Hi,

I'd like to use this formula to create a custom index, but I would like to remove the bars after 3:45PM and before 9:45 AM. Anyone can tell me how to do this?

Thanks,

Louis

p.s. Here is what I tried, without any success:

   /* AddToComposite statements are for Automatic Analysis -> Scan */
    /* add Close price to our index OHLC fields */

IIf( TimeNum()>094500 AND TimeNum()<154500, AddToComposite(Close, "~MyIndex", "X" ), 0)   ;

    /* add one to open intest field (we use this field as a counter) */

IIf( TimeNum()>094500 AND TimeNum()<154500,    AddToComposite( 1, "~MyIndex", "I" ), 0)   ;

    Buy = 0; // required by scan mode

    /* this part is for Indicator */
    Graph0 = Foreign( "~MyIndex", "C" )/Foreign( "~MyIndex", "I" );

Hi Mike,

What I got from that link is this:

   /* AddToComposite statements are for Automatic Analysis -> Scan */
    /* add Close price to our index OHLC fields */
    AddToComposite(Close, "~MyIndex", "X" );

    /* add one to open intest field (we use this field as a counter) */
    AddToComposite( 1, "~MyIndex", "I" );

    Buy = 0; // required by scan mode

    /* this part is for Indicator */
    Graph0 = Foreign( "~MyIndex", "C" )/Foreign( "~MyIndex", "I" );

The problem with this code is that it only shows the close. Would it be possible to get a custom index with opening, close, high, low, volume for the stocks I would choose?

Thanks,

Louis

Louis,

I answered your earlier post in message 120865. I believe that
Example 1 from the first link of that post is what you are looking
for.
