I am developing a range of short and medium-term trading systems,
all of which will have three pre-requisites before a possible trade
will be considered.

(1) The trade must be with the trend, as evidenced by the 200
day SMA of Australia's All Ordinaries index, symbol XAO;
(2) The index for the sector in which the intended trade resides
must be rising (or falling in the case of a bear market) at a higher
rate than XAO; and
(3) The stock must be rising (or falling) at a rate higher than
the relevant sector index.

The first one is easily achieved and I currently determine numbers
two and three by using the ROC function (ROC(Mov
((C/P),13,S),1,%), . That is, I run a thirteen week ROC for each
sector against XAO and then I run the same ROC for each stock in a
sector against that sector's index. That works, but it is a bit
time-consuming.

Is it possible to develop Metastock code that will automatically do
the above and that I could then build in to all subsequent trading
systems that I develop? I assume that I can use the Relative
Strength Comparator, but I'm not sure how?

Appreciate all advice.

John
