Custom data provider

[Leonardo]

Hi,
I am from Brazil and I am very interested on the software. However I have some questions.
Please, can I use other data provider? I would like to have real time data, but I think there isn´t brazilian stocks on Tiingo. I checking on alpha vantage, but I am not sure also.
There is any possibilty to use DDE (i have DDE quotations)
Sorry if my questions are not clear, but I am not a experience user.
Thanks,
Leonardo

Please, can I use other data provider?

For EoD you can use Metastock data if you have that. But, for intraday/realtime as of now only Alphavantage is supported. We are planning to add support for more data providers and also support of Metastock format and ascii format for realtime.
Will it be helpful for you?

I checking on alpha vantage, but I am not sure also.

You can use Stockalyze itself to see if your favorite stocks are available using Alphavantage.

There is any possibilty to use DDE (i have DDE quotations)

As of now it is not supported.

Stockalyze is for everyone. Please let me know if there is anything else I can help you. Also, please let me know if support of metastock or ascii/text fle format for realtime will solve your use case?
