What Beta Users Say

"Caught a volume spike on NVDA at 8:45am before the gap up. Would have missed it completely without the pre-market scanner."
— @tradesmart_x · Beta User
"The sector rotation signal fired on XLK before tech ran 2%. This is exactly the edge I was looking for."
— @optionsflow_daily · Beta User
"Finally a platform that shows me what Berkshire and Citadel are actually doing, not what CNBC says they're doing."
