BTC-E.com allows short selling via metatrader 4 platform with up to 3:1 leverage.
Charting example
Works just as well as any MT4 platform I've traded fiat currency pairs with.
BTE-e also offers crypto currency pairs other than BTC/USD
In case the text is to small/unclear
BTC/USD
LTC/USD
LTC/BTC
NMC/USD
BTC/EUR
LTC/EUR
BTC/RUB
LTC/RUB
Anyways, hope this helps.
Merry Christmas and Happy Holidays,
