This morning my eyes were blurry from staring at screens the day before. It got me thinking random thoughts, as I often do on sat morning. Could the blind trade? What if one day I go blind or any of us suffer some unrepairable damage to the eye. Could traders still trade. My thought is yes in two parts. First there is the trader that has seen price action and charts and will know what to look for. In the case of being blind, it would be hear or feel. Some device would have to be made to represent the bid and the ask in an audible or tachtile form. My thinking was a machine like a mouse but with bumps, that would represent number values. Then combining and audible tone when a print goes off, nothing to annoying, a light chime. When the print goes off at the ask the chime is higher, and as it goes off at the bid the chime has a lower tone. This also serves to(depending on the sounds position in the selected scale of notes) depict short term price momentum. I thought about this for a moment, and knowing that when one of the five senses is gone, the others get hieghtened. I wonder how well with this setup a visually impaired person could learn to trade. They wouldn't see the montage games, and wouldn't have to watch the P&L fluctuate. Could that be an edge psychologically. Could a trader that can not detect a pattern visually be more attuned to an audio pattern? If so, would the trader even need to be blind in the first place? Well thats my thought of the day.
