External program drawing object on chart

[roland_nt]

I have a third party program which uses the Ninja Trader API to submit enter long or enter short orders using the API.
I would like to plot a diamond on the NT chart at the same time as the order is submitted. Is there an API reference sample for external programs to access a chart.?

If there is not, I could alternatively make an indicator which would be loaded into the chart which indicator picks up a value from the third party program and uses it to derive the place to place the diamond. A crude way would be to have the third-party program write the data to a file which file is periodically inspected by the indicator. This seems crude, however

So is there any other way for an indicator to capture a value from a program ruining separately from NT?

Hello,

Thanks for the forum post.

Unfortunately there is no supported way for the API to access a NinjaTrader drawn chart. You would need to code an indicator that adds these symbols to the chart manually as you describe.

Let me know if I can be of further assistance.

use DDE to pick up external program data

Is there a way to uses DDE or some other mechanism to communicate on an interrupt basis with an external program? Some thing like the OnBarUpdate() architecture but having a way to pick up external data - for example (made up name) OnDataTrap()

Hello,

There is unfortunately no DDE connection supported in NinjaTrader however you may try searching the forum there have been a few members that have tutorials on how to add this into NinjaTrader.

Let me know if I can be of further assistance.
