Crossover Alerts for Yesterday O/H/L/C , Today Vwap [Zero54]

This is a very simple script/indicator that trigger alerts every time the script triggers the following conditions.
1) Script crosses yesterday's (previous day's) high
2) Script crosses yesterday's (previous day's) low
3) Script crosses yesterday's (previous day's) open
4) Script crosses yesterday's (previous day's) close
5) Script crosses today's vwap.

I developed this to keep track of the scripts I follow and I find it useful. Hope you will find it useful too.

Steps to use:
1) Open the ticker for which you want to set the alerts.
2) Add this indicator to the chart.
3) Right Click on the text and set choose "Add Alert"
4) After you have done with setting up the alert, feel free to remove the indicator from the chart. It is not necessary for the indicator to be added in the chart in order for it to work.
5) Repeat 1-4 for all the scripts for which you want to set the alerts.

Be advised: During market open, if you have set alerts for multiple scripts, a tsunami of alerts may be triggered.

If you like this alert indicator, please like/boost it. Feel free to re-use this code however you may wish to. Cheers!
