I have several machines with Steadfast. You can check them out.
GPU is worthless, NinjaTrader does not use CUDA or etc for backtesting. The only platform I know of that does is Matlab, and perhaps R.
Amazon cloud service is not going to help you in my experience, due to the way the threading works. Your best bet is to lease a dedicated server from a hosting company. But "don't feel like getting a new computer" is really the wrong approach, in my opinion. The best use of your time and money is likely to upgrade your existing computer.
Due to time constraints, please do not PM me if your question can be resolved or answered on the forum.
Need help? 1) Stop changing things. No new indicators, charts, or methods. Be consistent with what is in front of you first. 2) Start a journal and post to it daily with the trades you made to show your strengths and weaknesses. 3) Set goals for yourself to reach daily. Make them about how you trade, not how much money you make. 4) Accept responsibility for your actions. Stop looking elsewhere to explain away poor performance. 5) Where to start as a trader? Watch this webinar and read this thread for hundreds of questions and answers. 6) Help using the forum? Watch this video to learn general tips on using the site.

The following 2 users say Thank You to Big Mike for this post:
1. GPU/CUDA processing aside, my task manager shows all 4 cores cranking around 80% when I initiate GO (and back down to single digits when run is complete). This would seem to suggest multi-threaded (parallel) processing, no? Or is my understanding of parallel processing lacking?
2. I may be behind the curve as I am just discovering strat optimization, but it looks like interest here died on the vine 2 or 3 years ago. Same in the NT support forums. Did I miss something? Has optimization been debunked? Are the tools available to retail traders just not worth the time and effort? If not NT, PH and MOGO tools (which don't seem to have been updated for years), then what have traders moved on to?
