Usually the one touch trading system offered by 24option is a system to provide the individual trader that has a sense of security. Most binary options include set times of expiration and nothing about the trade can be changed between the time of purchase plus the expiration time. This is one good reason that the expiration periods of the options are generally set for short duration.
The one touch buying and selling platform allows the trader to ascertain a target price for your asset and when the particular asset reaches that targeted price the trader will cash in on their prediction given that the expiration period have not ended.
