I am a user of the NinjaTrader trading platform. As a techie, I’m also interested in the open nature of that platform to develop my own software to work with it. As part of that experience I developed a Cumulative Delta indicator to help me understand the data behind such an indicator as well as the development process. It is fully functional, efficient, and provides results almost identical to the commercial variants of such indicators. My reason for posting here is 2 fold. 1, it will encourage me to develop further iterations of software for the platform, and 2, I could not actually find such an indicator freely available anywhere without payment. (Note – I’m not averse to paying. The commercial one per the example below is one I subscribed to for a couple years from a popular vendor, so don’t think I did this because I am cheap :)).<\/em>\u00a0 Given this is a fundamental of the sort of trading I do, I thought I would share it freely in case it is useful to others.<\/p>\n

Here is a screen shot of the original indicator in use on the ES. It is the first indicator in the image. The second is a commercial cumulative delta indicator for comparison. (please note I have since updated the indicator and new screen shots are below, further down the page)<\/p>\n

There are 2 plots on the indicator. The Total and the Per Bar total. The line is red or green depending on whether delta is rising or falling during that period.<\/p>\n

One nice thing about this indicator is that it will work with historical data rather than real-time only, per the indicator supplied with NT. This is because it uses the up-tick\/down-tick method to calculate data, NOT bid\/ask in real-time.<\/p>\n

There are options to plot the session total, per bar total, or both (both are on by default). You can also choose whether to reset the total at the start of a new session, or have it accumulate (it resets by default).<\/p>\n

UPDATE 2016.10.03 – Full details below in the updates section, but some screenshots with some of the newer features below. Some of the really new stuff NT8 only, but some were present in the latest NT7 version<\/p>\n\n\t\t
