When trading with Tradestation7,is it possible to chart the spread of a pairs trade as a bar chart in any time frame you wish or do you just have to chart 2 charts of each share.I phoned Tradestation but I might as well have been talking double dutch
You can plot any mathematical relationship, then make the two charts Hidden and just view the spread - or use a different y axis for the spread variable.
You can do as dloomis suggests above, but I don't think you can get a bar or candle chart out of the spread, just a line. It computes the value on the close of the 'bar'.
