Hello there,
I'm looking to draw a histogram that plots data pulled from the web (csv is fine), updated with each new period. Is this possible with Investor RT/RTL? I tried the built in EDI indicator but it did not plot anything, even after following the example format.
Thank you,
Marko
Hi Marko,
just providing some feedback here : I think EDI is not designed to import historical quotes, but rather support/resistance type of levels..
What type of data do you want to import ? tick data ? 1 min bar ? daily quotes ? with which frequency ?
Depending on your answer, you will need most likely to create first a recipient for your quotes -(ie a custom cash instrument) and then populate it using one of the data import file format... (see the available prep programmed settings by clicking on the icon in the data > import data window / alt+7 might work as a shortcut)
Then, you might want to run a schedule in order to automate the import data process

Thanks, Eddy. We're looking to import non price data and plot it in a separate panel under the price chart. Periods are flexible, but we'd probably be using 5-min. We'd like to render the data in histogram form , which I see may be supported by EDI judging by the tick box? Also are web calls in form of AJAX/JSON supported by any platform functionality or API functions (RTL, RTX)?
Thank you again!
Marko
Hi Marko,
i think it should work with EDI but i am not enough familiar with this feature to further guide you.
I'll ask Chad if he can provide more feedback
Eddy
Much appreciate it, Eddy and Chad.

So you just want to keep the current value in your file on the server? But have the histogram store the historical values of that value?
If so, you could use EDI, and setup a custom indicator that is just setup with syntax...
EDI
and that EDI points to your web file. Add that file to your chart (any chart really with the same symbol) and setup the CI to "Store Current Value to V#/C#". Let's say V#11
Now, create a Custom INSTRUMENT, and setup that custom instrument with a ticker like $WEB_DATA and set it up to follow V#11
Then add that custom instrument to your chart
Let me know if that works. You'll need to review this video on EDI if you haven't already...
