This is my first post here, so forgive me if it's in the wrong forum. Anyways, I have been studying about the markets for about two years now and the time has come to begin. Since I definitely am not going to scalp trade, or trade very actively (I intend to do about 3-5 round trips a day) I don't think I need access to LII. So here's the package I consider using: Broker: Ameritrade Quotes, Datafeed, ... provider: QQL Screener: Haven't decided yet, maybe Advanced Analyzer (but no real time scanning) or something like that Why ameritrade? Since I'm not going to trade overactive, and am going to trade frequently over 5k shares a time I preferred a flat rate broker instead of a per share based one. I also don't need a direct access broker for my type of trading (I think). Now my biggest concern is that ameritrade uses Payment for Order Flow (PFOF), but is this going to be a major concern for me? Will it influence the price I get for the shares or doesn't it make such a big difference? And as for the rest, I think QQL is a reliable, cheap tool to use. What's your view, or recommendation?
