What are these?

Hi everyone, my first post as I'm totally new to Forex.

I'm trying to learn about FX and Ctrader while following Alex's videos which are awsome! 

On my graph Ihave various lines and arrows - is this something I've added in my noobiness and is it something I can remove as its annoying me while im trying to copy Alex.

Looking forward to working with the community.

Thanks 

Richard
