Elvis has left the building - Massive Rainfall

Unfortunately, the MtGox Bitcoin Exchange has stopped or collapsed – and as a result Massive Rainfall has:

halted (or frozen) any Securities that are derived from that exchange.
halted (or ‘frozen’) any outstanding Orders that will also be cancelled eventually.
Open trades will be marked to the last closing price and will expire immediately.

Doing this was relatively straight forward – though I should automate this for ease-of-use.

Massive Rainfall Derivatives Exchange (MRDE) will continue to allow other Bitcoin futures to trade using other underlying Bitcoin Exchanges (search on CAD or USD for a list of Bitcoin Futures currently available).
