How does the deposit amount stay equal to the dollar figure I credit?

halfin locks the conversion rate when the invoice activates and stamps a payment window. The trader is shown a fixed token amount; pay inside the window and that amount settles to exactly the fiat figure you priced, so the credit to the trading account matches what the trader funded. If the window lapses, the invoice expires rather than re-pricing against a newer rate, and the trader re-issues at the current rate.
