Hello,
The block are for 2 reasons:
1. To organise triggers (visually, for copying/pasting, etc.)
2. For cycle complicated routines (to execute bunch of triggers several times).
If you need to place these bets at the same time you could just add a second action to the same trigger. If you need to place second bet when the price reaches 1.13 then there are 2 options:
1. Add conditions to the trigger for each situation (a bit complicated)
2. Create second trigger.
So you don't really need a block for this.
