Your formula looks fine. Here's another way of doing the same job.
a:=Mov(C,50,E);
b:=Mov(C,200,E);
Sum(Cross(a,b),4)>0;
Don't forget to use about 1000 (200*5) periods in your exploration, or the
longer moving average will be inaccurate. If your charts are significantly
less than 1000 bars then your 200 bar EMA will be off anyway.
