The beta test is open for all users. The test itself is done to see if we are near an release already and to ensure everything works as desinged. And as soon as we got this confirmed we will issue the update to all the users. It is an normal release procedure with the exception this time the update itself is too big, thats why it is taken an long time to do this testing now.

@nanobit:
Going short is something we do not yet support, but its on the top of the request list to be added so in time we will support iton the exchanges that support it too. Once the support is there the DEMA (or any other indicator) can be used as an trigger.
