Use a bool to remember you did the Alert, on the next bar reset the bool so you can do another Alert . . .

3. What you posted won't even compile, no such variable SYMBOL_ARROWDOWN

4. Where is your attempt? Since there are no slaves here, there are only two choices: learn to code or pay someone. We're not going to code it FOR you. We are willing to HELP you.
