Thanks, Maji. It helped. Correct me if I am wrong:

1. IndicatorCounted is useful in charts whose bars are updated in real time. So, instead of re-calculating the indicator values for all the bars when a new bar appears, only the indicator value for this new bar is calculated.

2. "limit" is simply the number of new bars, for which the indicator has to be calculated.

3. The indicator index [i] counts bars backwards, with i=0 indicating the new (current) bar.

I guess my confusion was based on my prior experience with Wealth-Lab, where an indicator code is written such that the indicator values are calculated for all the bars even if only the new bars need to be calculated. However, Wealth-Lab has some built-in smartness and it is possible that the indicators are automatically re-calculated for the new bars only. I am getting a feeling that MQL4 does not want make such decisions for you and leave these decisions to you by forcing you to make extra programming steps. I actually like that because I always hate when a software makes decisions for you and these decisions are not the same as yours. My only problem with MQL4 is that I wish it had better documentation.

fiqe,

I believe your assumptions are right. i think MT4 is right in just calculating the indicators once and WL hogs resources doing it the other way.

I maybe wrong, and I hope others more knowledgeable can correct both of us.

I am having some trouble figuring out the best way to solve calculating pivots based on GMT. Can anyone tell me how to have an EA calculate the OHLC of the previous day, however the day’s OHLC is based on 0GMT – 23GMT and the broker time is using GMT+3. I know it would be Highest(),Lowest(),iClose(), but how do you return the “shift” of the bar that starts at 0GMT of the previous day?

Nick,

Check your email. I have sent you an example there.

Let me know.

Maji

OK , I think U can do this like that:
First u have to point what hour are u searching - if your broker is GMT+3 then to count Pivots on GMT time u have to decerase brokers time by 3. So If u search for hour 00.00 u will search for 21.00 at your broker time.

Now, one day is 24 hours and we start to search from right part of the screen. Your broker time is +3 so we will be adding that numbet to shift value.

Code:

for(int i = 3 ; i <= 27 ; i++)
{

     if(TimeHour(Time[i])==21)
     {
       //This should be your GMT midnight so u can take OHLC values from here
       double open = iOpen(Symbol(),60,i);
       double high = iHigh(Symbol(),60,i);
       double low = iLow(Symbol(),60,i);
       double close = iClose(Symbol(),60,i);
     }
     
}

I don't know if this is a simple way, but it works.

Hi,
In the last version of SimpleDailyRangeBreakoutExpert you can find code for making of candle(OHLC) for any time zone.

Sorry, I forgot to specify that i am looking for the daily OHLC based on GMT where broker os not. I will check out the code... THANKS!

You can read the MQL programming guide , it's a very basic question and you will have more problem in future if you don't pay time to read the mql guide,
