AO access problem

[mariusz]

Hello

I am trying to access AO indicator in my strategy

I am using following code for it:
======== to create AO indicator:

ind_AO := CreateIndicator(Currency, TimeFrame, 'AO', '5;34; Simple (SMA);(High+Low)/2');

======== to get values

AO_1 := GetIndicatorValue (ind_AO, 1, 3);
AO_2 := GetIndicatorValue (ind_AO, 1, 4);


but I receive illegal values in FXtester (pls see the picture)

what am I doing wrong?

thanks
