TRADING 
2.1 E-trading Services in Retail 
Banking 
There are three core activities upon each trading 
transaction: stock-market data analysis, stock 
purchasing, and stock portfolio management and 
reporting. For e-trading to succeed as the as the 
preferred medium for trading, it has to provide the 
aforementioned activities in addition to 
authentication, mapping of available services and 
alerts to-stock market movements. 
Good trading services would not present information 
overload, but provide the right balance of 
information and functionalities. P&C technique 
establishes this balance to obtain optimal usability. 
These techniques allow the user to individualise the 
stock-trading experience by providing means that 
allows the user to specify and meets their own 
requirements through user profiles. Successfully 
implemented, the trading service uses these profiles 
to predict users' actions and provides information 
and functions pre-empt of request. 
2.2 Personalisation and 
Customisation: Concepts and 
Measures 
Personalisation and Customisation is the act of 
manipulating information and functionality based on 
the users' profile or previous activities (implicit), or 
set by the user (explicit). These P&C techniques are: 
Explicit customisation refers to the case whereby the 
user explicitly customises any part of the 
functionality or interface based on revealed 
requirements, e.g. optimisation of navigation using 
"My Favourites" (msn.com). 
Profile based customisation uses a profile of 
interests and behaviour that is built up of the user to 
select the appropriate content or functions to display, 
e.g. localisation of language and content 
(google.com); pre-population of form entries 
(yahoo.com). 
Behaviour or "click-stream" based customisation 
selects content or service to display based on the 
users' behaviour of past activity, e.g. automatic 
notification of updates to previously visited pages 
(vbulletin.com). 
Collaborative based customisation considers past 
behaviour patterns of a service user or community of 
users, e.g. recommended of contents to which others 
users in the same context are most interested in 
(amazon.com). 
 
A system that provides services normally 
comprises of an interface layer and a functionality 
layer. The functionality layer defines all business 
functions that are made available through the 
interface. This architecture tends to offer all users 
with the same set of system functions and services. 
Extension by another layer (P&C layer) allows rules 
to filter only the relevant content and specific 
functionalities, as shown in Figure 1. These 
personalisation rules are governed by user and 
content profiles. User profiles contain attributes the 
location, job title and interests of the user. Content 
profiles would contain the price, brand and creator 
of the product (Instone, 2000).

Figure 1: P&C information architecture 
The level of user involvement determines the 
balance of implicit to explicit P&C techniques used 
in a system. The degree of P&C use must be 
monitored, as too heavy use of explicit user 
involvement upfront discourages users. With the 
right balance of explicit and implicit involvement, 
users build up trust and are more willing to commit 
more sensitive profile information. Implementing 
P&C techniques in e-trading service will foster 
costumer trust and clearly defined responsibility of 
the e-trading service would encourage loyalty and 
customer retention. 
2.3 Research Methodology 
A survey followed by a qualitative analysis features 
the research approach we have adopted. The survey 
takes a cross section of top performing e-trading 
companies across Europe and the US. They are E-
trade (US), Charles Schwab (US), Reuters (US), TD 
Waterhouse (US), Ameritrade (US), Egg (UK), 
Royal Bank of Scotland (UK), Alex (the 
Netherlands), and Binck (the Netherlands). The use 
of P&C techniques was highlighted and evaluated 
for all trading activities in each of the nine
