The engine powering our stock scanner, stock screener and AI Signals
The alerts are only what you see.
Live market data feeds a proprietary event engine that powers Streaming Alerts (the scanner), Top Lists (the screener) and Holly AI Signals. OddsMaker tests the same events.
Named to the Inc. 5000 list of America’s fastest-growing private companies six years in a row (2017–2022).
Under the event engine sits a proprietary database that Trade Ideas designed and custom-built from the ground up. It is the base the engine runs on: live market data comes in, and the engine works from that database to spot each event as it happens.
We have kept modifying and improving it for more than two decades. Every one of the 310 alerts and 249 filters in our help is computed on it, so the Top Lists that refresh every 15 seconds and the Streaming Alerts that can fire on every trade share one in-house foundation.
In the pipeline above, this is the Proprietary Data Engine step. It is also where the closed loop below begins.
Most scanners wait on a static condition. Trade Ideas watches for what just happened and shows it to you while it still matters.
Seeing an event 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.
Trade Ideas also monitors unusual options activity across all stocks, with a dedicated channel in TI Pro and in the browser-based Web Dashboard.
Define the event once. Test how it behaved in the past. Then run the live alert on that same definition, so what you trade matches what you tested.
Holly uses the same live event stream as the rest of Trade Ideas. Describe a scan in one sentence and she builds the Top List and Alert window for you.
Scanning is only the first use of the data. The same stream feeds a cycle that measures, tests, tunes and selects strategies, and each trading day’s data starts the next turn.
Steps marked TI Premium run inside OddsMaker and Holly AI Signals, which both come with TI Premium.
Data and measurements. Live market data lands in the custom database described above, where it becomes the analytical variables behind every alert and filter. In the Formula Editor you combine those variables with math, Boolean logic and if-statements into derived measurements of your own, saved as custom filters that scan like the built-in ones.
Strategies and testing. Alerts and filters, yours included, come together as strategies, which you can save and reload from the Strategies tab of an Alert window. OddsMaker tests a strategy against recent market history, and its Optimization tab breaks the results down by time of day, price, symbol and each filter’s values, so you can see which settings to keep.
Nightly selection. Holly runs the same cycle on her own library of strategies. Each night she backtests and optimizes them, then picks the ones that will trade in the next session, and the morning list appears in the AI/Holly Strategy Window. During the session those strategies produce Holly AI Signals, and that session’s market data feeds the next night’s run.
Past results, including backtests, don’t guarantee future results.
Trade Ideas runs live market data through a proprietary event engine. Instead of taking snapshots of a static condition, it watches what just happened, such as a VWAP cross, a volume acceleration or a new high, and surfaces it while it still matters. Streaming Alerts, Top Lists, OddsMaker and Holly AI all work from that same event stream.
It is a proprietary database that Trade Ideas designed and built in-house, and it is the base the event engine runs on. It has been modified and improved continuously for more than two decades. Streaming Alerts, Top Lists and every alert and filter in our help are computed on it.
Yes. Streaming Alerts can fire on every trade. That can be multiple times per second. Top Lists update every 15 seconds. If you are okay with static non-refreshing data, Trade Ideas is probably not your best choice.
Nasdaq Basic is a best bid and offer plus last-sale product, a cheaper feed built for quote and chart products. Trade Ideas builds its events from premium exchange data instead, so the engine can see what just happened on the tape.
Yes. Trade Ideas monitors unusual options activity across all stocks, with a dedicated channel in TI Pro and in the browser-based Web Dashboard. Top List filters for options volume, call volume and put volume let you screen for it too.
Quant funds and institutional desks can license or access the proprietary market-data and event engine as a high-end raw or research-grade feed. It is the same infrastructure that runs the trader desk.
