Error 060 Out of memory

Hi all,

I have 10 years of minute data for 600 tickers. I was trying to look for gaps in quotes with a script below. But as expected I get the "Error 060: Out of memory". I wonder if it is possible to clean memory in the script, e.g. after 10 symbols are done? I was of course reducing # of assets and/or reducing period (e.g. 100 symbols for 2 years works), but I would like to avoid this manual work. Thank you.

Code

function run()
{
    StartDate = 20100101;
    EndDate = 20201231;

	BarPeriod = 1;	
	LookBack = 0;

	string filename = "Stocks_gaps.csv"; 

	if(is(INITRUN)) // specifying the header in the first run
	{
		char header[500];
		sprintf(header, "Asset, UTCDate, DoW, Time, Gap_Minutes, \n");
		file_delete(filename);
		file_append(filename, header);
	}

    assetList("AssetsMyStonks100.csv");
    History = "*_us_stock.t6"; 	
    Detrend = NOPRICE; // prevents that asset and price data is checked and outliers are removed
    while(asset(loop(Assets)))
            {	
            var tdiff = (wdate() - wdate(1));	// time difference in days of the last consecutive bars
            if(tdiff > (BarPeriod/1440)*2 && dow() == dow(1)) 
                    {	
                        char line[500];
                        sprintf(line, "%s, %d-%02d-%02d, %i, %02d:%02d, %i, \n", 
                                    Asset, year(), month(), day(), dow(), hour(), minute(),minutesAgo(1));
                        file_append(filename, line);
                    }
            }	
}
