Hi
I am new to forum and am looking for examples on how to use Zorro with brokers who only support web based trading

You have two three options:

1) Use a supported broker.
2) Make your own broker DLL. You must know/learn how to program.

To write a DLL, it's best to have an API to work with, such as a REST API. Whereas, to program mouse clicks into a web browser is not fun.

3) Do what Petra says, below.

The keys function can send mouseclicks to a web browser.

Re. keys(), beware that it sends to the active window. In practice this is not a very workable long-term solution, even on a dedicated machine where you may think you have total control over keeping the browser window always as the active window.

For want of a keystroke ...

Yes, Zorro seems to always be the "active window".

No, the active window is always the last started or last clicked.

For actvating it by script, use SetForegroundWindow. Do not work on that PC at the same time, or else your mouse clicks will be in conflict with the automated clicks.

Just starting with Zorro, I found this article with an example code of using an online broker.
