Debra, use the appropriate date value... ie close(0) is today close(-1) is yesterday an easy way to find the value is to run this scan and guess at the value for the date you want ... it will print 30 days either side of it...for your reference... place your best guess after md1:=.... click on cancel after you begin the scan... ( I have not figured an elegant way to stop this scan yet...I guess your input scan could just have one issue in it..) then a list of dates and their corresponding date value will be listed to use in your date specific scan... my math is bad so I take two meds and run this scan...>g< bdog //input="prescan.lst"; output="day.lst"; integer md1,m; //******enter value md1:=-150; //*********** for m= (md1-30) to (md1+30) step 1 do println m:8,date(m):12; next m; println; println;

Move everything back one day. For example, instead of close(0), make it close(-1). Instead of stochrsi(0)>30, you'd have stochrsi(-1)>30. If you want to get more adventuresome, sling a for loop in there. For a basic for loop, you need to: 1. Declare the variable: integer i; 2. Define the loop: for i = -2 to 0 step 1 do 3. Put i in the scan function: close(i) or stochrsi(i) 4. Add a "next i" after the print statement. Here's an example: output="test.lst"; Daystoload=500; integer i; for i = -2 to 0 step 1 do set stochrsi = 8, 8, 5, e; if stochrsi(i)>30 and stochrsi(i-1)<30 then println symbol , ", ", stochrsi(0); endif; next i;

'nuther question....what is the easiest way to run a scan on a previous date? Others have answered, so I won't go into detail here, but I've found that when I write my scans, I almost always do something like this; integer today; today := 0; ... if (someIndicator(today) > someIndicator(today - 1)) then ... and so on. The point is that I write most of my scans in terms of "today". That way, if I need to go back and check something from a previous day, I can simply change the today := 0; line to today := -2; // 2 days ago and everything works as expected. This has saved me lots of time; others mileage may vary.
