Hi ceakuk,

Could you please explain to me what is the purpose if the following condition?

if (index == 0)

What are you trying to achieve?

Its the data at index=0 . But now I see  every tick upsdates the data so data for index ==0 changes.

How can I use a fixed   range of data for testing  indicator

RE: RE:

I'm trying to modify parameters to my indicator(not this)

my indicator creates custome renko chart with dynamic  pip size. however everytime i check on the renko it is  very different everytime because of changing data. if i change my parameters i can not know how they affect the renko chart because the data also changes. thanks

Hi ceakuk,

Currently there is no way to get a fixed range of market data. We plan to add this as an option of the MarkerSeries.GetData() function in a future release of cTrader. If you could share your indicator so that I can reproduce your problem then I might be able to suggest a different approach.

Hi ceakuk,

Yes, I believe this is possible. You could create another indicator that reads values from csv data and use it as an imput to your current indicator.

RE:

Thanks a lot even though I have no idea how to import data.

the only question I have is this

public override void Calculate(int index)
 {
 }

Usually  index belong to every tick in Market series I guess. if i import data, should i do a for loop every time i have index=0,1 2... or just once at  if(index==0)

or will the index now change to reflect the length of my  new csv data. Thanks

RE:

Dear Panagiotis,

Unfortunately what you propose  does not exist. These is no way to import data to  calgo indicator. I see no link to that anywhere. thanks

Hi ceakuk,

The fact that there is no link does not mean that this is not possible. Practically, you could read the data on the Initialize() function, store them in memory and then assign them to the appropriate Result index in the Calculate() function. However this requires some coding to be achieved. You could always use some professional help if you don't know how to do it and if you would like this to be implemented.

Best Regards,

Panagiotis

RE:

Thanks a lot. However I got a way around it. In case  someone else has the same problem, here is how I do it.

Sice for example hourly H2 data is longer than say H1 or Minutes30 etc

I switch to higher time frame like H2 and  do this

 if (index == 0)
                Print("tak=" + MarketSeries.OpenTime.Last(0) + "       " + MarketSeries.OpenTime.Last(0).Ticks);
            

now that I have  time "tik" in Ticks as the bigining I switch to my desired lower time eg H1.

I decide how long I want it say 50 days

long tak = MarketSeries.OpenTime.Last(0) that  i got earlier in above code;
long tik = tak + (number of days * 864000000000L);//1 day=864000000000L ticks
 if(MarketSeries.OpenTime.Last(0) >= tak && MarketSeries.OpenTime.Last(0<=tik )
{
    //ALL YOUR CALCULATE LOGIC GOES HERE
   //IF PRINT START & PRINT END ARE SHOWN IN LOG THEN YOUR DATA IS WITHIN THE BOUNDARIES
   if (MarketSeries.OpenTime.Last(0) == tak)
    {
          //begining              
         Print("start=" + MarketSeries.OpenTime.Last(0));
    }
    if (MarketSeries.OpenTime.Last(0).Ticks == tiktak)
    {               
    Print("end=" + MarketSeries.OpenTime.Last(0);
    }
}

RE: RE:

//CORRECTION
if (MarketSeries.OpenTime.Last(0).Ticks == tik)
{               
    Print("end=" + MarketSeries.OpenTime.Last(0);
 }
