iCustom VS file includes (MQH.) vs. libraries (. MQ4)

 
Hello,

iCustom VS file includes (MQH.) vs. libraries (. MQ4)
If I use the code in both, an indicator and a EA, what is the right place to put my code ?
Between iCustom, the include files (. MQH) or libraries (. MQ4), where to write my code?
And why ?

Thank you,
 
Imo, that depends on how much you know about them. Example their limitations, implementations etc. Where you choose to put them is a matter of preference. Your options for location is limited to Default_Folders or Expert_Folders. In theory, the more organized you are as a programmer, the easier your work will be in the future. How you choose to organize it totally up to you.
