Automation error System call failed?

[avishai]

I need to get the current price for about 400 stocks.

I only need the price to be updated every 30 seconds or so.


Every 30 seconds I am calling
for i:=0 to flstTickers.count-1 do begin
feSignal.RequestSymbol(symbol,0);
application.processmessages();
end;

later I call XMLgetbasicQuote from within the OnQuoteChanged event

I have tried this with the "applicaiton.processmessages" and without it, and I always get the same problem.

my problem is that during high volumes (like market open), the application crash, giving me a "Automation error System call failed" message.

My account has 500 symbols limit.

any ideas? this is causing us terrible problems and we really need a way to solve this.

Hi Avishai,

The Desktop API can efficiently handle about 50-100 symbols at a time. You may want to make your requests in smaller batches, process the data returned, then make your next request.

Thanks,
