Taking electronic commerce as an example, the use of electronic decision trees does not present any novel problems. The provider of the service will be giving advice for the purpose of article 53 only if the service results in something more than a generic recommendation, as with a paper version.
Some software services involve the generation of specific buy, sell or hold signals relating to particular investments. These signals are liable, as a general rule, to be advice for the purposes of article 53 (as well as financial promotions) given by the person responsible for the provision of the software. The exception to this is where the user of the software is required to use enough control over the setting of parameters and inputting of information for the signals to be regarded as having been generated by him rather than by the software itself.
