Not for stocks, but for ETFs. But we'll try to find an alternative solution.

Here's a modified Google download script that does not crash anymore when an asset is not found:
Code:
void main()
{
	int N = assetList("AssetsZ8");
	while(--N >= 0) 
	{
		string URL = strf("https://www.google.com/finance/historical?q=%s&startdate=01-Jan-2000&output=csv",Assets[N]);
		string Content = http_transfer(URL,0);
		if(!Content) continue;
		file_write("History\\history.csv",Content,0);
		dataNew(1,0,7);
		if(!dataParse(1,"%d-%b-%y,f3,f1,f2,f4,f6","History\\history.csv"))
			continue;
		printf(" %s",Assets[N]);
		dataSave(1,strf("History\\%s.t6",Assets[N]));
	}
}
