I keep a good portion of my futures trading account in banks earning ~ 1% interest (it comes to a good chunk of cash for larger accounts at the end of the year). And I transfer funds into the FCM as needed for routine drawdowns so that I do not have to decrease leverage.
The banks I've encountered only process wire transfers once a day, near the end of the day, at about 4 p.m. ET. And the cut-off time to request the wire is about 3 p.m. So, if you want to wait for nearing the market's RTH close to decide whether or not to transfer additional funds to your FCM, and you initiate the wire at ~ 3:30 p.m. on Monday, your funds won't be sent until 4 p.m. on Tuesday, and maybe won't be available to be utilized at your FCM until Wednesday. And that's too long.
There's no bank I've seen that processes wires more than once a day (and near the end of the day).
Is there any bank that processes outgoing wires at least twice a day, say at 10 a.m. and 4 p.m.? Is there any method of moving money faster?
