Hi, Please note this is off message board.
Did you get any suggestions? Below is what I do for 10 beta stocks to take the open of the trading day and run some averages on 10 stocks and then compare to the index. Perhaps you could use some part of it. Have not traded ETF's but would like to help on this to learn more. We might have to look at timeframe set or foreign, depends on what type of charts you are using, 1 minute, range, tick. Need a little more info? What is the diff between the ETF and future price? Same or always, x number points off or??? Anyway Regards, JG SetForeign( "AApl-ISLAND", True ); AAPLOpen = TimeFrameGetPrice( "O", inDaily, 1 ); AAPLClose = Foreign( "AApl-ISLAND", "close", 1 ); AAPLChange = AAPLClose - AAPLOpen; AAPLPerCentChange = ( AAPLChange / AAPLOpen ) ; RestorePriceArrays(); -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of analyticalgnome Sent: Saturday, August 07, 2010 2:23 PM To: [email protected] Subject: [amibroker] Daily ETF charts not accurate vs 24 hrs futures charts they are based on After using Amibroker for 1.5 yrs, and trading bull and bear crude oil ETFs for 1 yr, I've realized a huge problem. The crude oil futures the ETFs are based on trade 24 hrs a day and so these charts have accurate nice smooth indicator readings which you can make trading decisions on. But the EFTs however can have huge gap ups and downs in the morning. This results in the ETF longer term indicators not being useful for a time after opening. For example after certain long weekends it takes up to 4 days for the 15 min 192 moving average to become accurate. One idea around bad ETF charts is to have Amibroker convert 24 hr futures data into ETF prices. I've studies the AFL reference guide but can't figure out how to convert price data and then plot price bars for 2x bull and bear ETFs. Anyone know how? Or have any other ideas about the above dilemma? ------------------------------------ **** IMPORTANT PLEASE READ **** This group is for the discussion between users only.
