Event-Risk Position Reductions: A Worked Crypto Example With Fees Included

Cutting size before a scheduled event costs fees and slippage. Whether that's worth it depends on how far price could gap past your stop.

Short answer

An event-risk reduction trims a position before a scheduled event (a macro release, an exchange upgrade) to limit gap risk. Example: 2 BTC long at $60,000; halving to 1 BTC before the event and re-entering after costs ≈ $30 to exit, ≈ $30 to re-enter and ≈ $10 of slippage — about $70. If the event gaps price 3% through the stop, the loss is about $3,600 on 2 BTC versus $1,800 on 1 BTC. The reduction costs little relative to the gap it insures against; the cost is missing part of a favourable move.

Sources and methodology

Arithmetic uses standard sizing formulas. Fee rates (0.05% taker, 0.02% maker), slippage and funding values are illustrative; check your venue's schedule. Liquidation figures are simplified approximations; exchanges calculate them with their own maintenance-margin rules (see Bybit's documentation).
