Calling an array from inside a function

[tinkerz]

Error on triggering custom event for indicator 'DBAskBidFreqSenderv1': Object reference not set to an instance of an object

I have tracked this to an Array I declare

declared in Variables
private double [] cc;

declared in Initialize
double[] cc= {0.0,0.026670057901, 0.188176800078, 0.527201188932,
0.688459039454, 0.281172343661,-0.249846424327,
-0.195946274377, 0.127369340336, 0.093057364604,
-0.071394147166,-0.029457536822, 0.033212674059,
0.003606553567,-0.010733175483, 0.001395351747,
0.001992405295,-0.000685856695,-0.000116466855,
0.000093588670,-0.000013264203};

Then in a function I try to call it and get the above error

How can I call an array from inside a function?

Hi tinkerz,

Unfortunately, custom arrays like that are outside of the scope I can provide. However, the error means you are trying to access a value that does not yet exist, or is empty, null, during that context of the indicator.

Try declaring in variables with values, even if they are all zeros, then give them the values during Initialize or OnBarUpdate.

I think Tim inadvertantly gave you the correct answer, I believe you need to check the scope of your function and be sure that it includes the array object.
