ChartControl.GetXByTime() returns negative value

[grose]

Hi,

I call ChartControl.GetXByTime() in an indicator. When the indicator is running on a chart with live data, the function call returns a negative value. I have the indicator calculated to update tick by tick (CalculateOnBarClose = false) and I use an index value of 1 to look one bar back.

Has anyone seen this behavior and does anyone know of a fix?

Thanks,

Gordon

Hello Gordon,

As a heads up, ChartControl.GetXByTime() is not documented in the NinjaTrader help guide.

If you are printing in OnBarUpdate and allowing for prints to be made historically, this will print for each historical bar on the chart (including the ones not visible to the left of the chart).

For any bars that are to the left of the chart, these will have a negative value.

For any bars visible on the chart, these will have a positive value.

Are you viewing multiple prints?
If so, are all of the prints producing negative values, or are the most recent prints at the bottom with positive values?

Hi Chelsea,

Thanks for your answer. I realized this was happening if the chart was minimized, and that makes sense. It was tough at first to see the connection and then it hit me. It appears the window can't be minimized and of course the bar referenced has to be visible on the chart (if the referenced bar has been scrolled out of view, then the x coordinate won't be on the visible chart either). Hopefully all of this will help someone down the road with the function and the values it returns.

Regards,

Gordon
