Tutorial 51 – Using data from multiple data streams in a strategy

Welcome to tutorial 51 in this series of tutorials designed to help you learn TradeStation EasyLanguage. This tutorial was created using TradeStation 8.7.

In this tutorial I create a simple strategy that uses data from two data streams (data1 – 5 minute e-mini and data2 – 60 minute e-mini).Stochastic indicators applied to data1 and data2

The image to the right shows the chart with standard TradeStation stochastic indicators applied to it.

When creating a strategy such as this, the important thing is take make sure that references to a data stream higher than data 1 are properly aliased. I show this in the video.

In addition, the demonstration program is included below. Bear in mind that I have included this in order to demonstrate the programming technique, not because I am suggesting, in any way, that it is a viable trading strategy.

Inputs: StochLength( 14 ), // User defined inputs to control Stochastics calls
StochLength1( 3 ), // User defined inputs to control Stochastics calls
StochLength2( 3 ); // User defined inputs to control Stochastics calls

Variables: oData1FastK( 0 ), // Values returned by the Stochastic function
oData1FastD( 0 ), // Values returned by the Stochastic function
oData1SlowK( 0 ), // Values returned by the Stochastic function
oData1SlowD( 0 ), // Values returned by the Stochastic function
oData2FastK( 0, Data2 ), // Values returned by the Stochastic function – N.B. aliasing for the Data2 data stream
oData2FastD( 0, Data2 ), // Values returned by the Stochastic function – N.B. aliasing for the Data2 data stream
oData2SlowK( 0, Data2 ), // Values returned by the Stochastic function – N.B. aliasing for the Data2 data stream
oData2SlowD( 0, Data2 ); // Values returned by the Stochastic function – N.B. aliasing for the Data2 data stream

// **********************************************************************************************

// Call the Stochastic to calculate the oData1FastK through oData1SlowD values for the first data stream (5 minutes)
Value1 = Stochastic( H, L, C, StochLength, StochLength1, StochLength2, 1, oData1FastK, oData1FastD, oData1SlowK, oData1SlowD ) ;

// Call the Stochastic to calculate the oData2FastK through oData2SlowD values for the second data stream (60 minutes)
// Note aliasing of the price variables, High, Low, Close to Data2, and of the entire function to Data2 (at the end of the call)
Value1 = Stochastic( H of Data2, L of Data2, C of Data2, StochLength, StochLength1, StochLength2, 1, oData2FastK, oData2FastD, oData2SlowK, oData2SlowD ) of Data2 ;

// **********************************************************************************************

If oData1SlowK Crosses Above oData1SlowD and oData2SlowK > oData2SlowD
then Buy Next Bar at Market;

If oData1SlowK Crosses Below oData1SlowD and oData2SlowK < oData2SlowD
then Sell Short Next Bar at Market;

EasyLanguage is a programming language that is part of the TradeStation trading platform. It can be used to write programs to help in the technical analysis and trading of foreign exchange (forex or FX), commodities (e.g. the Dow e-mini, S&P e-mini etc), options, and stocks.
