What each column means
- Day % and 5-day %: the change from the previous close, and from the close five trading days ago.
- RSI 14: the 14-day Relative Strength Index with Wilder’s smoothing. Under 30 is often called oversold, over 70 overbought.
- vs MA 50 / MA 200: how far the price is above or below its 50 and 200-day simple moving averages. Above both is a common definition of an uptrend.
- Volume ×: the latest day’s volume divided by the average of the 20 days before it. 1.5× or more is highlighted.
- From 52w high / Above 52w low: the distance from the highest high and lowest low of the last 252 trading days.

Frequently asked questions
Is this screener free?
Yes. There’s no account, no subscription and no limit on scans. Crypto and crypto perps need nothing at all; US stocks and CME futures need a free data key of your own, which takes a couple of minutes to get.
Which markets can it scan?
Four, picked with the Market buttons above the table. Crypto (the default) scans the 250 busiest USDT pairs on Binance. Crypto perps scans the 200 busiest USDT perpetual futures on OKX. Both are free public data and need no key. US stocks scans about 600 US stocks and ETFs with your own free Alpaca key, and CME futures scans about 25 front-month CME Group contracts (stock indexes, Treasuries, oil, gas, metals, grains, livestock, currencies and CME bitcoin) with your own free Massive key.
Why do stocks and futures need a key?
Stock and futures prices are licensed data, so a website can’t hand them out for free. Alpaca (for stocks) and Massive (for futures) give anyone a free data key. Your key is saved only in your browser and sent only to that provider. See how to get a free Alpaca key and how to get a free Massive key for futures.
Which stocks does it scan with an Alpaca key?
About 600 US stocks and ETFs: roughly the S&P 500, popular growth and momentum names, and around 75 of the most traded ETFs. The largest 135 load first; the rest follow automatically a few seconds later.
Is the data real-time?
Crypto and crypto perps are live from Binance and OKX, on daily candles that start at 00:00 UTC (today’s candle is still forming). Alpaca’s free stock data is 15 minutes behind the market, and Massive’s free futures plan is 8 hours delayed. Turn on auto-refresh next to the results to update the table in place every 30 seconds, minute or 5 minutes.
