Hi
Need some more information!
However, from the question, I would think you are talking about when,
EMA either is below or crosses other EMA
and
when RSI is either below or crosses a level.
Here is a very basic example and I hope I understood your question correctly.

Merely change block 2 and block 3 around for EMA to be first condition and RSI second condition.
I might be incorrect, but 1 condition doesnt have to ( <x ) as this is ( cross over ), you could merely use ( < ) as 1st condition should be "below"
and then 2nd condition ( <x ) "cross below"
Eample link explained:
When RSI is ( < ) "below" level 30
and
50EMA (<x ) "crosses below" 200EMA open buy trade.
I hope this helps a little, I'm still new here, sorry if this is not what you were looking for.
