I am having a hard time understanding these formulas.  I am looking for a formula that will return results for any stocks that have moved UP 30% or more within the past 5 days including the current day.  I think this would be simple to figure out but I can't figure it out.  Thanks.

The start of the process would be to define what you actually mean by stocks that have moved up 30% or more within the past 5 days. Here are three possibilities, but there are a lot of other possible interpretations.

If you want the current price to be at least 30% more than the close of 5 bars ago:

C >= 1.3 * C5

If you want the current price to be at least 30% more than the lowest low during the most recent 5 bars:

C >= 1.3 * MINL5

If you want any of price to have been for sure 30% above any previous price during the 5 bar periood up until that time:

C >= 1.3 * MINL5 OR C1 >= 1.3 * MINL4.1 OR C2 >= 1.3 * MINL3.2 OR C3 >= 1.3 * MINL2.3 OR C4 >= 1.3 * L4 OR H >= 1.3 * MINL4.1 OR H1 >= 1.3 * MINL3.2 OR H2 >= 1.3 * MINL2.3 OR H3 >= 1.3 * L4 OR H >= 1.3 * O OR H1 >= 1.3 * O1 OR H2 >= 1.3 * O2 OR H3 >= 1.3 * O3 OR H4 >= 1.3 * O4 OR H5 >= 1.3 * O5

Note that this can still miss instances where price was up at least 30% at some point, but this is because there is no way to tell if the high or low of a particular bar came first.

The formula follows from the definition.
