Redox reactions and standard electrode potentials

Hello, please help me with the following matter:

I have given the standard electrode potential for the reduction of silver triiodide to silver and three iodide ions. The value is -0.029 V. Then I have given other standard electrode potentials such as E0(H+/H2) = 0.000 V etc. The question is which of these compounds will the triiodide ion behave as an oxidant under standard conditions. I conclude that it will behave as an oxidant in combination with all those species that have a lower standard electrode potential than it (ie, in combination with hydrogen, the triiodide ion will be a reducing agent...). Am I right?

Thanks for your reply in advance!

All compounds who has lower potential as - 0.029V will work as reducer, what means triiodide will work as oxidiser in this case.

No, it is opposit. 0V is more positive as - 0.029V
