I have had a lot of people interested in TradersStudio recently who have never programmed and this was their main concern in buying the product. I thought I would start this thread to help people get a handle on basic programming concepts. TradersStudio and TradeStation both use the concept that code is written to execute on one bar at a time. Past values are stored in variables, where you can access what value that variable had on different past bars. The structure of both EasyLanguage and TradersStudio Basic are similar which is why we can translate EasyLanguage. I am sure this thread will be a value to both groups of users.
