Scan combining the " and " and " or "

Below is part of a larger scan. I am trying to compress the larger scan because I have used all of the allowed characters. Below is the first part of the larger scan and it won't work. I think that it's because I don't know how to properly use brackets while using the "and" and "or"? Probably very confusing but I would like for the first sentence to be the constant and then each of the 4 sentences below to be used separately in conjunction with the first sentence. I think that the "and" at the beginning of the second sentence is where my problem lies?

    I think you placed your "or" incorrectly.

    The generic format for an or statement with compound conditions would be :


    and

    [ // opening bracket for "or" statement

    [ // alternative 1

    [condition 1]
    [condition 2]
    [ ... ]

    ] // end 1

    or

    [ // alternative 2

    [condition 1]
    [condition 2]
    [...]

    ] // end 2

    or
    ....

    ] // closing bracket for or statement

    Also, you can eliminate a lot of characters by accepting the default format for the daily timeframe, which is no time frame modifier. (e.g. close, vs. today's close)

    Finally, don't be afraid to use white space and plenty of lines. It makes things much clearer if every "and" gets its own line. That also makes it much easier to test for errors by placing "//" in front of the line to block the scan engine from executing it.

    This version of your scan gets 18 hits on the sp500.
