need help: how to get PRICE_HIGH

[yoshi1988]

Hello

I am trying to get Price_High everytick. I want to output Price High to Control Log.

My OnTick() function outputs string, "Hello" everytick.

How do i output Price High everytick?

 Actually my final purpose is to get histgram of price difference, PRICE_OPEN - PRICE_CLOSE, monday to friday. Therefore, outputted data will be pasted into excel and utilized for histgram calculation.

//+------------------------------------------------------------------+
void OnTick()
  {
      //printf("Price_Close: " + (string)PRICE_CLOSE);
  // MqlRates bar_info[];
   printf("hello");
  // printf("bar price: " + (string)bar_info[0].open);
   
  }

You may have a look at the online doc and example code of "CopyRates".

BTW, if you only need the HLOC data, a script program is more suitable for that purpose than an EA.  The example code of "CopyRates" is just a script and you may customize it.

Hello

Thanks you very much for comment.

However, I have a problem that output of sample code is not what i expect.

I have tried sample code of CopyHigh as  angevoyageur  has implied.

I receive an identical values of Highest and Lowest while output is supposed to give distinct Highest and Lowest of tick.  

Why is that?

Below, code and output are posted.

 

Thank you
