Depending on how many hits you get, you can begin increasing or decreasing m. Any points x for which c_m(x) is positive are candidates for a local min/max. Now, begin computing curves of the form c_m(x) = |f(x) - g(x)| - m * h(x). Additionally, make a curve h(x) which gives some measure of the variability of data in the sliding window which you use to compute g(x) (standard deviation should work fine if you're using a few points from the interval). Call this curve g(x), and your original curve f(x). There are lots of different ways you could think about doing this (to remove statistical outliers, or to use more or fewer points in the window). Next, using a sliding window of size dx, generate a moving average curve corresponding to your curve. This is conceptually similar to the idea of smoothing your data. In your figure, if you take this to be too small, you will get false positives from the bumps. Here's just an idea, sort of an idea from a different angle, and possibly a very bad idea, but since differentiation isn't working, something like this might be a thought.įirst, you need to determine a minimum meaningful X-axis interval. I attached 2 pictures of the output (1st derivative and n points min/max) This works fine (not ideal), but it's lagging. I tried a second method of adding a point when dy/dx turns from negative to positive, which also creates too many points, maybe because I use EMA of tick data (and not of 1 minute closing price)Ī third method is to divide the data set into slices of n points, and to find the minimum and maximum points. I get too much or too little points - depening on I don't get the real turning points, I get something close. ![]() I create a second chart for the turning points.Įach time the dy/dx is between and - I add a point to this chart. ![]() I use the EMA20 of tick data for smoothing the data set.įor each point on the chart I get the 1st derivative (dy/dx). Andrew Burnett-Thompson using the centered five-point method, as explained here. Tried differentiating the smoothed price set, with the help of Dr. My goal is to find the turning points in stock price data. It’s eerie because the ‘room’ is quiet, but it’s also empowering to see good questions arise, humor stay present, and students be able to help each other.This question is a continuation of this one. During this transition to synchronous learning, Turning Technologies’ applications enabled me to be responsive and handle student concerns. Poll over top of web pages, videos, documents or any application, and display results instantly. Use anywhere polling to ask interactive questions on-the-fly with a floating toolbar and send results directly to your online account. A streamlined user interface makes it even easier to create content and poll participants. Our light PowerPoint add-in lets you collect results online while enjoying our industry-leading native PowerPoint integration. This is ideal for asynchronous learning and assignments, and can also be used for surveys. Share interactive content at any time without the need for a live polling session. When polling through your TurningPoint account, questions can be asked online through a computer, tablet or even a smartphone. (NEUCO) Easily poll onlineīuild and facilitate content online for a completely web-based live polling experience for both in-person and remote environments.

I understand how hard it is for these guys to sit in class and learn something new, and then say, ‘Oh, by the way, now you’re going to be tested.’ TurningPoint is fun and it gets them really well prepared. Read on to learn more about the capabilities offered by our web tool and how you can use them to improve learning and engagement in your classes and training sessions. Our web-based platform allows participants to respond from anywhere with their own cell phones, tablets or computers! Hardware clickers are also an option for in-person sessions. Create content, conduct polls and manage results entirely online while supporting remote and in-person learning.
