PremiumFlow – Brokerages calculate options cost-basis wrong

Hi HN,

I’m the developer behind this. I built it because I realized my brokerage account (and my spreadsheet) was lying to me about my profitability.

The Issue: If you trade the "Wheel" strategy or sell covered calls, you know the pain: you collect a premium, the stock drops, and you roll the position. Your broker shows a loss on the trade, but doesn't account for the 4 months of premiums you collected that actually lowered your break-even price.

My Fix: I wrote a custom engine that links these "rolled" trades together into a single campaign.

Real Cost Basis: See your actual entry price after all premiums.

Capital Efficiency: Calculates annualized return on risk (RoR) so you know if the capital lockup is worth it.

Privacy: No bank connections required (yet)—just import or manual entry.

It’s a solo project, not a VC-backed startup. The free tier lets you track active campaigns.

I’m specifically looking for feedback on the Dashboard UI—is it too dense, or do you prefer seeing all the Greeks at once?
