If an entrepreneur "adopted" this product today, here's the realistic math.

Fermi summary

If you convert 200 paying devs at $190/yr average, that's $38k ARR - but with a negative EV year 1 after investment and a market ceiling around $110k, this is a lifestyle side-project, not a venture.

probability-weighted, after investment

Go-to-market motion

SEO targeting 'lightweight charts drawing tools/indicators' + npm/GitHub discoverability + direct posts in r/algotrading, fintech Discord servers, and dev Twitter → $49-$199 one-time license or $29/mo subscription.

Key risks

TradingView's Lightweight Charts roadmap could ship native drawing tools (plugin already announced), instantly commoditizing the core value prop
The real paying universe may be only 300-800 developers globally - devs building serious trading platforms use TradingView Pro embedded, not Lightweight Charts, so buyers skew toward hobbyists with low willingness to pay
One-time license model creates a revenue ceiling that resets annually; without SaaS recurring billing the ARR metric is misleading and compounding is hard
Free GitHub alternatives (open-source indicator libs, community forks) are the default expectation in developer tooling - charging for what peers give away requires strong DX differentiation
