A rainy Causeway Bay habit: write the assumptions
Paper beside the monitor beats memory when funding, fees, and margin mode change overnight.
After every Risk Clinic we send a one-page note. Clients who keep a similar scrap beside the PC — date, exchange, contract, margin mode, fee rate, funding assumption — can reopen Smart Crypto Calculator PC the next morning and recreate the same liquidation line.
The habit sounds small. It prevents arguing with a number you cannot rebuild. On wet evenings in Causeway Bay, when screens glare and patience thins, that scrap of paper is often the most valuable leave-behind from the session.
