Just some infor about what is open and close bar concerning signal systems (and according to coders' understanding when you will want to descrie the coders your rules to be coded).
If you will say:
sell on bar #1, or sell on close bar (in most cases it is previous close bar), or sell on previous bar (in most cases it is previous close bar) so very coder will understand you that you are talking about close price forjust one previous bar.
Otherwise the coders will ask for the ules, or will ignore the request.
