In this strategy, we do not buy the actual coin.
We open two positions on futures markets across different exchanges: on one — a Long (bet on price increase), on the other — a Short (bet on price decrease).
1. Leverage: You can use leverage on both sides. This allows you to trade volumes that significantly exceed your actual capital.
Not for beginners. Risks increase.
2. Double Funding: You either receive or pay funding fees on both exchanges simultaneously. Our task is to calculate the final result (the sum of both funding rates).
An arbitrage trader always looks for the most profitable combination of price spread and total funding.
1. Ideal Scenario: Spread + Positive Funding
This is when the total funding from both exchanges generates additional profit.
· Option A: On both exchanges, funding pays you. (For example, on one exchange you are in Short and funding is positive, while on the other you are in Long and funding is negative.)
· Option B: On one exchange you receive more than you pay on the other.
Example: On Exchange #1 you are Short and receive +0.2%. On Exchange #2 you are Long and pay -0.1%.
Result: Your net funding income is +0.1% every 8 hours.
2. Basic Scenario: Spread Only
Funding on both exchanges is approximately equal and cancels out, or it is so small that it can be ignored.
· Example: On both exchanges funding is +0.01%. On one side you pay it, on the other — you receive it.
· Result: You break even on funding and profit only from price convergence between exchanges.
3. Spread Priority: Spread Is More Profitable Than Funding
This is when total funding is negative for you (you pay on both exchanges, or one pays less than the other takes), but the price spread covers these costs.
· Example: Over 24 hours you lose 0.05% on funding, but the spread between exchanges is 2%.
· Logic: It is still profitable to enter the trade, capture the 2% spread, and exit quickly without worrying about the small funding loss.
1. Monitor Margin: If the coin price spikes upward, your Short will be at a loss while your Long will be profitable. You must have sufficient USDT reserve so the losing side is not liquidated.
2. Fees: You open two positions, so you pay opening and closing fees on both exchanges. On average, total fees across two exchanges range from 0.2% to 0.4%.
