Referencing daily pip change and ADR

Hello everyone,

I was wondering if someone would be kind enough to help me with a simple code. 

The code I want to do is something as follows:

"if daily pip change >= 1/2*ATR, send me email"

where daily pip change is

ATR is average true range indicator for D1 or daily timeframe with 22 periods, of any forex pair (or a group of forex pairs as specified by me).

When I say  >= 1/2 of ATR, I mean regardless of negative or positive value. 

In practice, this is how it should go - if for example, GBPUSD has an ATR of 120 pips, and If today, GBPUSD hits +60 OR -60 pips or greater, I get an e-mail.
