How long does it take for E-Trade to transfer money to bank?

Can you provide me with an estimated timeframe for the transfer of funds from E-Trade to my bank account? I'm curious to know if there's a standard duration that applies to most transactions or if it varies depending on certain factors like the time of day the transfer is initiated, the bank involved, or the amount being transferred. Additionally, are there any steps I can take to expedite the process or any potential delays I should be aware of?
