Why this is a gap
Surfaced from a high-intensity complaint with clear willingness to pay and a specific, reachable audience.
The market
Retail traders tracking performance systematically need frictionless logging. 140 monthly searches suggest steady, niche demand from traders who prefer spreadsheets over dedicated platforms—small, loyal cohort but not explosive growth.
Competition & the opening
Competition 1/10 means no purpose-built spreadsheet journal exists. Dedicated platforms (Edgewonk, Tradervue) exist but traders resist tooling; spreadsheets are familiar. The gap is a lightweight Sheets automation that logs trades with minimal friction.
What's hard to build
Building requires reliable data sync between broker APIs (Interactive Brokers, Thinkorswim) and Google Sheets, plus formula logic for P&L and metrics. Feasibility 7/10 reflects that APIs are documented but maintaining real-time sync without quota overages and handling edge cases is labor-intensive.
Why now
Traders manually log trades in sheets; AI can auto-extract from broker feeds and generate journal entries to save 3+ hours/week.
