Has anyone had any experiences with Guardian Trading? I can't seem to find any decent reviews on them. I'm comparing them against Lightspeed, Cobra, CenterPoint and IBKR Pro. They offer Das Trader Pro/Sterling. Some standout features, - up to 500k shares/mth = 0.0029/share min $1.99 (Others start at 0.004-5 share $1 min). - owned by Velocity Clearing LLC - commissions rebate includes data and software. (Others do not include data) Das Level 1 includes Das Trader Pro plus basic datafeed (market indices, nasdaq L1, nyse tape A/B). $199 comm/mth - extensive short locates. Not sure how it compares to others.
