Does RTO and Tickhistory..both products have the ability to work entirely cloud-to-cloud via API (i.e. feed the data into client system without a desktop app)..
Can you please help with this question?
Yes. RTO is cloud hosted real time data dissemination system and is able to provide data using RSSL and Websocket protocols. Tickhistory is available in for of REST API, or as a bulk data directly into BigQuery or Snowflake.
Both these products are designed for enterprise use and do not need any desktop app.
