Modification of Existing script Function : alert, push notification function.

Hello,I have a simple script,that close all orders/positions after defined profit or loss. I want to add a function to it so that, in addition to the closing function, the expert informs me (by push notification) when profit/loss reach a specific value.For example, 20 usd is set for Profit to close, and if the loss or profit is 15 usd,  or only loss is 30 USD,the script would send me push notification about it.
