Thank you so much Ernst! Works perfectly as I was imagining!

Hello everyone!
I am totally new to this community. Please forgive me in case I am missing any rules (which I have tried so hard not to).
I am trying to create an object (arrow, thumbs, etc) in case of an event occurrence over the chart. For instance, if two EMA 50 and 200 crosses each other, it will create and object over the chart (I have attached a screen shot of an example).
I really appreciate it if someone helps me with completing my code or direct me to a post where I can learn it. (except the documentation).
Thank You
