funding rates—would be a game-changer for traders. By integrating data analytics directly into the platform, Pear Protocol can offer traders the ability to quickly identify ideal pairs, removing much of the manual analysis required today. A screener could:
Provide a ranked list of potential pairs based on customizable filters.
Display real-time metrics such as correlation and historical volatility.
Highlight optimal short-leg candidates with favorable funding rates or weaker relative strength.
This feature would empower traders to make quicker, more informed decisions and seamlessly find pairs that fit their trading strategy.
2. Market Overview Page with Emissions and Funding Data
Understanding tokenomics and funding rates is crucial for successful pair trading. A market page that provides real-time data on token emissions, alongside funding rates across popular exchanges, would offer valuable insights to traders looking to short tokens with high emissions or negative funding rates. Such a page could:
Track tokens with low vs. high emissions, helping traders gauge potential supply pressure.
Show funding rates in real-time, allowing traders to capitalize on favorable conditions for short positions.
Include customizable alerts for funding rate changes or emissions announcements.
This would make Pear Protocol a one-stop hub for tokenomics and funding data, increasing its appeal to traders seeking data-driven advantages.
3. Unified Platform for Data and Analytics
The ultimate goal for Pear Protocol should be to become a fully integrated platform that seamlessly blends trading execution with powerful analytics. By consolidating all relevant data—correlations, volatility, liquidity, news events, and funding rates—Pear can become a go-to destination for traders who want not only to execute trades but also to analyze market conditions in real-time. Imagine having a dashboard that:
Displays all the key data points needed for pair trading in one place.
Provides predictive analytics based on past market behavior, helping traders anticipate trends.
Allows for in-depth back-testing of pair trading strategies using historical data.
By evolving into a unified platform for trading and analytics, Pear Protocol can set itself apart from other platforms and attract a broader base of sophisticated traders.
