Sometimes, my NT8 gets slow so candles can't keep up with the current bid/ask.
The easiest way I found is to delete or change NinjaTrader.sdf file inside db folder to OLD_NinjaTrader.sdf.
Doing so, it will definitely speed up plotting candles in real-time.
However, all of the arrows and lines I plotted on the chart disappear and I can't redraw them at the same price and same time mark.
I saved the chart as a template and load it up with a new chart but all other indicators appear except lines, arrows, and marks (like circle, diamond and rectangle).
Is there a way to keep these arrows and lines? I think there's a way to manually delete db selectively.
Your advice is greatly appreciated.
Thanks
