MT5 swaps and rollover: read the symbol before holding overnight
Two trades with similar entry and exit prices can finish with different net results if they stay open for different lengths of time. Overnight financing is a separate item worth reading in the symbol specification and account history.
Read the units first
Symbol properties include swap mode, long and short swap values, and rollover-day information. A displayed number is not automatically a dollar charge per lot. Its meaning depends on the calculation mode and contract configuration.
Build a holding calendar
For a hypothetical comparison, keep direction and volume constant and compare a same-day trade with an overnight trade. Note the broker server dates, number of rollovers and any multiplier. Do not assume that every instrument uses Wednesday for its larger rollover.
Reconcile the account history
Record realised price profit, commission and swap separately. If a statement books adjustments in separate rows, include them in the reconciliation. Avoid counting the same swap both inside a reported net figure and again as an extra deduction.
Explore a purposeful change
Source access lets you investigate a maximum holding period or a rule around rollover. Ask AI to show which existing exits remain active and how an open position is treated when the cutoff arrives. Compare the new rule on identical data before attributing any difference solely to financing.
