Question about assigning variables in MQL4

New comment
 

Hi, 

I'm totally new to coding on MT4/MQL4 and had a question, maybe a dumb one. I have a Portfolio EA which contains 100 individual EA strategies. It works quite well but each time I want to tweak the SL or TP, I need to change 100 lines of code. Boring. Is it possible in MT4 to set a variable to a level or indicator and use the variable instead?

Example 1 : Instead of saying -

Take Profit = 25 (and repeating this 100 times in the code for each EA) 

I would have something like 

x = 25

Take Profit = x

- and therefore just change the initial assignment of x to change up the value. 


Example 2: Instead of saying - 

x = ATR of Current Daily Chart

Take Profit = x/2

I dont need anyone to write the code for me :) That would take the fun out of learning - I read some technical docs and see that all needs to declared first etc, but at this stage I would just like to know if it's technically possible. 

Thanks 

Matthew
