Lots of good responses here. I still haven't made up my mind. Over the yers, I've spent literally 10's of thousands of dollars on various software packages. Then I met a guy who not only is a fabulous trader, but a great coder. He was writing fully automatic trading programs before they were a thing. He managed money (mostly his and some family members) with the automated stuff and had good success. He wrote a set of great visual stuff based on his personal trading style. Great for both, scalping and swing trading. Certainly not the Holy Grail, but the best that I've used, for my style of trading, which is scalping ES, NQ, CL, ZB, etc. Best of all, it was free because we became friends over the years.
NT demo was good, but it did seem like there was a very slight delay when I hit buy or sell. NT guy I spoke with was a good guy and straight forward.
With AMP's demo, it feels a lot faster, but then, it's a demo, so all of this talk is pretty meaningless until it's LIVE, then it becomes the real deal holyfield. I'm not sure I want to be married to one platform, so I'm torn. I've been around this business for a long long time. I've heard it all, the good, the bad, the ugly, and so on. I always listen carefully to other's opinions. I still don't know what I'm going to do. Hearing that NT8 bogs down, doesn't help, but they must be doing something right, they have a lot of customers. I don't seem to see as much talk about AMP on the forums, but I can tell you from experience, their customer service guy, "Johnny" is faster than a speeding bullet when it comes to answering questions or logging into my screen to help me with an issue. He's amazingly fast and very good at his job.
I appreciate the time you each took to comment. I'll let y'all know when I decide.
