Hi Graham,
Thanks a lot. You're so nice.
Actually, I just need one simple formula, i.e., when 2 moving avgs
cross, as in this formula:
///////
Cond = Cross( MA (Close, 20), MA(Close, 50) );
Cond1 = Cross( MA (Close, 50), MA(Close, 20) );
Buy = Cond;
Sell = Cond1;
///////
I hope when a fast MA crosses a slow MA from bottom upward, the
slope of the crossover tangent point of the fast MA is more than
0.5. On the other hand, when a fast MA crosses a slow MA from top
downward, the slope of the crossover tangent point of the fast MA is
less than -0.5. That is, the "buy" signal must satisfy the
specified condition and with a slope > 0.5. On the other hand,
the "sell" signal must satisfy the specified condition and
with a slope < -0.5.
I understand that this slope must be calculated first, but I
don't know how to calculate it using AFL.
Could you please help me with this function? Your help would be
much appreciated.
Robert.
