ATAS Indicators – Order Flow Toolkit With a C# API
Last updated August 5, 2026
ATAS ships with 300+ indicators tuned for futures order flow. You also get a full C# API so any custom logic — delta filters, cluster scanners, VWAP variants — can be written and plotted natively.
Most-used order flow indicators
- Cumulative Delta & Delta Divergence

Writing your own indicator in C#
The ATAS Indicator Editor exposes OnCalculate, ClusterCollection and the tape stream. If you can express your idea as "when delta on the 500-tick chart crosses +2000", you can automate it in ~30 lines.
