modification to "once per bar" block?

[Jnmr1]

Hello,
I was wondering if it would be possible to modify the "once per bar" block in the mql5 side of Fxdreema so that there is an option for it to only pass at the opening of the bar?
The problem I'm having is if the terminal is restarted before the next block is created, I get a duplicate trade because the "once per bar" block passes again (once at the creation of the block, and again whenever the terminal is restarted).
I'm pretty sure I can do what I want with multiple time filters. But that would further complicate an already complex EA.

thank you
James
