What Otta Charts gives you
Trend Stage

Breakout from base
Tight consolidation under resistance with improving price structure.

Actionable on confirmed breakout above resistance
Generated from your ruleset logic, not Otta Charts' opinion.
Your rules. Not ours.
Most tools give you black-box signals. Otta Charts runs your framework — Stan Weinstein stages, your own momentum criteria, anything you write — on the chart you're already looking at and returns the same structured format every time.
No opinions. No recommendations. Just your system, applied consistently.
Apply the same logic to every chart
Reduce emotional overrides at scan time
Compare setups in a repeatable format
Know when a chart is actionable and when it is not
