On render and drawing rectagles based on price and time

[ballboy11]

Is there a way to draw a rectangle based on the price and time of the chart using onRender. I understand float and drawing on the screen, but not sure howto get that value from price and time.

Hello ballboy11,

You can find the conversion methods for X/Y values in the following two pages:

https://ninjatrader.com/support/helpGuides/nt8/en-us/chartcontrol.htm

https://ninjatrader.com/support/helpGuides/nt8/en-us/chartscale.htm

If you already have a price/time value and wanted to convert to X/Y you can use the following:

For converting a time to an X value use ChartControl.GetXByTime()
For converting a Price to Y value use ChartScale.GetYByValue()

To collect prices/times you can use the GetValueAt() method to retrieve price/time data from the series:

Close.GetValueAt(i)
Time.GetValueAt(i)

I look forward to being of further assistance.
