Strategy tester: load external parameters from file dependent on date

[Vvv Kkk]

Hi, I was trying to find but I dont see such a topics before

I have a parameter dependent on a date - in a real time its ok - I can just load it from file daily and use it 

What I was expecting from strategy tester: that I can upload the whole file

format is

date1,par1

date2,par2,

etc

OnInit():

<load file and put it to arrays: dates and pars>

and in OnTick() I write:

datetime cur_date = TimeCurrent(); // I assume that in tester it will be historical date

double cur_par;

for (int i = array_size-1; i >= 0; i--)

{

	if (cur_date > dates[i]) // in tester we found that - historical date of tester
	{
		cur_par = pars[i]; // historical value of parameter
		break;
	}

} 

So, when expert is running - its ok - so Init() works - file is loaded and in OnTick() it derives parameter which is actually the current one (today is the last date in file) - so I just tested this 

And I expected that strategy tester actually reproduces all the code including OnInit() and OnTick() but from logs I dont see any parameters loaded 

Could you please advise or direct me to right direction 

Am I inventing a wheel over here and there is another way or just it is not possible at all?

Many thanks

What is the function start() ?
