Up Down Price Counter

New comment
 

Hi guys, 

    Actually I'm not expert in mql4 language but  really need to create an indicator or EA that can count how many times the price go up and how many times go down above and under a given levels (level1 and level0). 

figure illustrates how should the code works

In this example the price go up 1 time above Level1 and 3 times below Level0.

any help will be apreciated.


Regards.

 

You may use a ZigZag as a source of extremum points. Then the algorithm can be something like that (in pseudo-code, off the top of my head):

cycle through all ZigZag extremums (by i, 0 - is most recent)
{
  cycle through all levels of interest (by j)
  {
    if extremum[i] > level[j] and extremum[i + 1] < level[j]
    {
      countUp[j]++
    }
    if extremum[i] < level[j] and extremum[i + 1] > level[j]
    {
      countDown[j]++
    }
  }
}

According to your code I think when the condition "if" is true the counter countUp or countDown will iterate (add 1) every new tick  as long as condition "if" is true, while we want to add only 1 iteration regardless of any new tick.

This is up to you to decide when to call this stuff - on every tick or bar - from the mentioning ZigZag you should easily deduce that it's apparently for bar by bar execution, and even more - it requires to check that latest ZigZag extremum became stable. This is just a sketch which you need to improve in many aspects, including caching cumulative results for already calculated bars.

Thanks it's work.
