Can anyone point me in the direction of an indicator that plots supply and demand zones for tradestation? Don't feel like paying 20$ monthly for one that doesn't even capture all the zones.

Hawkeye makes a zones indicator, which I believe they license from APA zones. I've just written to them to ask if it works with trade station 10, but I haven't gotten a response yet. I'll post here when they respond.

Did you ever get the indicator and if so do you find value in it?

I woke up from my indicator purchasing madness, and just drew the damn zones myself honestly. The easiest thing for this is the Extending Rectangle Tool, which is included with SierraChart, my current platform.

Think about it, drawing your own zones means you're taking a deeper look at the price action that made up that zone, so you have more context which should help your trading. Plus, sometimes it's not clear what is a zone or isn't and this is where your interpretation and understanding of the market come in, ie: you may grab a zone that an indicator wouldn't.

Hope this helps
