Re: [amibroker] Question re: Automatic Refresh of Static Variables from Code

["Tomasz Janeczko" <amibroker@xxxxxx>]

Tim,

RefreshAll triggers refresh not more often than once per second.
Apparently your stock tree is very large and takes more than one second to refresh.
Right now a solution is to:
a) CLOSE stock tree so RefreshAll does not need to refresh it.

b)

Use this:

 periods = Param("periods", 10,1,25,1);

if( StaticVarGet("periods") != periods )
{
 StaticVarSet("periods",periods);
 oAB = CreateObject("Broker.Application");
 oAB.RefreshAll();
}

Plot(RSI(periods), "RSI", colorRed);

Best regards,
Tomasz Janeczko
