Pivot level break alert

[arjunrose]

Hi can anyone tell me how to adapt the esignal monthly pivot code to alert me if the previous days candle on a chart has pierced either s1,s2 or r1,r2 on the monthly pivot efs?

Preferably I would like the chart background to change colour as I am looking at many charts on the same page and I could identify the relevant ones quickly.

Thanks in advance!
