Cond = Cross( MA (Close, 20), MA(Close, 50) );
Cond1 = Cross( MA (Close, 50), MA(Close, 20) );
Buy = Cond;
Sell = Cond1;
Well i pointed to using ROC
Slope20 = ROC(ma(c,20),1);
Slope50 = ROC(ma(c,50),1);
to help yourself see what type of results use an exploration to provide numbers
filter=cond or cond1;
addcolumn(slope20,"slope20,1.3);
addcolumn(slope50,"slope50,1.3);
checking this against your charts you can work out the slope value you
want, then add this to your buy/sell conditions, something like this
eg
buy = cond and roc(ma(c,20),1)>0.5;
