Pls help on 4Hr TF code .

i am writing an sunday breakout EA, and it run on 4hr TF.
1 ) how to know, how many trade had open for that week?

2 ) in 4hr TF , how we going to read back the first 3 candle of the weeks? how we going to count the candle back to the first 3 ?

some people program the EA the way that it calculate all the information in certain hours or after an important candle, but there is an draw down that if the EA can only been turn on after that hours, then the EA might not work.
i looking for a way that event if the EA turn on at friday, it will auto get the first 3 candle value and check how many trade had open in that weeks.

any idea?

This code was extracted and simplified, but it should do what you want, but it may not be exactly right - it will get you started. You can figure out the startTime by figuring out the number of days and hours ago. So 6 days, 20 hours ago = Time[0] - 20*60*60 + 6*24*60*60.

3 bars from the current bar is = High[3], Low[3].

CodeMeister, thanks for your fast reply and your suggestion.

yes, you are right about using datetime to check the order of that week,
so there no way can do it by using date / day(the hard way).

about the second question , i think you misunderstand it.
what i means is example, if currently now 2010.03.10 8:00 candle in 4hr TF.
how can we get the 3 candlestick high low from 2010.03.07 20:00 to 2010.03.08 4:00 candlestick?

Now I understand. I think this will work.

High[ArrayMaximum(High, 3, 1)]/Point
Low[ArrayMinimum(Low, 3, 1)]/Point

Thanks ,CodeMeister
