Here’s how to scan for day stocks that are making big price moves AFTER the open. Big movement during the day, not overnight gaps, is how day traders make money.
When I started day trading full-time, back in 2005, I would sometimes look at the top % and $ gainers/losers list available on many financial websites. Occasionally this list would yield a couple of good day trading candidates, but quite often the move was already done. The stock had gapped up or down in the pre-market and wasn’t doing much during the day.
I developed the “during the day scan”, discussed below, to find stocks that are moving well after the open. To a day trader, a big gap means nothing if you can’t trade it. So my goal is to find stocks that are on the move after the open, when I can actually take advantage of those price movements.
With this method, the stocks you trade will likely change daily. You will need to pay for scanning software with this approach.
I use Finviz Elite, as it provides real-time scanning, pre-market scanning, and loads of other features.
Daily scanning means more jumping around between stocks (which may require more chart windows and computer monitors). This is in comparison to another approach where we trade the same stock(s) all week based on their consistently big movement. Either approach is fine, it is just a matter of personal preference.
Here’s a brief rundown of how I scan using Finviz Elite for stocks that are making big moves during the say. You could likely use other scanning software and input similar criteria.
How to Find Day Stocks Moving Big AFTER the Open
The following chart shows the criteria I use. These criteria apply to the pre-market or the first few minutes of trading. Once the market has been open for a while, keep increasing the Current Volume (starting at 100K) every half hour or so. By the end of the day, it should be Over 2 Million. This keeps out low volume stocks, and keeps the list smaller and manageable.
Set Auto Refresh to 10s (10 seconds), so the list updates automatically every 10 seconds with new data.
For Industry I have selected Stocks only (no ETFs). Get rid of that parameter if you want ETFs on the list as well—this will make the list quite a bit longer.
Set a Price range if you prefer stocks in a certain price area.
Set Average Volume to over 2 million (2M). Adjust based on your preferences.
If you want to limit the exchanges you trade, you can select which exchanges to include in the Exchange option. For this scan, I have included only NYSE and Nasdaq.
Relative Volume means only show stocks that are moving more than 1.5x usual volume. We want big volume behind the big price moves. If a stock is making a big move on low volume, that move is more likely to falter or fizzle. But if there is a big price move and big volume, the strong price action is more likely to sustain itself.
- On Finviz, Relative volume is being calculated in real-time. For example, if average volume is 100K in the first 5 minutes of the day, and today volume is 150K in the first 5 minutes, Finviz will show that as 1.5 relative volume. Relative volume is updated constantly against the stock’s typical volume up to that point in the day.
Sort by Change from Open. You can change the columns by clicking the Settings button—near the top right of the page— and picking your own column headings.
For a day trader, Change From Open is more important than Change (which is the change from the prior closing price) because day traders don’t hold positions overnight. We only care about how much a stock is moving today; we don’t care about how far it is from yesterday’s close. The price could gap 10% between yesterday’s close and today’s open, but unless that stock is moving big after the open, there is no money to be made there. We are looking for movement NOW, not overnight.
Here’s another example, from another day, taken just before noon EST. Notice how I have increased the current volume to over 500K because it is later in the day (in this case, every stock on the list has volume over 1 million shares).
The example shows many stocks that have moved more than 5% after the open.
What to Focus on and Refinements
Focus on trading the stocks at the bottom and top of the list. These are the stocks with the biggest changes from the open, both to the upside and downside. Go through some of the ones at the top and bottom of the list, and watch for trade setups. For ideas on how to enter and exit day trades, see How to Day Trade Stocks with a Trend Strategy.
Also, watch for stocks that are moving toward the top or bottom of the list from the middle. For example, a stock may only be up 1% on the day, but then you notice it up 2%, 3%, 4%…it goes from the middle of the list toward the top (or bottom, because it starts selling off aggressively). Check that stock out!
You also may notice a stock at the top or bottom of the list move towards the middle. This may also be worth checking out. If a stock is up 10%, then 8%, then 6%, that stock is falling quickly. You may want to get in on that declining trend.
If the list is too long, increase the Current Volume or increase Relative Volume from 1.5 to 1.6 or 1.7.
You can also add another variable on the Technical tab. Set Average True Range to Over 0.25 or Over 0.5. This means that the stock moves on average at least $0.25 or $0.5 per day. Since we want movement, this is a good way to make the list a bit smaller and more manageable.
The Biggest Stock Movers, AFTER the Open
This is how to scan for the stocks that are making big price moves, with volume, after the open. I find this scan much better than just looking at the “biggest percentage gainers/losers” or biggest dollar gainers/losers” lists available on many sites. As mentioned, the biggest gainer may have gapped up 20% but has done nothing since.
This list shows the stocks that are moving big right now…that are making big moves AFTER the open.
Keep an eye on the top and bottom of the list, when sorted based on Change from Open. Also, keep an eye on stocks moving toward the top/bottom of the list, or stocks starting to move away from the top/bottom of the list toward the middle. These all could signal stocks on the move right now.
