Just don't do it, its not call arbitrage, its "TOTAL LOST".
Let me explain why I said so.
1) Assume that you buy BTC at $130 each at BTC-E.
2) You then transfer it to Mt Gox and sell it at $150 each.
3) On paper you profit $20 but you can't withdraw any money from Mt Gox.
4) Mt Gox goes bankrupt and you lost everything
End of story.
