Hi,
In Amibroker version 6.10, I've been trying to update the properties of a group of symbols in a watchlist without success. Here's what I've tried so far:
1) In the AA window, Apply to -> Filter -> MyWatchlist, Range -> 1 recent bar(s), Scan
AFL:
AB = CreateObject( "Broker.Application" );
st = AB.Stocks( Name() );
st.MarginDeposit = 5200;
Result: Error 18. COM object variable is not initiated or has invalid type (valid COM object handle required)
If i remove the last line, the scan does not throw an error.
2) Same AA window set-up as #1
AFL:
AB = CreateObject( "Broker.Application" );
sts = AB.Stocks();
qty = sts.Count;
for( i=qty-1; i>=0; i=i-1 )
{
st = sts.item(i);
st.MarginDeposit = 5200;
}
Result: all symbols in all watchlists have been changed...in other words, the code ignored the filter setting in the AA window.
How do I isolate the symbols in the watchlist when running a scan to change only their properties?
Many thanks
