Tutorial 36 – Pass data from radarscreen to chart with the Global Variables DLL

The Global Variable DLL provides a straightforward way of transferring data from one chart to another, from several charts to one chart, from Radarscreen to a chart, from OptionStation to a chart etc. In many ways its use has been superceded by the ELC DLL or by ELCollections and ADE, all available at the TradeStation support site, because it works fine in real time, but cannot be used where backtesting is required (at least not without a lot of complex effort) because global variable values stored by GlobalVariable.dll do not have date or time stamps.

The big advantage of the Gobal Variable DLL is that it is relatively simple to setup and easy to start using. If you download it from the Tradestation site, you get GlobalVariable.DLL, installation documentation, an ELD containing related functions and two workspaces containing a variety of implementations of the Global Variable DLL together with the programs that ‘send’ data and those that ‘receive’ data.

This tutorial demonstrates how easy it is for price data and be passed from Radarscreen to a chart.
