Trade Ideas was founded in 2003 by a group of financial technology entrepreneurs in response to the growing demand for DIY investing. The customized server-based technology connects directly to the exchanges, enabling it to track every single stock and ETF that's traded. Every tick is analyzed and tested, measuring a securities behavior against the past in real time. That's the kind of edge that day traders need.

Traders also have access to a live trading room, real-time streaming trade ideas, and simultaneous charts. Trade Ideas connects directly to online brokerage firms such as E-Trade to allow traders to move between simulated trading and real-world trading.

As you might expect, having access to proprietary, high-end technology doesn't come cheap. But $228 a month is a worthwhile investment for the edge that traders seek. A standard plan is available for $118 a month without full access to AI technology, and a further discount is available if you pay annually. A third, baseline option called TI Strength Alerts for $17 a month gives you five new trade ideas every Sunday. If you still aren't convinced about the service, Trade Ideas now offers a free version that can be used to test the pre-built layouts, scans, and screeners. However, as you develop as a day trader, you might also outgrow the free version. If that time comes, you will have the ability to upgrade anytime.

FINVIZ's stock screener has been a popular choice for investors since it was created in 2007.

Stock Rover was founded in 2008 by software engineers who have a passion for investing. They created an advanced web application to simplify how investors can research, select, and track investments. Its platform offers almost 500 screening filters for financial indicators for screening and comparing stocks, ETFs, and mutual funds. Users can finetune their results by creating complex equations and combining multiple filters. 

Investors love Stock Rover's rating system, which scores securities on a scale from 1 to 100 in several categories. These include growth, valuation, efficiency, financial strength, dividends, and momentum. Followers of Warren Buffet will especially like the preset fair market value and margin of safety screeners.
