Hi

if I have the two times

datetime starttime = iTime(Symbol(),PERIOD_D1,0)+ 3600*startHour + 60*startMinute;

datetime endtime = iTime(Symbol(),PERIOD_D1,0)+ 3600*endtHour + 60*endMinute;

How can I write the functions that gives me "true" back, when the actual time is between starttime and endtime

and give "false" back, if it is later or earlier?

Hi Again,

I got stuck in figuring this out. Could somebody enlighten me the correct way.

I have this indicator which i would like to use it multiple time on the same chart, thus giving it special prefix is probably the best way to differentiate from each other.

For example :-

string Prefix="Indi_1"; ObjectCreate(Prefix+"Box", OBJ_RECTANGLE, 0, time1, price1, time2, price2);

I can just change the prefix "Indi_1", "Indi_2", "Indi_3" and so on if i want to attach it to the same chart. However, it gets troublesome when it goes over 10 instances and beyond.

My question is, is there any workaround to use the same indicator without changing it's prefix manually ? Like giving it auto id to the indicator ?

You could do it from a loop (like for (int i=0; i < nnn; i++) ObjectCreate("Prefix_"+i+"Box", OBJ_RECTANGLE, 0, .....); ) but then you have to have times and prices stored in some array which would be accessible with the price1, price2 and so on ...

You have to decide which way would be easier to implement in your code

It is not so simple question as it seems to be.

I preferably use a dynamic prefix, that derives from rand() function. But sometimes indicators still get identical number from the rand(); my guess is the default seed for the rand() is taken from a clock counter, which lasts for 16 milliseconds.

So I use the GetTickCount (directly or as the seed for rand()), but I keep reading it in a loop until the value changes. Then I am sure no other indicator gets the same value, for a cost of decent delay.

Another way is to increment a stored prefix - place it somewhere (to global variables, or a file). The indicators work in sequence, so they do not interfere when saving the new prefix. This works until you delete the GV or file by accident.

Thanks Ovo, i will try to research more on this

Hi, i'm still having the same problem for this indicator. At the moment i was only able to figure out how to make incremental counter for indicator/object's id and i can attach it multiple time on the same chart.

But problem arise if i restart the terminal, it will act as i'm attaching another indicator which i'm not.

How do i filter this out ? Any help is appreciated. Thanks

If you want to use it in templates or you want to use multiple instances, the best way is that you enter the unique part of the name using parameters (that way even in templates, you can use those). Throw out the automatic counter and use FiboPrefixfor adding unique prefix and it will work perfectly in all the situations

Yeah thats my thought after several week of finding the suitable way. Hurmm..

Anyway thanks for replying Mladen. Would buy you a coffee if you live nearby. Lol
