Designing a Spot Crypto Hedge with Rebalancing and Execution Controls
Summary
This tutorial designs a spot arbitrage strategy that buys on the lower-priced exchange and sells on the higher-priced one. It lays out controls for the minimum and maximum trade size, price and quantity precision, exchange-rate conversion, and a spread threshold intended to account for fees and slippage. The implementation requests order book data concurrently, checks available depth and balances, and submits paired orders. It also cancels outstanding orders and periodically compares total coin holdings with an initial baseline, trading to reduce any imbalance. The article describes converting quote currencies so prices and account balances can be compared consistently.
The document includes substantial platform-specific implementation detail, including persistent initial-account data and status reporting, but the hedge depends on inventory and quote-currency availability. If one exchange has sold its coin inventory while the other has accumulated coin, the strategy may have to wait for prices to reverse before it can continue hedging. The examples do not establish profitability or fully resolve risks such as partial fills, transfer or exchange outages, fee variation, and imperfect rebalancing.
Key ideas
- The strategy buys on the lower-priced exchange and sells on the higher-priced exchange when the spread clears a configured threshold.
- Trade sizing accounts for available order book depth, minimum and maximum quantities, and account balances.
- A periodic balance function compares current total coin holdings with an initial baseline and trades to reduce discrepancies.
- Concurrent order book requests and cancellation of unfilled orders are part of the execution design.
- Currency conversion and exchange-specific precision must be handled for consistent comparisons and valid orders.
- Inventory constraints can halt further hedging until prices reverse, and the tutorial does not establish profitability.
