The title speaks for itself. When developing strategies, especially for smaller accounts, sometimes I just talk it out with AI. With the current trend I've been noticing with crypto and the derivates market I thought it would be interesting to get a roast session on why this strategy is trash. please feel free to go ahead
"Crypto Statistical Arbitrage
A Simple Guide to Pairs Trading in Crypto
January 2026
1. What Is Statistical Arbitrage?
Statistical arbitrage (or "stat arb") is a trading strategy that profits from temporary price differences between related assets. Instead of betting on whether crypto goes up or down, you bet on the
relationship between two assets returning to normal.
Think of it like this: If two things usually move together and suddenly one jumps ahead while the other lags behind, eventually they tend to meet back in the middle.
2. The Core Idea: A Simple Analogy
Imagine two street vendors who both sell rain gear. One sells umbrellas, the other sells raincoats. When it rains, both see their sales go up together. Their businesses are correlated.
Now imagine one day the umbrella vendor has a viral TikTok and sales spike, but raincoat sales stay normal. What do you do?
Option A: Bet umbrella sales will fall back to normal
Option B: Bet raincoat sales will catch up
Option C: Do BOTH at once (this is stat arb!)
By betting on both sides, you don't care which one happens — you just need the relationship to normalize.
3. How It Works With Crypto
Step 1: Find Related Pairs
Many cryptocurrencies move together. When BTC goes up, most altcoins follow. We look for pairs that have a stable relationship over time.
Step 2: Wait for the Spread to Get "Weird"
We measure how far apart the two assets are from their normal relationship using something called a Z-score. This is just a fancy way of measuring "how many standard deviations from normal."
Z-score = 0: Normal relationship
Z-score = +2: One asset is unusually expensive relative to the other
Z-score = -2: One asset is unusually cheap relative to the other
Step 3: Trade When Z-score Hits ±2
When the Z-score gets extreme (typically beyond ±2), we enter a trade:
If Z = +2: Short the expensive one, Long the cheap one
If Z = -2: Long the expensive one, Short the cheap one
Step 4: Exit When Z-score Returns to 0
When the relationship normalizes (Z-score crosses 0), we close both positions. We've captured the "mean reversion."
4. Understanding Crypto Derivatives Beta
Why do all crypto charts look the same? If you've ever noticed that BTC, ETH, ADA, SOL, and XRP charts look nearly identical, you're seeing beta in action.
What Is Beta?
Beta measures how much an asset moves relative to a benchmark. In crypto, we use BTC as the benchmark (beta = 1.0). If an altcoin has beta = 2.0, it means when BTC moves 1%, that altcoin typically moves 2%.
Crypto Beta Values (Empirical)
Based on actual market data, here are the beta values for major cryptocurrencies relative to BTC:
Asset
Beta to BTC
When BTC Moves +1%
BTC
1.00x
BTC moves +1.00% (baseline)
ETH
1.98x
ETH moves +1.98% (nearly 2x)
ADA
2.20x
ADA moves +2.20% (highest beta)
XRP
1.77x
XRP moves +1.77%
SOL
1.55x
SOL moves +1.55%
What This Means for Stat Arb
When BTC moves 3%, here's what we'd expect each asset to move:
ETH: +5.94% (3% × 1.98)
ADA: +6.60% (3% × 2.20)
XRP: +5.31% (3% × 1.77)
SOL: +4.65% (3% × 1.55)
If ADA only moves +4% instead of the expected +6.6%, that's a deviation from beta — exactly what stat arb looks for.
Effective Multiplier (Leverage × Beta)
When trading crypto derivatives with leverage, the real "bang for your buck" is leverage × beta. This is the effective multiplier:

Insights: Despite ADA having the highest beta (2.20x), it only has 5x leverage, so ETH with 10x leverage and 1.98x beta is actually the most capital-efficient asset for derivatives trading.
Why ADA/XRP makes a good pair: Both are high-beta altcoins (2.20x and 1.77x) with similar investor profiles. When one spikes on retail FOMO, the other tends to catch up. This creates tradeable mean-reversion opportunities.
5. Why Trade Both Sides?
This is the magic of stat arb: You don't care if crypto goes up or down.
Long one asset (betting it goes up)
Short the other (betting it goes down)
If the whole market drops 10%, both positions lose value — but one goes up relative to the other. Your profit comes from the relationship changing, not the overall direction.
This is called being "market neutral" — you've hedged out the market risk and are only betting on the spread.

8. Why Win Rate Doesn't Matter
Most people obsess over win rate. "I want a strategy that wins 80% of the time!" But win rate alone is meaningless. What matters is expectancy.
The Expectancy Formula
Expectancy = (Win Rate × Average Win) - (Loss Rate × Average Loss)
A Counter-Intuitive Example
Imagine a strategy with only 10% win rate. Sounds terrible, right? Let's see:
100 trades total
90 losers at -$1 each = -$90
10 winners at +$100 each = +$1,000
Total P/L: +$910 despite 90% of trades losing!
Expectancy per trade: (0.10 × $100) - (0.90 × $1) = $10 - $0.90 = +$9.10
Most people wouldn't trade this because "90% of trades lose!" But it's a winning system.
9. Why ADA/XRP Works (The Explainability Test)
Having good backtest numbers isn't enough. You need to be able to explain WHY the edge exists. Otherwise it might just be luck (curve fitting).
For ADA/XRP, we can explain the edge:
Same investor base: Both are retail-favorite "hope coins" bought by similar traders
Similar risk profile: Both are speculative altcoins with high volatility
Liquidity rotation: When one pumps, profits often flow to the other
Beta clustering: Both have high beta to BTC (\~2x), so they move together
FOMO dynamics: When retail FOMOs into one, the other often catches sympathy bids
When ADA spikes on retail FOMO and XRP doesn't, there's pressure for XRP to catch up OR ADA to fade. Either way, the spread normalizes.
10. Important Caveats
Walk-Forward Validation
We tested whether these results hold on data the model hadn't seen. The reality check:
Training period: +47.46% return, Sharpe 1.84
Testing period: +6.48% return, Sharpe 1.15
Degradation: 74% (significant overfitting detected)
Realistic Expectations
Expected Annual Return: 15-30% (not 69%)
Expected Sharpe: 0.6-1.2 (not 2.21)
Expected Max Drawdown: 25-35%
No Cointegration
None of our pairs showed true statistical cointegration (p-value for ADA/XRP was 0.96). This means we're trading correlation, not guaranteed mean reversion. Higher risk than "pure" stat arb.
Regime Change Risk
What if the ADA/XRP relationship breaks down? Maybe XRP wins its lawsuit and decouples. Maybe ADA gets a huge DeFi upgrade. The historical relationship could break.
11. The Bottom Line
Statistical arbitrage in crypto offers:
A way to profit that doesn't depend on "crypto going up"
Positive expectancy with an explainable edge
Capital efficiency through leverage
Market-neutral exposure (theoretically, but requires discipline)
But requires:
Understanding that backtests overstate performance
Discipline to stick with it through drawdowns
Acceptance that the edge can disappear
"Expectancy matters, not win rate. But expectancy without explanation is just curve-fitting."
