Check out the new article: Developing a Replay System — Market simulation (Part 05): Adding Previews.
We have managed to develop a way to implement the market replay system in a realistic and accessible way. Now let's continue our project and add data to improve the replay behavior.
You can think of it this way: we have a file with all trading ticks executed on a certain day. However, using only the contents of this file, we will not be able to get really useful information from any indicator. Even if we use, for example, a 3-period moving average, which is exactly what is used in the JOE DI NAPOLI system, the signal will not be generated until at least 3 bars are created. Only after that, the moving average will be displayed on the chart. From the point of view of practical application, until today, this system is completely useless and inoperable.
Let's imagine a situation in which we want to conduct research in a 5-minute time frame. We will need to wait 15 minutes for the 3-period moving average to appear on the chart. It will take a few more minutes before any useful signals appear. That is, the system needs to be updated, and the purpose of this article is to discuss how to do this update.
You can see the system in action in the video below. It demonstrates how different indicators can be added to a replay system.
