I'd like to have a candlestick chart that plots trade data from a websocket feed. The incoming trade data has price, volume, and date-Time.

I've looked over all the documentation and demos, but I can't find any information on how to update an existing chart data point. In my case, I need to be able to update the close field on an existing candlestick.

  • Not familiar with this library, but their API seems pretty thorough. Have you checked out their page on [OHLCCandleStick](https://www.arction.com/lightningchart-js-api-documentation/v1.0.0/classes/ohlccandlestick.html)? I'm guessing `setValues()`. – Jonathan Lam Aug 10 '19 at 19:13

  • For web socket data feeding, there's an example in Github for LightningChart JS https://arction.github.io/lcjs-showcase-trading/ It's reading data from WorldTradingData.com – Pasi Tuomainen Oct 08 '19 at 18:25
