I can honestly say R Trader Pro just isn't gonna work for me. I'm mostly a scalper, and it just isn't as good as say TT, Jigsaw, Sierra, CQG and so on. Shoot it isn't even as good as Tradovate's buggy DOM. I think position/swing traders who don't need an easy to manipulate quick in and out DOM might find it far more useful than someone like me.

I'm just gonna stick to Jigsaw.
Finding a charting solution is now my biggest issue.

that TPO function does look nice!

I'm a fan of tradeovate. The owner who I spoke with at length knows the industry inside and out. He built one of the most early stage robust forms in the industry it is still my favorite. He also is trying to help high volume traders with zero commissions yes I know the clearing fees are a lil higher but the pipe to cme is cqg and I dont find tradeovate to he buggy and the phone app is the best in futures imo.

I use Sierra I use rhiithmic at amp and i use a firm with gain financial and the OPEC trader dom.

I do find rhithmics dom to be almost an after thought but the servers alre super fast and the owner is fully involved and top notch. Same with ninja and cqg. I would say my experiences with TT were never that great as far as service but then again they are the reason so many of us pay per trade since they sued and won for their dom being trademarked...you can find a lot of info under the trademark search and patents

I also demos optimus and I think firewire with iron beam..they are all really fast now and pretty solid.

Is there a way to manually lock trading for the day without having to set a daily loss limit?

You can use the no trading hours :

in Risk parameters set by the Trader

That'll lock one out for the day or is it easily bypassed by just changing/removing the values?
