How the Trade Ideas Stock Scanner works

A stock screener is your fantasy football lineup. You set it before the game. A stock scanner is the game once it has started, while the plays are happening.

Trade Ideas Streaming Alerts are the scanner. They can fire on every trade. That can be multiple times per second. You do not refresh a list.

Seeing a setup as it happens is a big advantage for active investors looking to apply capital. If you are okay with static non-refreshing data, Trade Ideas is probably not your best choice.

Ask Holly in plain English and it builds the alert for you.

Or use the configuration screen. Pick the alert, set the filters, and it runs. 310 alerts and 249 filters ship with the product, and our help documents each one.

Trade Ideas Stock Scanner questions

What is a stock scanner?

A scanner watches trades while the market is open and reports the stock the moment it matches. A screener is the lineup you set before the game.

Does Trade Ideas have a real-time stock scanner?

Yes. Trade Ideas Streaming Alerts are the real-time stock scanner. They can fire on every trade, and that can be multiple times per second. You never refresh a list.

How do I make a scan?

You can start with a ready-made channel on the Channel Bar. When you want your own, ask Holly in plain English, build it on the configuration screen, or write the filter in the Formula Editor.

How do I scan for stocks making 52-week highs?

Turn on the New High alert (NHP) and set its minimum-days box to 365. It then fires only on prints above the past 52 weeks of prices. The New Low alert (NLP) works the same way for 52-week lows.

How do I scan for stocks making 30-minute highs?

Turn on the 30 Minute High alert (IDH30). It fires the first time the current 30-minute candle trades above the high of the previous candle. The 30 Minute Low alert (IDL30) works the same way for 30-minute lows.
