I try to use sc.GetPointOfControlPriceVolumeForBar() to find the POC price of a bar with code below int BarIndex const s_VolumeAtPriceV2 *p_VolumeAtPrice=NULL; sc.GetPointOfControlPriceVolumeForBar(BarIndex,&p_VolumeAtPrice); and get the compile error as below:- error: invalid initialization of non-const reference of type 's_VolumeAtPriceV2&' from an rvalue of type 'const s_VolumeAtPriceV2**' sc.GetPointOfControlPriceVolumeForBar(BarIndex,&p_VolumeAtPrice); By referring the link:- sc.GetPointOfControlPriceVolumeForBar() It does not provide example how to use this function. Could u provide the example or correct syntax for it? |

Make sure you define s_VolumeAtPriceV2 as a const: const s_VolumeAtPriceV2 *

I have defined const as follows:- const s_VolumeAtPriceV2 *p_VolumeAtPrice=NULL; Is it correct? |

We apologize we did not have a close look at this. This is how it needs to be: s_VolumeAtPriceV2 VolumeAtPrice;
sc.GetPointOfControlPriceVolumeForBar(BarIndex, VolumeAtPrice); We will update the documentation with an example. Sierra Chart Support - Engineering Level Your definitive source for support.

Now it can be successfully complied. However, I want to get the POC price value. I try to get the POC price by s_VolumeAtPriceV2 VolumeAtPrice; float POCprice; int BarIndex sc.GetPointOfControlPriceVolumeForBar(BarIndex, VolumeAtPrice); POCprice=VolumeAtPrice.PriceInTicks * sc.TickSize; The =VolumeAtPrice.PriceInTicks value seems incorrect. Do this function return volume of POC only and I should not use it for POC price? If it is inapporiate, any suggestion to achieve my purpose? |

There was a problem with this function and has been resolved . We will have a new release out today or tomorrow. And we have also done an additional update to the documentation. You need to add this line to your code: sc.MaintainVolumeAtPriceData = 1; Refer to the updated documentation. Sierra Chart Support - Engineering Level Your definitive source for support.
