Function Call

How do I go about calling up a function for use in a new function I am creating? I am stymied. The following compiles okay but when I try to add it to a chart I get
an error in formula message, specifically the AC = AO-SMA(AO,5) portion.

cFunctions.SetForwardAndBackwardBars (34, 0);
result = cFunctions.CompileFormula ("AC = AO - SMA(AO, 5);").GetVectorDouble ("AC");

I have successfully created and implemented AO, so it is in my functions file.

Thank you,
Darrell Allen

Best Answer

There is an error in the formula specified in "CompileFormula". The variable "AO" is unknown.

You should put instead:

cFunctions.SetForwardAndBackwardBars (34, 0);
result = cFunctions.CompileFormula ("a = (high + low) / 2; ao = sma(a, 5) - sma(a, 34); AC = ao - SMA(ao, 5);").GetVectorDouble ("AC");

You can also use the "TA" class instead of "CompileFormula"

VectorD a = (cFunctions.High + cFunctions.Low) / 2;
VectorD ao = TA.Sma(a, 5) - TA.Sma(a, 34);
result = ao - TA.Sma(ao, 5);
