Horizontal lines disappear

[cstrader]

So I'm drawing some horizontal lines using DrawLine() from ninascript on a 1 min chart. As the day progresses the lines variously show and disappear, and the same happens when I manually scroll left and right.

Any thoughts appreciated.

Hello cstrader,

Thanks for your post.

Unfortunately this is a limitation. If the anchor points of the draw objects are out of the visible range of the chart then the draw object will not show up.

This is is being addressed in the next major release of NinjaTrader.

Please let me know if i can be of further assistance.

Is is possible to find the first and last visible bars from ninjascript?

Also, I'm not really sure this is the problem. It doesn't seem that the lines disappears when their begin and end points leave the visible area. They do disappear at some point, but when isn't all that clear.

Thanks

Hello cstrader,

Thanks for your replies.

It is possible to find the displayed bars but to do so would be using an unsupported method. ChartControl.FirstBarPainted and LastBarPainted Please see this thread for references: http://www.ninjatrader.com/support/f...ad.php?t=23979
