Welcome to tutorial 25 in this series of tutorials to help you learn TradeStation EasyLanguage programming skills. The idea behind the series is that if you can program with TradeStation EasyLanguage yourself, you will have a skill that will enable you to try out trading ideas without the need to use a professional programmer.
The purpose of this video tutorial is to demonstrate the programming techniques rather than to create a tradable indicator. This tutorial was created using TradeStation version 8.6 but works with version 9.5 and 10.
This video tutorial aims to explain the way the ‘smoothed’ indicators work and how Radarscreen requires additional bars to be loaded to ensure that the values shown in Radarscreen are the same as those shown on a chart. In this tutorial I demonstrate how TradeStation sets MaxBarsBack using auto-detect. I also create a new function that starts calculating an exponential average at a specific bar. This is useful in demonstrating how the exponential values converge and why it is necessary to use the ‘load additional bars’ setting in Radarscreen.
