I have a quick rather "noob" question about MtGox. I've noticed many reports about MtGox being very slow at "paying out" usd, and have seen many people suggesting that you should transfer your bitcoins to Coinbase before selling them, so you can get your USD faster.

However I have a simpler question, if I want to sell a bitcoin on mtgox, am I "stuck"? Meaning if I sell 1 bitcoin for, example ($1000 usd), would the 1000 usd immediately be tried to be put into my bank account and then be "on hold"? Or could I take that 1000 usd and immediately buy another 1 bitcoin about 5 minutes later when it is $900.

I am basically trying to evaluate the possibility of a "quick turnaround" on MtGox buying and selling bitcoins, the equivalent of a "Day Trader" in the stock market

Thanks!
