As I compile my include file, no errors appear. However, when I run my script, it alerts me "zero divide" in the include file. Unfortunately I could narrow down the source of the problem. I have no idea how to solve this error. I'd appreciate anyone who could assist me.

It's not that hard to find the dividers..... now use the debugger to check the values and adjust your code to control them.
double UpperWick; double UpperWickinPips = UpperWick / (GetPipValue());given that you assign no value to UpperWick you should start there
-
Those are not assignments; they are initialization of a common (globally declared), or static variable with a constant. They work exactly the same way in MT4/MT5/C/C++.
-
They are initialized once on program load.
-
They don't update unless you assign to them.
-
In C/C++ you can only initialize them with constants, and they default to zero. In MTx you should only initialize them with constants. There is no default in MT5, or MT4 with strict (which you should always use).
MT4/MT5 actually compiles with non-constants, but the order that they are initialized is unspecified and
Don't try to use any price or server related functions in OnInit (or on load or in OnTimer before you've received a tick), as there may be no connection/chart yet:
- Terminal starts.
- Indicators/EAs are loaded. Static and globally declared variables are initialized. (Do not depend on a specific order.)
- OnInit is called.
- For indicators OnCalculate is called with any existing history.
- Human may have to enter password, connection to server begins.
- New history is received, OnCalculate called again.
- New tick is received, OnCalculate/OnTick is called. Now TickValue, TimeCurrent, account information and prices are valid.
-
Unlike indicators, EAs are not reloaded on chart change so you must reinitialize them, if necessary.
