AlgoWizard (SQX Pro 135.868) - Constants are defined as External Variables in MT4 source code

Constants are defined as External Variables and appear in the Inputs Tab of the MT4 Terminal. As new variables are added during testing and new iterations of the mq4 file are compiled and tested, MT4 can overwrite and change the constant's value as they shift around in the Input tab page, causing simple calculations to fail with incorrect results. The constants also shift around and are renamed by AlgoWizard as the strategy is modified and recompiled.

I reported this problem over a year ago and was told that this is how MT4 behaves. True, but it is still a HUGE PROBLEM.


The root issue is that CONSTANTS should not be allowed to be changed, ever!  Constants are constant and should not appear in the MT4 Inputs Tab.


To clarify, the constants I'm referring to are real constants like the "2" used in the following expression:  (Ask - Bid) / 2
The '2' should never be allowed to be altered in value. '2' must always be '2'. It is not intended to be a variable, and should not be compiled as a variable.
