Buy both outcomes below $1 → hold → guaranteed profit.
But in real trading, this breaks without one key component:
Risk management.
The real risk is not price direction — it’s execution imbalance.
The Real Risk: Unpaired Exposure
In theory:
Buy UP at 0.47
Buy DOWN at 0.46
Total = 0.93 → locked profit.
In practice:
One side fills
The other doesn’t
Time runs out
If the market resolves before completing the pair, you face a full loss.
So the focus must be:
Resolve imbalance, not just find price edges.
Core Risk Management Principles 1. Limit Unpaired Inventory
Never allow unlimited exposure on one side.
Track unpaired tokens and stop new buys when imbalance exceeds a threshold.
Result: Prevents runaway risk.
2. Time-Based Forced Hedging
The most important safeguard.
If the opposite side isn’t filled within a set time:
Force-buy it at a more aggressive price.
This reduces profit slightly but guarantees completion.
3. Progressive Hedging
Don’t wait for perfect fills.
As imbalance grows:
Hedge small portions early
Increase hedge size over time
Result: Avoids costly last-second execution.
4. Liquidity-Aware Execution
Not all opportunities are real.
Check:
Orderbook depth
Spread
Fill probability
If liquidity is weak, reduce size or skip.
5. Time Window Control
Markets become unstable near resolution.
Best practice:
Trade only between defined times (e.g., 300s → 90s)
Avoid late entries
Complete all pairs before final window
6. Emergency Hedging
Near market close:
Close all unpaired positions immediately.
Even if it means crossing the spread and accepting worse prices.
7. Order Escalation
Limit orders improve profit but reduce fill rate.
Use a layered approach:
Passive limit
Retry with better pricing
Aggressive fill if needed
Result: Higher completion rate.
8. Edge Validation
Not every “cheap pair” is profitable.
Before entering:
Include slippage and execution cost
Reject weak setups
9. Inventory Skew Control
When imbalance appears:
Prioritize buying the missing side
Reduce buying the dominant side
This naturally rebalances positions.
The Role of the Hedge Manager
A proper system separates hedging logic.
The hedge_manager handles:
Forced hedging
Partial hedging
Emergency closing
Execution escalation
Its goal:
Ensure every position becomes a complete pair.
Final Insight
Dual-side arbitrage is not truly risk-free.
In reality:
Fills are uneven
Liquidity disappears
Time is limited
The real edge is not finding opportunities —
It’s how effectively you neutralize risk.
A successful bot:
avoids getting stuck
resolves imbalance fast
exits fully hedged
That’s what makes the strategy work.
