This is a
simple test I am trying to perform on the way to a more complex
looping system.
I discovered that
the following small piece of code produces a weird result in the AA
Window.
The calculated
values of RSI inside the loop produce "offset results" when sent to the AA
window via the AddColumn function.
AB =
CreateObject("Broker.Application");
AA =
AB.Analysis;
WL =
AA.Filter(0,
"WatchList");
WLSyms =
CategoryGetSymbols(categoryWatchlist,
WL);
if
(Name() ==
StrExtract(WLSyms,
0))
{
WLQty =
0;
for (i =
0; (Symbol =
StrExtract(WLSyms, i))
!= "";
i++)
{
WLQty = WLQty + 1;
SetForeign(Symbol);
RSIx = (RSI(14));
ROCx = (ROC(C,
14));
RestorePriceArrays();
}
}
RSIn =
RSI(
14
);
ROCn =
ROC(C,14);
Filter =
1;
Buy =
0;
AddTextColumn(Name(),"Name",1.0);
AddColumn(RSIx,"RSIx",1.2);
AddColumn(ROCx,"ROCx",1.2);
AddColumn(RSIn,"RSIn",1.2);
AddColumn(ROCn,"ROCn",1.2);
Notice the 0.00 for
RSIx for DJ-30 is the values for RUT-I--the thing is offset and I can not figure
out why or what is causing this to be offset.
The i in the
StrExtract command is supposed to be zero based, but the RSIx array is getting
switched (really offset) somehow.
There are only two
symbols in the Watchlist. The first symbol in the Watchlist is RUT-I,
while the second is DJ-30, so the order printed is reversed
also.

While you may not be that interested, I am attempting to modify some
code that FredT gave me here where I wanted to get the ordinal rank numbers for
symbols based on an indicator's value. Fred's code produced this just fine
for the last date in the From-To Range. I would like to modify the code
approach to calculate Rank Ordinals for each Bar, and this modification was a
step towards trying to accomplish that. But seeing the unexpected result
has me stopped.
Anyone care to speculate on what is going
on?
Thanks,
Ken
