[amibroker] Re: ValueWhen(Ref()) question

OK, I've tried my best, but I now presume that it cannot be done in Amibroker i.e 
correctly reference the last trade in a backtest ( without resorting to some sort of 
workaround). I've searched the archives, and despite trying to use relevant search 
criteria I cannot find a solution.

Just to clarify, in case I've not made myself clear, I wish to SAR a trade if the original 
entry criteria is voided. eg a close under the low of a Buy entry bar.  To do this ( under 
a backtest) I need to be able to reference the H,L,C,O for that particular signal.
As previously posted, using something like "Sell = C < LastValue(ValueWhen(Buy, Low));" 
only references the very last signal in a backtest, instead of stepping through each 
signal as it is generated.
Anyone???
