Purchase once and your indicators are linked to your ATAS account. No license keys, no manual installation, no activation codes — open ATAS and they’re there.
Pay securely by card in under a minute — and tell us the email your ATAS platform logs in with.
Your indicators are granted to that ATAS account. No license keys, no files, no manual setup.
Your tools are waiting in your indicators list. Add one to any footprint or cluster chart.
Read the order flow with professional tools built natively for ATAS — nothing else to configure.
Footprint Lab exists because the studies we wanted on our own charts didn’t exist. Here’s what that means for you.
Every indicator started as an internal tool for our own futures trading. If it doesn’t survive live tape on our charts, it doesn’t get shipped.
The same logic has been running with traders using our Sierra Chart tools. The ATAS editions are native rebuilds — not quick ports.
ATAS ships excellent built-ins — we don’t resell what you already have. Every tool adds a read the platform doesn’t: sequences, micro-absorption, statistical delta extremes.
No win rates, no “institutional secrets”, no signal service. Rule-based studies that show their work on the chart — you stay the trader.
Try any indicator free for 7 days, on your own ATAS data. One-time price, no subscription, nothing to cancel.
