If you place a market order, then speed of execution will be essentially the same as with a stock order, though lower liquidity could create some delays. If you use a stop or limit order, then obviously there are other considerations.
Confirmation timing most certainly should come the same day, but the timing of that is all based on your broker. I personally get confirmation on my trading screen as soon as the transaction is executed, then an email at the end of the day or overnight.
