• Unzip and place in experts/scripts folder. (Hampster FREE Zip Archiver - HERE - as of Jan-2014 no crapware in download).
  
• Note
  
• 
• Test: Drag a SL Script onto the chart.
• Test: Dragging another SL Script onto the chart will cause the SL to adjust to the new value. Same applies for TP.
• Point and pip calculators can be added
  

Follow these steps

1. The downloaded Scripts should be in the experts/scripts folder.
2. Choose a SL Script and test that it works with your MT4. Prove that it works - you do not want to waste your time with something that does not work.
   
3. Press Ctrl+N which will open the Navigator Pane.
   
4. If any other pane is also open, to avoid clutter, it can be closed. Click x at top-right of the relevant pane.
5. Locate the tested SL Script under the Script folder.
   
6. Right click on SL Script and select Modify - Enter. Image 1 shows 0-A-SL-0500 selected in the Scripts folder.

8. 
   
9. Left click or press the Enter Key to open the source code in the MetaEditor.
10. The source code will open in the MetaEditor – see Image 2. Note the SL Script name on the code window tab and right of the yellow diamond icon at top.
    
11. If more than one code window is loaded in the MetaEditor close each window (right click in the area of the name tab of the code window → click close) and leave only the tested SL Script code open. For beginners less mistakes are made this way.
    
12. The only code you will need to change are the numerical values highlighted in red and blue.
    
13. Stop ! Before changing any code the next action is to save the Script to another name. This ensures that the original script code is not replaced with unintended edits.

Continue....

1. If more than one code window is loaded in the MetaEditor ensure that the correct code widow is selected.
   
2. Click on File → Save As.
3. Change the name from O-A SL 500.mq4 to 0-A SL 0800.mq4 or whatever SL value you have chosen. (0020, 0050, 0100, 0200, 1000 etc., naming is applied because it ensures consecutive numbering; if not 100 will appear before 1 to 99. As the maximum SL number is in thousands 4 digits are used to ensure consecutive numerical naming increment in the Navigator Pane. A and B are used to separate SL and TP groups respectively. 0 preceding A and B ensures that the entire collection is kept separate from other scripts.)
   
4. Click the Save button.
5. MedaEditor – [0-A SL-A SL 0800.mq4] will now be indicated right of the yellow icon and 0-A SL 0800.mq4 on the code window tab. Although 0-A-SL-0500.mq4 is no longer visible in the MetaEditor it remains - unchanged - in the experts/scripts folder.
   

The only code to edit are the two 500 numbers.

// Script: 0-A SL 500

extern int StopLoss = 500;

Relevant Information

The code behind the Inputs Tab of Scripts, Indicators and Expert Advisors can always be located by finding the code word 'extern' (without quotations) which will always be near the top of the program.

The code word 'int' stands for integer (..-2, -1, 0, 1, 2, ..). Basically negative or positive numbers that do not include decimals places. 'Int' defines 'Stoploss' as an integer value.

The code to change - as far basic edits go - will be the code after the = sign. Eg1: extern color Line_Color = Red; - Change Red to Blue or Green etc. Eg2: extern int Line_Width = 1; - Change 1 to 2, 3, 4 or 5. Eg3: extern string Font_Type = "Arial"; - Change Arial to "Arial Bold" or "Verdana". Note quotation marks (" bla") required for parameters of string variables (extern string ...... = "bla";).

Text after // is used as descriptive comment and excluded from code function. Sometimes code is commented out (// ..bla bla.. or /*..bla bla...*/ ) for reasons like fault finding by process of elimination.

Editing

1. Change the two 500 numbers to your chosen numerical value and remember to include the semicolon (;) where applicable. The numerical value should form part of the script name (i.e. 0-A-SL-0800.mq4) for fast identification..

2. // Script: 0-A SL 800 
   

3. extern int StopLoss = 800;

4. Click the Compile button. Always remember to compile. Edited code will not become effective until it is compiled.
   
5. Check the left hand bottom of the MetaEditor for 0 errors and 0 warnings in the ToolBox (Ctrl+T).
6. Image 3
   
7. 
8. If an error is flagged the code will not compile and the code must compile for the program to work.
9. If an error is flagged press Ctrl+Z in steps and follow the code in the MetaEditors as it is undone and returned to original copy. Try to determine where a mistake was made for future reference and learning.
10. Click the Compile button to test that the code is free of errors and start again.
11. If, after the edit of 500 to 800 no errors have been flagged in the Toolbox the New 0-A-SL-0800 Script will be found in the Scripts folder ready for use..

Testing

1. Open a trade in the MT4 demo.
2. Attach Script 0-A-SL-0500 to the the chart. A red SL Line at 500 points from entry will be drawn across the chart.
3. Check SL difference against Entry price to ascertain accuracy.
   
4. Attach Script 0-A-SL-0800 to the chart. The red SL Line will jump from 500 to 800 points from entry.
5. Check SL difference against Entry price to ascertain accuracy.
6. To delete the Stoploss attach Script 0-A-SL-Delete to the chart.

Apply the same procedure to other Scripts.

double: def - real number - includes fraction part.

int: def - (integer) whole number - no fraction part.
