Amibroker Coding

Hello, I need someone to complete some exploration code for me. I want to add a filter so that the highest closing price in the year prior to the last year is greater than the highest closing price in the last year. For example, todays date is 23/9/2024. I want to make sure the highest closing price in the one year period 23/9/22-22/9/23 is greater than the highest closing price in the year 23/9/23-23/9/24.

Please code the one year period in days so I can alter the time period if needed easily

Thanks
