What is the proper application of Classes in MQL4?

[Hoi Cheng]

I've been coding for about a year now but I've coded from a procedural paradigm.  If this then that, if price does this, modifyOrder that, so to speak

I noticed that MQL4 also can be an object orientated language but I just cannot conceieve where would object orientation apply to algorithmic trading.

Perhaps some here can shift my paradigm around object-orientation and MQL4.

Thank you kindly.

Encapsulate your iCustom calls to make your code self-documenting would be one example.
