Trading-Journal Partial Fills in Crypto: When the Common Rule Produces a Misleading Result

'Use limit orders to save fees' is often right. With partial fills, the unfilled remainder can cost more than the fee saved.

Short answer

Limit orders earn maker fees but may fill partially. If the rest is then chased with a market order or never filled while price runs, the cost shows up as worse average price or missed profit — not as fees. A journal that tracks only fees will show limit orders as cheaper. Track fill rate, average price versus the price when you decided, and outcomes of unfilled portions to see the true cost.

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).
