Bug in MT4 Compiler?

Hi guys

It is only me or also you are having problem with this:

I am writing code in mq4 and test in Skill Tester. I do some change (for example change in code from 21 MA to 50 MA and change TimeFrame from 5 to 15 etc) then I hit Compile and run Skill Tester. If code is fresh and in new mq4 file everything is ok but after several testings with another inputs (different MAs and TFs) MT4 is not "saving" new changes after I hit Compile. For example I have tested something in 15M chart and switch to 60M therefore I have also rewrite TF in my code and hit Compile. Then I have run SkillTester with new settings but get old results. Then I have found that Compile didn't change settings that I have made. I have hit Compile several times but still it didn't change that new properties. But when I copy whole code and put it to fresh new EA file then it is working. This happened after 10 maybe more changes in old code. After that Compiler is starting ignoring new changes in code. Can anybody tell me what exactly is happening?

THX

If you are using extern variables, after re-compiling with new extern values, open Expert Properties in the strategy tester and click reset.

OK and when I will delete extern and use without that then I will not have this problem? It is only because of that extern "setup"?

I don't know because I don't know what changes you have made to your code.
But if you make changes to the default extern variables in your code, make sure that you click on reset, to use the new extern values.

I have change all my extern variables to "intern" and looks that it is working. Thanks for great tip.
Gurmai I have another Q.

How you will do this?
Average value of Volume from last 12 candles???
I can pick highest or lowest but how to average some candles period?

Something like this should work, I don't know whether this is the best way or not.
Inserted Code
  static datetime NewBar;
  if(NewBar!=Time[])
    {
    NewBar=Time[];
    double sum = 0;
    
    for( int index = 12; index >0; index-- )
       sum += Volume[index];
    double av_volume = sum/12;
    }
