Alberto, these are some of the benefits derived by paying for the use of Intelledgence :-
a) Which of the ASX200 to buy ? (Most probably the easiest thing to do on your own); however some of the signals are given before the SPA ones kick in, so it's not tardy),
b) then it weights the quantity to buy with a level of portfolio risk,
c) and provides a technical stop loss,
d) it provides accumulate and lighten signals
e) and then it will preserve capital with a sell signal.

As to the frequency of watching a portfolio performance and waiting for signals, well that's a personal choice and one can subscribe to the email alerts for the signals and therefore act on a timely basis.
