Automated FIAT Transfer to bank from Exchange
This would vary widely by exchange. The BTC transfer and trade can almost definitely be automated through most large exchange's APIs. Fiat withdrawals might be possible, but I don't recall seeing any APIs for that recently. Your best bet would be to contact the exchanges and ask about it, as I suspect it is a feature that is available "on-demand" for larger clients, and they might be willing to support you on it.
