Pricing

Pricing for LightningChart JS, .NET, and Python is obtained via a quotation request rather than published price tiers; a 30-day free trial is offered for JS and .NET (7-day trial mentioned for LightningChart Trader). A related product, Dashtera, was separately advertised with a limited-time lifetime deal ($59 one-time, normally $199/year).
