However, C (-1) and H-L (-1) keeps on changing rather than refering to yesterday's Close and yesterday H-L. It seems Amibroker pick up latest bar C and H-L rather than yesterday's C and H-L.
Any thoughts what went wrong? Appreciate any helps based on your experiences. Thanks in advance ... plz understand the function Ref(array,period) properly- Ref(C,-1) shall show close of previous day only when timeframe is daily,if it is 1 min,then it shall give the close of previous bar. --- On Tue, 4/6/10, Teguh P <[email protected]> wrote: From: Teguh P <[email protected]> Subject: [amibroker] Refering to Yesterday Close (with ESignal) To: [email protected] Date: Tuesday, April 6, 2010, 11:24 PM I have quick question on refering to yesterday's C (and H-L) for Explore function. For background, I am using ESignal data feed. I run below my AFL at 9.30 EST right at the market open to get opening price and gap vs yesterday close. AddColumn(Ref( C,-1), "Close" ); AddColumn(Ref( H-L,-1), "Range"); AddColumn( O, "Open"); Anytime I run the exploration (i.e. 9.30am, 9.40am), Open always refers to today's Open which is what I expect. However, C (-1) and H-L (-1) keeps on changing rather than refering to yesterday's Close and yesterday H-L. It seems Amibroker pick up latest bar C and H-L rather than yesterday's C and H-L.
