Firstly, using Magento CRON is not possible for sub-one-minute scheduling; so if 30 second updates are critical you're going to have to use another method - or reconsider using Magento. I would suggest using AJAX to update the pricing on the product page and using a webservice to grab the price at the time of the product add. You'll have to leverage observers to update the price on add.

If you are going to use custom pricing for products you won't be able to take advantage of the pricing index - and you'll have to use the setCustomPrice and setIsSuperMode methods on the product quote item - again, use observers for this. See the following two stack articles for more details - they do work in CE 1.6, 1.7 and EE 1.10, 1.11.
