j,
If you want the slope based on the value today and yesterday, I
would use MA(close,x)-MA(ref(close,-1),x), where x is the length of
the moving average. This is the old "rise over run" from algebra.
However, you should normalize this value if you want to compare it
to something else. Say stock A has a MA that was 100 yesterday and
105 today. The slope would be 5. Stock B has a MA that was 10
yesterday and 10.5 today. The slope would be 0.5. But both changed
by the same percentage. So you could divide both values by the MA
yesterday, then both would be 0.05, the same "slope".
Maybe one of the experts out there could clarify one thing:
Is MA(ref(close,-1),x) the same as ref(MA(close,x),-1) ?
For the buyprice question, it would be buyprice=MA(close,x)-0.25;
Hope that helps,
Jim
