A modern, fast alternative to DAS Trader and Sterling Pro for tape reading practice.
Built with Rust and GPU-accelerated rendering. DOM ladder, time & sales, and charts all update in under 16ms — faster than legacy platforms.
Play at 0.25x to study setups in slow motion, or 10x to scan through the session. Seek to any moment with the trade activity timeline.
Full tick-by-tick trade stream color-coded by side. See exactly when large prints hit the tape and at what price levels.
