How to make an EA alert message before it is attached?

This is my EA . I want it to alert message and ask confirmation to buy/sell when it is attached to mt4. If the answer is no, the ea wont execute buy/sell operation

But you attach it, you probably want it do to something? Otherwise I think you ca make a Script instead, and try that block "Prompt", it's somewhere on the bottom of the list.
