Louis:

TJ thought of that. Instead of using "X" which updates all the fields OHLC at once, choose to update "C", "H", etc. with what you want.

Hope this helps,

Joe

Allows you to create composite indicators with ease. More info...
Parameters:
array - the array of values to be added to "field" in "ticker" composite symbol
"ticker" - the ticker of composite symbol. It is advised to use ~comp (tilde at the beginning)
newly added composites are assigned to group 253 by default and
have "use only local database" feature switched on for proper operation with external sources possible field codes: "C" - close , "O" - open, "H" - high, "L" - low, "V" - volume, "I" - open interest, "X" - updates all OHLC fields at once

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.
