Use Thinkorswim’s Premarket Gap Scanner to find Gap & Go Setups

use thinkorswims premarket gap scanner to find gap and go setups

Thinkorswim offers a premarket gap scanner that can be used in a multitude of ways. One of the things that it can be used for is to find gap & go setups. This might sound like a foreign concept to you. If you don’t know the ins and outs just yet, don’t worry because that’s exactly what we’re going to be talking about in this article. As such, if you would like to find out more about how you can use Thinkorswim’s premarket gap scanner to find gap & go set ups, then keep reading down below.

What Is The Pre-Market Gap Scanner?

Gaps are measured from the market’s closing price the day before to the current day’s opening price. A gap occurs when a stock opens at a higher price the next day than it closed at the previous day. However, gaps can be up or down and can occur with all stocks from all markets. 

A pre-market gap scanner is a series of scanners that are used to find the highest gapping stocks before the market opens. The gaps are important to identify as they show a sudden move by any given stock, which are often the indicator that a bigger move is coming. If you keep on top of the gaps with a pre-market gap scanner, you will be able to make better informed decisions using all the information that is available to you.

Why Use A Pre-Market Gap Scanner?

If you are closely monitoring the premarket trading activity, you are likely on the way to edging out the competition. This will help you with your day trading by providing you with insight other traders may not have. As such, you can start the trading day the right way, with all the information you need at your fingertips.

It is important for you to understand, however, that pre-market trading volume is often light, so you won’t see massive differences in the stocks. As such, when you are using a scanner, make sure that you are only looking at stocks that are trading with above-average premarket volume. This will give you the insight that you need for potential trades.

How Can It Be Used To Find Gaps?

First off, you will want to: 

  1. Run a scan, which can be done by clicking the scan button on the top of the screen. 
  2. From here, it will give you a range of defaults, but you should delete these and start over for the best results. 
  3. You can add filters to your search and one of these is ‘stock.’ If you click on ‘stock’, then change it to ‘last’ you will get a list of yesterday’s stocks. 
  4. You can set the minimum and maximum range of money for the stock price, so you can set this for the pierce range that you are looking for. The smaller the range, the less data there is going to be for you to go through. You can set this up however you want to but you’re also not going to get much from the gap scan if you set your limit too high because the percentage moves don’t tend to be there. 
  5. Once you have done this, you want to add another filter, then click on stock again. This time you’re going to be selecting the volume. Think carefully about the threshold that you want to set here so that you are getting the right data.
  6. There are of course, other filters that you can go through such as the ‘study’ filter which will give you more options to choose from. 
  7. There are also the patent option and fundamental filters for you to use depending on what you are searching for specifically. 
  8. After you have added all of your filters, click scan and then there will be a list of stocks for you to sort through. 
  9. You can add in things such as the mark percent change if you would like to filter them further which will help you find the gaps that you want to trade.

Advantages Of Gap & Go Setups

Gap & Go setups have a number of advantages which is why a lot of people choose to trade this way. The first is that it is possible to make high profits using this system. They are also super easy to identify, making your life so much easier than if you were to use one of the other strategies out there. 

If you manage to find stocks that have good volume, they will largely prove to be reliable and allow for little chance of manipulation. This means that you are getting the most out of the stocks on the market. 

The final advantage that we are going to look at is that it is perfect for day trading the market open. You want to trade at the market open or just after when it comes to gap & go setups as this is how you find the best gaps in the market. As such, if you are someone who likes to trade when the market opens as opposed to throughout the day, this is the strategy for you.

So, the advantages summed up are as follows:

  • You can see high profits
  • Gaps are easy to identify, especially using a premarket scanner like the one offered by Thinkorswim
  • Reliable information that you can use for the days trading
  • It is perfect for day trading the market open

Why Use A Scanner To Find Gaps?

This is the easiest way to find the gaps on the market. If you are going to trade gaps successfully, then the premarket scanner will search for stocks that have volume in the premarket. Every morning there are new gapping stocks that update on the pre market scanners, allowing for those people who are ready to get ready.

We hope that you have found this article helpful, and now have a better understanding of how you can use Thinkorswim’s Premarket gap scanner to find gap & go setups. Take this advice, and use this tool and you will be able to find gap & go set ups without much hassle. Good luck and happy trading!

Scanning for Gaps in the Pre-Market with ThinkOrSwim

 

ThinkOrSwim’s built-in scans don’t allow you to scan for gaps in the pre-market, they only work after the open. Because of this, most traders are forced to pay huge monthly fees for premium scanners like Trade-Ideas or Pristine’s ESP scanner. So I developed these custom scans using TOS ThinkScript to help find the best stocks forming gaps in the premarket, using the free market data and scanning tools in the ThinkOrSwim platform.

