Advanced Edition is now Available

Advanced Topics Cover

The last book in the Easing Into EasyLanguage Series has finally been put to bed.  Unlike the first two books in the series, where the major focus and objective was to introduce basic programming ideas to help get  new EasyLanguages users up to speed, this edition introduces more Advanced topics and the code to develop and program them.

Buy this book to learn how to overcome the obstacles that may be holding you back from developing your ideal Analysis Technique. This book could be thousands of pages long because the number of topics could be infinite. The subjects covered in this edition provide a great cross-section of knowledge that can be used further down the road. The tutorials will cover subjects such as:

  • Arrays – single and multiple dimensions
  • Functions – creation and communicating via Passed by Value and Passed by Reference
  • Finite State Machine – implemented via the Switch-Case programming construct
  • String Manipulation – construction and deconstruction of strings using EasyLanguage functions
  • Hash Table and Hash Index – a data structure(s) that contains unique addresses of bins that can contain N records
  • Using Hash Tables – accessing and storing data related to unique Tokens
  • Token Generation – an individual instance of a type of symbol
  • Seasonality – in depth analysis of the Ruggiero/Barna and Sheldon Knight Universal Seasonal data
  • File Manipulation – creating, deleting and writing to external files
  • Using Projects – organizing Analysis Techniques by grouping support functions and code into a single entity
  • Text Graphic Objects – extracting text from a chart and storing the object information in arrays for later development into a strategy
  • Commitment of Traders Report – TradeStation only (not MultiChart compatible) code. Converting the COT indicator and using the FundValue functionality to develop a trading strategy
  • Multiple Time Frame based indicator – use five discrete time frames and pump the data into a single indicator – “traffic stop light” feel

Once you become a programmer, of any language, you must continually work on honing your craft.  This book shows you how to use your knowledge as building blocks to complete some really cool and advanced topics.

Data Aliasing with Minute Bars

Why It Is Important to Connect Variables with Correct Time Frame

I had a question about data aliasing from a reader of this blog.  Here is the debug code I used in the form of an Indicator.

//vars: myCloseData1(0),myCloseData2(0),
//      myRSIData1(0),myRSIData2(0);
      
vars: myCloseData1(0),myCloseData2(0,data2),
      myRSIData1(0),myRSIData2(0,data2);

 
myCloseData1 = close of data1;
myCloseData2 = close of data2;

myRSIData1 = rsi(close of data1,14);
myRSIData2 = rsi(close of data2,14);


Print(d," ",t," --------------- ");

print(" myCloseData1[0]: ",myCloseData1[0],"  myCloseData2[0]: ",myCloseData2[0]); 
print(" myCloseData1[1]: ",myCloseData1[1],"  myCloseData2[1]: ",myCloseData2[1]);
print(" myCloseData1[2]: ",myCloseData1[2],"  myCloseData2[2]: ",myCloseData2[2]);
print(" myCloseData1[3]: ",myCloseData1[3],"  myCloseData2[3]: ",myCloseData2[3]);

print(" myRSIData1[0]: ",myRSIData1[0]," myRSIData2[0]: ",myRSIData2[0]);
print(" myRSIData1[1]: ",myRSIData1[1]," myRSIData2[1]: ",myRSIData2[1]);
print(" myRSIData1[2]: ",myRSIData1[2]," myRSIData1[2]: ",myRSIData2[2]);
print(" myRSIData1[3]: ",myRSIData1[3]," myRSIData1[3]: ",myRSIData2[3]);
Illustrating Difference Between Data Aliasing and Not Data Aliasing

If you have a higher resolution as Data 1 (5 minute in this case) than Data 2 (15 minute), then you must use Data Aliasing if you are going to use a variable to represent a price or a function output.  With out Data Aliasing all data references are in terms of Data 1.  When the 15 minute bar closes then the current [0] and one bar back[ 1] will be correct – going back further in time will reflect correct data.  During the 15 minute bar only the last value [0] will show the correct reading of the last completed 15 minute bar.  Once you tie the variable to its correct time frame variableName(0, Data2), you can then reference historic bars in the same fashion as if it were Data1.  This includes price references and function output values.

Check this chart out and see if it makes sense to you.  I dedicate a portion of a Tutorial on Data Aliasing in my latest book due out next week – Easing Into EasyLanguage – Advanced Topics.
