Thank you for your question!
We have an FAQ on this topic here: Does SciChart support technical indicators.
Q: Does SciChart support Technical Indicators like MACD, SMA, EMA?
A: Our charting library lets you plot any data in the formats Line, Scatter, Column, Mountain, Banded-area (plus many more). We don’t provide technical indicators to generate the data. For this, you can either write your own, or use a third-party technical indicator library such as the open source TA-Lib (C++) or Trady library (.NET).
It then becomes a simple exercise of plugging the outputs of the Technical Indicator library into SciChart’s DataSeries
