Is there a NinjaScript method or other easy solution for converting the .NET Point type to X/Y (Bars/Price) coordinates and vice versa?

Point type to Bars/Price converter?

Hello,
Thank you for the question.
There are easy methods for this hidden in the ChartControl.
For X coordinates by bar number, you can use:
Code:ChartControl.GetXByBarIdx(BarsArray[0], 100)
Code:ChartControl.GetXByTime(Time[0]);
Code:ChartControl.GetYByValue(this, 2000);
Code:if(ChartControl != null) { //do stuff }

How do we convert back from the .NET x,y coordinates to NinjaTrader barnumber/price?
So we might have something like
double x = ChartControl.GetXByBarIdx(BarsArray[0], barnumber);
double y = ChartControl.GetYByValue(this, pricevalue);
//do some calculations using x,y and get updated values x1,y1
//we then want
int barnumber = GetBarNumber(x1);
double priceval = GetPrice(y1);
This is just dummy code but how would GetBarNumber(), GetPrice() be implemented?

Hello,
Thank you for the question.
For NT7 I would have no suggestion here as there are no exposed methods for this that I could relay. Going forward in NT8 the ChartControl and other chart-related coordinate methods have all been exposed so you can translate back and forth between coordinate and price/time.
If any other NT7 users have custom solutions for this question an answer would be welcome for any undocumented/unsupported solutions.
I look forward to being of further assistance.JesseNinjaTrader Customer Service
