Adding Logo Causes Slowness
When using this code found here It causes my indicator to destabilize and Ninjatrader stops working every now and then. Any way to avoid or correct this?
Code:Tags: None

Hello r3n3v,
Did you make modifications to that script? The code alone does not help to know what may be happening, do you see the same problem using the unmodified sample?
This could also relate to the image being used, have you tried another image?
Please let me know if I may be of further assistance.

Hello r3n3v,
Did you try the samples original image or a different one than you have used? It may be the image causing the problem if the original sample works fine. There is no specific documentation for the code you have used, that is an external library called sharpdx which NinjaTrader leverages for rendering. The linked sample is a generic sample found for use with sharpDX and has some modifications made to adapt to the NinjaTrader overrides.
Please let me know if I may be of further assistance.JesseNinjaTrader Customer Service
