a221 – code editor – S-Trader Desktop

The Quant Script^TM language is not only powerful and versatile but also easy to use. There is a minimal learning curve to climb for beginning to use the Quant Script^TM Code Editor; and there is a ZERO learning curve for beginning to use the Quant Script^TM Code Wizard. Scripts built with either tool will achieve the exact same result and will behave the exact same way so using one or the other is strictly a matter of personal preference.

Very importantly, whether you use the Code Editor or the Code Wizard, for scripts to be usable and compatible with all S-Trader modules, they must return a result function as well as its inverse, i.e. a reverse result function. The script structure should therefore be:

All script code and programming logic;

SET RESULT = code and portion of the script for the function the script is supposed to return;

SET REVERSE_RESULT = code and portion of the script for the inverse of the function the script is supposed to return.

Let us look at an example of a simple script measuring the average percentage deviation of three moving averages for 10, 20 and 30 periods, respectively, from closing prices:

Step 1

Defining the 10, 20 and 30 Exponential Moving Averages of Closing Prices
- SET EMA10 = ExponentialMovingAverage(CLOSE,10)
- SET EMA20 = ExponentialMovingAverage(CLOSE,20)
- SET EMA30 = ExponentialMovingAverage(CLOSE,30)

Step 2

Defining the SUM deviation of the three Exponential Moving Averages from Closing Prices
- SET EMASUM = EMA10 + EMA20 + EMA30 – (3)*(CLOSE)

Step 3

Defining the RESULT function, i.e. the average percentage deviation of the three Exponential Moving Averages from Closing Prices
- SET RESULT = (EMASUM) / ( (3)*(CLOSE) )

Step 4

Defining the REVERSE_RESULT inverse function
- SET REVERSE_RESULT = (-1) * (RESULT)
