Abstract: Methods, systems, and apparatuses, including computer programs encoded on computer-readable media, for receiving configuration data comprising an indication of a first security or index, an original price of the first security or index, and a first audio indicator type. Pricing data of the first security or index is received and a change in price of the first security or index is determined based upon the received pricing data and the original price. A first audio property of a first audio indicator is determined based upon the change in price and the first audio indicator type, and the first audio indicator is played.
