Im looking to develop a study that will allow me to translate futures prices into ETF prices. For example, ES trading 2076.50 is SPY 208.30, and every 10 cents is a 1$ of /es. I need to overlay the price on the chart at a defined interval (5 or 10 cents) based on a calculation of the price at that level. I wanted to see if anyone had a better idea than this. I will just take the cash open price, and calculate 20 levels up and down from there, making 40 levels to be drawn. Using the DRAWING_TEXT i can pepper the current level with my grid. The problem is that text tool doesnt allow forward projection per documentation, so it may work ok for the tradedom, but will look terrible on the chart. I also considered using 40 subgraphs of type text, which would let me project into the forward space, and should work in the tradedom and chart successfully. Any thoughts on the better approach or is there a better way you can think of?

i ended up using DRAWING_TEXT tools, which seemed to work well in DOM and on a chart. nasty little gotcha around the .BeginDateTime for usage on the DOM vs chart expansion area. attaching proof of concept code for the community. this thing needs work to function for various instruments, but hopefully will help someone else looking for this graphic approach.
