Better don't mix pink blocks with other blocks. If you use pink blocks, the best is if you use only pink blocks (and Condition with the pink-dot "(in loop)..." option).
Bucket of Trades is mostly used to select group of trades with the idea to get some information out of them later in Condition block. Not to take action over them. In theory it is possible for me to add some purple "close" button s all trades selected by this block can be closed with it, but...
Why don't you try something like this: http://prntscr.com/dn9v4c
