I Got Tired of Tracking Options Trades in Spreadsheets — So I Built My Own Tool

Source: Dev.to

Overview

Like a lot of retail traders, I started with spreadsheets.

At first, they felt fine: simple rows, some formulas, a conditional format or two. Then options happened.

• Multi‑leg trades.
• Rolling positions.
• Partial closes.
• Assignments.

My “simple spreadsheet” has transformed into something fragile, slow, and prone to errors. One broken formula, and my P&L was lying to me.

That frustration motivated me to build Optioneer—not as a startup idea, but as a tool I needed for myself.

This post isn’t about a launch. It’s about what I learned while building a small SaaS as a solo developer. In this field, bad data leads to bad decisions.
