third-party indicator

[imalil]

I have a third-party indicator which I like. The code is locked. It runs by itself on its own charts. I would like to add colored marks or symbols to the charts on which this indicator runs when certain user-defined price conditions are met--to alert me of a situation. I want the symbol to occur at the bar where the condition(s) occurred.

Is it possible for me to write my own indicator, put it on the chart with the locked indicator, have it read the price info from this other indicator and place a mark on the chart at a specific bar?

Please tell me If this is possible. If so, please link all the tutorials you can on coding this type of scenario.

Thank you.

Basically this depends on how the third party indicator is coded. If some of the values are exposed via a public property you can access the results and use them for your purposes as intended. In case that there are no public properties which hold those values you cannot do it.

The values are merely order flow, laid out in a user-defined time frame. Is this what you're talking about?

imalil, that would really depend on the study and how those values are displayed / exposed, for example plot values would be directly accessible programmatically. The best course of action would be contacting the developer of the addon to clarify how values could be accessed (and if at all).

Thanks, Bertrand. I'm waiting for the programmer of the indicator to respond to your question. In the mean time I was wondering: the values I am after are simply order flow--something readily available, do not change from programmer to programmer, and are not calculated via a proprietary algorithm. Since I paid for and use this indicator, why would I not have access to the values?

Just trying to learn. Thanks.

If you don't have access to the values, that's simply because the developer didn't make it available for you. Perhaps because you didn't request that when hiring him.

[imalil]

I didn't hire him. I bought their out-of-the-box indicator that I want to keep as is. I merely want to alert myself when a condition happens.

imalil, how would those values be visualized? Do you have perhaps a screenshot to share?

[imalil]

How do I attach my screen grab? I don't see an option.

1. Open a new reply dialog
2. Scroll down and select "Manage Attachments"
3. Click "Choose file" and browse to the screenshot
4. Click "Upload"

Now the screenshot will automatically be attached in your reply.

Thanks.

Apparently you have to click 'advanced'.

[imalil]

Bertrand, do you have any thoughts on my screenshot? Thanks.

[NinjaTrader_Bertrand]

imalil, sorry for me delay - thanks for the screenshot, looks like it's not done via plots but custom drawing via C#. I could not say if this info could be accessed programmatically or not, your best option is to work directly with the vendor / developer here to understand your options.

[imalil]

Bertrand, could you briefly tell me how plots can be be accessed programmatically and not numbers coming from the exchange?

Could you link an example of code written to read plots from an indicator?

Is there any way to convert numbers coming from the exchange to plots or something readable like that?

Thanks.
