Understanding stock market charts as visual arguments
(Philosophy of Language, )

Visual arguments are usually presented in the form of drawings, images, graphs, charts etc. and can play a key role in areas such as advertising, politics, financial markets, and so on. On the example of stock exchanges, we can see not only the use of non-verbal arguments, but also evaluate them as visual ones proceeding through rhetorical and demonstrative modes. Rhetorical mode involves the perception of visual images as premises of certain reasoning from which one can conclude (as well as in verbal argumentation). In the demonstrative mode images are put forward in support of certain conclusions turning to the visual channel of perception. Thereby, stock market charts demonstrate gradual price movements, which we can rhetorically clarify as value changes of a particular asset.

Stock market charts as well as visual arguments can be ``framed'', which means we incorporate one image of price changes into another one, thus expanding the field of perception and interpretation of an argument. ``Framing'' provides additional premises which can significantly affect the obtained conclusion. For example, we can place an image of four-hour-chart in a weekly graph expanding the understanding of which trend dominates the market in a more global perspective. Thus, the original image becomes one of the premises in the new reasoning, significantly influencing the subsequent conclusion. Conclusions based on four-hour candles and weekly ones can vary considerably. The search for alternatives in the rhetorical and/or demonstrative modes leads to radical changes in the conclusions.
