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. Any thoughts what went wrong? Appreciate any helps based on your experiences. Thanks in advance ...
