How to choose the cheapest platform for you
Price only means something against what you would otherwise buy twice. A charting subscription plus a separate GEX or flow tool often costs more than one platform that has both.
If you only draw on charts, a free plan or TradingView Essential is enough. If you trade options and want to see where dealers are positioned, a platform with built-in GEX saves a second subscription.
Start on free plans. Every platform here has one, and a week of real use tells you more than a feature list.
We make Obelion, so read our view with that in mind. Competitor prices come from their own pricing pages on the date above and may have changed.
