Rattraders in the laboratory.
The sound is modulated in correlation to the price movement: if the price goes up, the pitch goes up as well, always depending on how strong the up-movement had been. When prices drop, the following sound's pitch is reduced depending on how strong the price has fallen. Always in regard to how long it took for the next trade to happen (time between trades can vary between 1 second and 1 minute occasionally), I used different kinds of piano modulations. After some tests, we found that our probands reacted best to 25 price ticks or sounds, so one track was to take 10 to 20 seconds accordingly, depending on the market movements.
The following illustrations show some of the charts and historic real time data used; the viewer might also get an impression of what the sound files looked like.
This way we were able to listen to the Sound of Futures Markets. Keep in mind that the data used are only tick data, representing only the last 3 digits of the futures quote.
Financial data such as these are turned into sound for the rats´s training units.
