Friends, I made this code to go quickly through all stocks of interest. Have a look of 3 seconds in each one.

For some of them I would like to make a pause, for example by hitting space or clicking the chart. So the EA stops, I look more carefully then, it continues showing the charts of the next stocks in the list.

How can I do this ?

Thanks!

douglas14: I would like to make a pause,

1. What happens when your posted code i becomes 8?
   

2. Show us your code where you check for a space or a click? Show us your attempt (using the CODE button) and state the nature of your problem.

There are no pauses: clicking on the chart causes the symbol to change:
