No. But if you plan on updating the data for recent trades, Quote Editor
will not let you add a -1. You either add the recent quotes to your .csv
file and re-import -or- you allow a 2 to represent a short and "fix" it
with this code or similar:
sig1 = ParamStr("Enter ticker of 1st Signal");
//...
tradeSig1 = ParamToggle("Trade Signal 1","Off,On",1);
//...
SetForeign(Sig1);
cond1 = C;
sig1FN = FullName(); //Store the FullName
cond1 = IIf(cond1 == 1,1,IIf(cond1 == 0 OR cond1 == 3,0,-1));
cond1 = cond1 * tradeSig1; //Allows to turn off Sig1
if (sig1 == "None") tradeSig1 = False; //if True no ticker picked
RestorePriceArrays();
The above example sets:
1 = 1 (or long)
0 and 3 = 0 (or Cash)
any other value = -1 (or Short)

So, Terry, are you saying I need to replace the -1's with 2's before
importing? Then convert the 2's to -1's when I plot with 'foreign'?
Not sure I understand, but maybe it will be apparent after I give
this a try.
