If you are reading this considering Prime Option Outlay (Imposter) - run. I wish I had read more negative reviews from a review site like this one. I thought the positive ones were real. Maybe some are. My experience over for just over a year has been so bad I feel obligated to warn others. Do not make my mistake.
Pros: Dividend tracking|API access|Customizable dashboard|Good analytical tools
Cons: Would like more payment methods|No fractional shares
