Many times we forget that there are multiple dimensions to the stock market — price, share volume, and tick/trade volume all play a role, but one dimension we often forget about is the dimension of time. In our stock charts, time is one of the two dimensions displayed … price is the vertical axis, and time is the horizontal axis. But we often seem to ignore it.
Time even influences the movement of markets due to a wide variety of reasons. Tom Bulkowski’s statistical work has shown that intraday trend reversals tend to occur at 1 minute past each hour, 1 minute past each half hour, and 51 minutes past each hour (examples would be 9:01, 10:31, 11:51 respectively). Knowing these kinds of statistical tendencies is what having an edge in the market is all about. There are also exchange procedures that lead to price movements at certain times of the day — for instance, intraday margin calls usually happen between 11:00 a.m. – 1:30 p.m. Things like this show how time truly matters to price movement, yet is largely ignored.
It was with this in mind that I put together a highly-customizable ThinkScript indicator to highlight important times throughout the day. It can be used to highlight statistical reversal times you’re watching, to tell you at what time of the day you should change strategies, or even just remind you to take lunch or close out your afternoon positions. There are endless ways the time lines indicator can be used based on your own trading system.
Customizable features include:
- The ability to add custom text labels to each time line, or remove individual labels
- The ability to show/hide particular times (just place a zero in the time specification field to make it dissappear)
- The ability to change the line color
- The ability to change the line style (solid, dashed, dotted, etc.) and thickness/weight
- The ability to place the lines on the lower studies (volume, etc.) as well as the main price chart, if desired
Hi guys, I’m Josiah, and I’m a trader/programmer from the Nashville, TN area. I recently finished up both a bachelor’s and a master’s degree in Computer Information Systems at a local university and have been self-employed since then, trading and developing projects with Ruby on Rails on the side. Since I was already familiar with a certain amount of programming, and had an active interest in trading and investing, learning ThinkScript — the scripting language for the ThinkOrSwim platform — made a lot of sense, and helped me develop a platform configuration that really streamlined my trading workflow.
About the ThinkScripts
These basically came about because I got so frustrated with the limited built-in capabilities in TOS, and standalone subscription services that charge $99+/month. So I decided to learn ThinkScript so I could develop indicators and scans for myself. I still use most of these thinkscripts every day while trading.
