Hi folks,
I can't seem to get this to work. Here is my code:
// Exploration code to clear a watchlist
function ClearWatchList(_watchListNumber)
{_toClear = CategoryGetSymbols(categoryWatchlist, _watchListNumber);
for(i = 0; (symC = StrExtract(_toClear, i) ) != ""; i++)
{CategoryRemoveSymbol(symC, categoryWatchlist, _watchListNumber);}
}
ClearWatchList(4);
Filter=True;
I read in the help files that the "GetCatagorySymbols" was changed to
"CatagoryGetSymbols" and so I am using that Function.
It is probably something simple.
I am trying to run the code above as a simple exploration to clear out
a single watchlist. The loop code below will be next. Then I am
thinking of using the #include function to add it to a number of my
explorations. My thinking is that this small piece of code will be
easier to manage from one file than if I copy and paste into all of my
explorations.
