Crosshairs with 2 additional Lines +/- X pips away

Hi everyone,

can somebody please help me building a srcipt for the Crosshairs, which shows 2 horizontal Lines +/- X pips away from price?

For example, X=20, if you move the cursor to 1.3617, there would be a line at 1.3637 and 1.3597.

That would be a really useful tool.


Thanks

It would look like this. Has anyone heard of this tool already?

I dont know if its even possible to program this.


Thanks
