doesn't tws support even both - close all positions and cancel all open
orders? Actually I used neither of them. But while the first one
certainly is a panic operation with a huge intrinsic risk of loss, the
second one in general I would consider as rather a risk reducing
operation and might be at least more useful than the first one, I think,
especially in automated or partly automated enviroments. Easy and
efficient for a clear result. But I even do not know wether it is
supported by the API at all.

Anyway: I still wonder how to cancel an order with unknown client id.
Looking loosely through the code, there is a class AllOpens. Is that
implemented?
Or, in a different approach: if I was clever enough, to store the
informations from an 'open' immediatly after each limit order, can I use
this information in a subsequent shim session 
to plug it into some sort of 'order(...'Cancel'..) command?