Pre-Market Gap Scan OVERHAUL!

premarket movers gap scan for thinkorswim

I want to be sure I’m providing a really good value for what I do, and that I respond to feedback from my customers. To that end, I spent a lot of time doing a complete overhaul of the pre-market gap scan set for the Stock Hacker scanner in ThinkOrSwim. To be clear, the old set of scans worked great, and I use modified versions of them all the time.  But I wanted to make the scans even more powerful and full-featured so that they really do the best job they can possibly do. So today I’ve released the new version 2.0 gap scans, and EVERYONE who has purchased the scans in the past gets a free upgrade. You’ll notice the new links in your My Account > Orders > Order Details section automatically. Also, for those that haven’t purchased a copy yet, the scans are on sale this month here.

What’s New with the Pre-Market Gap Scan

First, there are a lot more of them, and all of them are more full-featured and easier to customize. They’re also more consistently setup, with cleaner code and comments.

Second, all the scans are set to find gaps greater than a certain percentage change, and you can now change that percentage to whatever you want for all of the scans!

Third, you’ll notice some new scans in both the pre-market group and the regular hours group. In the pre-market gap scan group, I’ve included a set of scans that finds what I call “insignificant” gaps, or gaps from the close, not from the high or low. Basically just a pre-market mover stock where there’s a gap between yesterday’s closing price and today’s opening price, even if that doesn’t take the open outside of yesterday’s range altogether.

Technically, a gap is any stock that OPENS higher than the previous day’s high, or lower than the previous day’s low. But if you run regular hours scans later in the day, the stocks might not all look like gaps because some of them have already filled the gap (i.e., even though a stock might have opened below yesterday’s low, today’s trading has moved the high so that it is now equal to or higher than the previous day’s low, for example, filling the a gap down). So one or two people got confused when my regular hours scans included these stocks that had later filled their gaps. I explained it to them, but I figured it would be even better to give everyone both options so you can weed out the ones that have already filled the gap, if you want to. So you’ll notice those scans below under “regular hours”.

All Version 2.0 Gap Scans Default to these Settings:

  • Last Price Between $5 – $200
  • Avg. Daily Volume > 500,000
  • Avg. True Range > .5
  • Gap >= 1%

All these settings can be adjusted and my comments inside the scan should help you do that if needed. Just use the drop-downs and input fields, or click the pencil icon next to any filter to change it. If you want to remove a filter altogether just click the X on the right hand side of the StockHacker window for that line of the scan. Be sure to save a new copy with a new name to apply the changes.

Definitions

I always refer to gaps in terms of either being insignificant, significant, or tier 1. That’s just how I learned to think about them, but to translate my “trader speak,” here’s a quick definition of each:

  • Insignificant: A gap from the close, where the open has moved > X% from yesterday’s CLOSE, but where the stock may or may not be opening outside of yesterday’s range altogether. These are basically just a good, cleaned up list of pre-market movers, and this is the broadest type of gap scan you can do.
  • Significant: A gap from the high or low, where the open has moved > X% from yesterday’s HIGH or LOW, and thus the stock is opening completely outside of yesterday’s range. These are “true” gaps.
  • Tier 1: A significant gap in the opposite direction of yesterday’s price movement. So if yesterday was a green up bar, today is a significant gap below the low of yesterday. Or if yesterday was a red down bar, then today is a significant gap up over yesterday’s high. Basically the gap is negating all price movement from yesterday and “shocking” traders who wake up and see their positions suddenly in the red. There is a greater likelihood to see some panicked covering of positions at and near the open, and especially at any early retrace toward yesterday’s price where trapped traders will try to get out nearer to break-even.

Low Float Stocks

Just a quick note here: I know a lot of pre-market gap scan users also trade low float stocks. Low float stocks that gap in the morning can often create a real spike in price movement a make a trader a lot of quick profit if they’re on the right side of that price movement. But trading these setups used to be next to impossible to do within ThinkOrSwim, so most people had to pay for a standalone scanning service like Trade Ideas at god-awful subscription rates.

However, recently I came up with a workaround that has been doing well for TOS traders — I’ve painstakingly created 5 custom static lists of stocks, with floats less than 10 million, 20, 30, 40, and 50 million shares float each, and I have posted those for sale over here.

And it gets better. All the gap scans can be set up to run only on the low float lists, thus only returning low float gapping stocks. So now if you purchase both products in the shop area, you can not only scan for normal gaps, but also for the low float gaps so many people are looking for ways to find now.

Improvements

If you have any ideas for improvements to either the pre-market gap scan or the regular hours gap scan, I’m happy to hear them. Also, since this is a big release, I’m sure there might be a bug or two found during the first few weeks, so let me know if you spot anything weird.
