Intraday Alerts At Overnight Highs and Lows
A quick Google search on the term “Overnight Range Trading Setups” nets some very interesting results. So I spent some time writing code and looking at charts. I think there is some real evidence to support the inclusion of the overnight range in your trading setups. I’m not here to show you how to trade the overnight range. However I did build you the best tool I can dream up, given my current knowledge and experience. The rest is up to you.
In this video named Thinkorswim Overnight Range Scan Alert, we show you many examples of how this tool may be applied. In addition to some special levels, we also include the ability to build custom scans based on its signals. As if that wasn’t enough, we throw in a bonus by showing how you can generate real time alerts based on the scan results. I am really excited to be able to present this material. I think this may end up being a valuable tool for many. It was a real eye-opener for me.
The code for the scan is included at the very bottom of this post. So be sure when you are done watching the video to scroll down past the video to get to that code. In the video we show you how to use that code to build your own custom scans, with alerts!
