Tutorial 57 – Using logical operators

Welcome to tutorial 57 in this series of tutorials designed to help you learn TradeStation EasyLanguage.THIS IS A BEGINNER LEVEL TUTORIAL.

Someone on the mailing list noticed that in the Program 14 video, TradeStation gave some warning messages. If you had looked a little closer you would have seen the message said: “Warning: The expression uses logical operators AND and OR.  Use of parenthesis will ensure the expression is evaluated in a manner consistent with your intent.  Please consult the online help for information regarding a change made in 8.8 that affects evaluation of logical expressions.”

This tutorial provides a simple and trivial example of how parentheses could be used to clarify the meaning of a logical expression.
