External indicator without Input serie

[FernandoParra]

Hi guys, nice to talk again
I don't know if my title really reflects what I want to do or my doubt but I'll try to explain it here, I was developing for a while an Online copy trader, I created it as an indicator and basically what it does is that I have a server, a PC on which I operate, and I have different PCs that receive this information, process it and execute it, up to there everything is perfect, now I'm trying to implement different automatic strategies on my server, but now with different markets, my main idea was ok can I add the copy indicator to each chart and it will receive the information and execute it, but I discovered that it doesn't work like that, unless I'm in the instrument chart it doesn't do anything if an order is sent to ES and I'm standing on the NQ chart it doesn't execute the order because it says that the serial input is NQ, what I want to know are two things is there a way for all the indicators to be active at the same time? Or second, is there a way to create an indicator or external chart that does not have a serial input linked to it and is simply connected to the account and communicates with the account for orders?
Sorry, I know it's a lot of text, but I tried to explain myself as best I could.
Thanks TGT

Hello FernandoParra,

Thank you for your post.

You can use AddDataSeries() to add an additional data series to your indicator.

You can also place orders directly to the account using the AddOn approach.

Hello Fernando,

Yes. AddDataSeries() calls are hard-coded, so you'll need to change the rollover date manually.
