If you're just buying a computer to run a trading platform, especially DAS, you don't need to go over the top with a computer. DAS in particular is very lite on the system. You might want to check out the discord server if you haven't signed up already. There's a swing channel there. https://bearbulltraders.com/go/discord/

I would suggest 1-3 strategies overall. If you only have one, then you may miss a lot of opportunity, but if you have more than 3, you end up seeing things everywhere and a lot of it can be tricking you into taking a trade. Give each strategy a little time to see if starts feeling good to your personality and develop that with your own set of rules. All about finding what works for you personally.

Look at ProRealTime. I'm starting to get into it and liking what I see. You can get down to 1 second and tic charts as well. Also, seeing fast patterns is one thing. Being able to get filled by IB fast enough to exploit those patterns might be a larger problem.

But wait! There's more! @Alastair @peterB I actually do have a hotkey that will place down R levels. It's a bit of a hack but it works! And being such a visual person, these are a godsend for helping me get to my R goals. The way it works is if you are in a position with a stop loss set, it utilizes your SIM account to place the target levels at 1R, 2R, etc. Look below - the green arrow is obviously my entry, and the blue arrow is my stop loss in my live account. And then when I hit the hotkey it will place two orders at 1R and 2R (orange arrow) with 1 share using my SIM account. Basically it does the math calculation for 1R and 2R, swaps the montage to my SIM account, places the orders, then puts the montage right back to my live account. The 1 share orders never get filled (I'm actually not sure why...), so as the price gets to the 1R and 2R markers you can take a partial or full exit, and it will be executed in your live account. After the trade is done just cancel the orders.
