Indicator that only draws lines read from a file

[GrumpyDude]

Hi,

I'm looking to create an indicator that will read levels from a .csv file (support/resistance, price, a ranking 1 to 5), and plot them on the chart. Basically this is a one time action once the "apply" or "ok" button is pressed. It is merely a convenience for plotting lines (like F6 Horizontal Lines) at the prices, with preset colors, thicknesses, and types based on the data from the .csv file.

I have much of the logic done, but am stumped for where I would call the file read and plot methods from for this one time action. Like which Calculate.??

Thanks

Hello GrumpyDude,

The reading code should go in OnStateChange -> DataLoaded, that is called once the script is setup and is only called once.

To draw a single time you could do that by waiting for the last bar in processing and then looping over your data. That can be done from OnBarUpdate using a condition like this:

if(CurrentBar == Count - 2)
{

}
