Post From: TopstepX integration?

I’m running Sierra Chart on macOS via CrossOver and wanted to share a small solution I built, since SierraStep unfortunately doesn’t work in this setup. I also didn’t want to run a full Windows VM with Parallels just for this purpose.

So I wrote a small Python bridge that connects to Sierra Chart using the DTC protocol, reads the trade fills in real time, and forwards them as market orders to TopstepX.

Thanks for mentioning this. Following your lead, I was able to make something very similar that works remarkably well with my non-Topstep PX account. And the API fills seem to get rid of that ProjectX input lag.

Re-reading this, though, I need to go back and change my limit order-copying logic to market orders.
