Getting alerts for indicators and strats is good to easy the eyes of the charts for a while :)
After my first script itroducing how to do alerts here there is an easier, more clear way to create an alert. It's still good to do it the "old way" to understand/debug an alert, but after that you'll want this extra tool for sure.
I assume you read my previous post, or understand how alerts are set up on a chart.
So, there is this function called alercondition() that does (almost)the whole job for us :)
The function does NOT create the alert automatically, what is does is introducing a new option in the alerts popup. While in the v1.0 of my script the alert was triggered checking for the plot value against 0.9 or -0.9, in this example the alertcondition() function just fires the alert by itself.
Get the script for yourself, in favourites, copy/paste, whatever. Add it to any chart. Then, open the popup to create an alert(the little clock at the top). There will be a drop menu with the options <ticker_symbol_chosen> and "Alert reloaded". This is the title provided in the study() parameter. Choose this one.
Now, the second drop menu has the "going UP" and "going DOWN" options. These are the titles from the alertcondition() function. Select one. Make all the aditional choices for the alert you want. Save it.
And that's it, the alert will fire when the conditions become true. You can still keep the plot() for graphical reference, but it's now an extra, removing it will not affect the alert, so more space in the chart. Yey!! :)
