I'm writing my own trading software and rather than signing up for oodles of demo accounts and sifting through them, I thought I'd ask what features actual traders love/hate about their platforms (yes, despite the fact that this is ET, you will be given the benefit of the doubt if you reply. ) I'm looking for those little cool features that really make a platform shine and make you say: "damn, I can't live without that." Things that I know that are cool already and will have: 1) DOMs 2) trading on an actual chart. If you don't care to go in to nauseating detail, simply direct me to a particular website and say: "Go! Fetch!" Platforms I'm grabbing from currently: Ninjatrader/Xtrader (DOM) Ninjatrader (Charting) I'm gearing this toward futures (ES, YM, CL), since those are my primary vehicles of interest. Thanks for your replies. And yes, I may be re-inventing the wheel, but it'll be MY wheel!
