How to mark a place in time

 
I'm wondering how I would note a place in time once discovered through a loop. I don't have any code prepared but my intention is to run a FOR loop looking for the place where the MACD value is higher than the current value.

Doing that much I understand, but I now want to look at price at that exact time and I'm not sure how to do that. 

Would anyone mind sharing their ideas on how I might do this? I appreciate your help. Thank you in advance. 
 
Perhaps you should read the manual. iBarShift to convert your "exact time" to a bar index. Use that to read bar values.
