It's Bernie Sanders' Utopia!!

Crap. Sorry about this. I just glanced at your post on my phone and thought you were referencing equities. No, Ninjatrader does not backtest options. Sorry for the confusion.

I like Ninjatrader. I find it very easy to use and I don't ever have any problems.

I remember hearing good things about tradethenews.com. Any idea how much the service is?

Can anyone recommend a good news service? I think the one I subscribe to currently is delayed and often misses big news events. What are some good news services for day trading? I did a search here for this kind of thread before and they seem to be dated. I'm not really interested in super...

Guys. Thanks. This is a huge help. I think this helps explain it a bit. I really appreciate your taking the time to respond! Much, much appreciated!

I'm not sure I understand. Can you explain this a bit more fully? Why would they be listed at all if they are NEVER the NBBO?

Sounds like you were only at the bottom of the barrel prop firms. All the ones I've been with have assumed the risk. The type of firm you are allowed to trade with is usually indicative of how well you can trade. There are indeed scams out there, but if the trader had good performance as he...

The only thing stupid here seems to be your reply. As I said, I didn't read through all the comments & only made it to page six. Based on your comment, I figured I must have been missing something and there was more to the story, so I read some of the recent comments (I started with the...
