If a first condition is met then I am looking for the second condition to occur within 30 bars.

First condition:

CountTrue(c<c4,9)=9 

Second condition:  

CountTrue(c<l2,x)=13, where x only looks back to when the original condition was met (+4).

I am assuming that I need a counter.

This may or may not be what you want, but I will need significant additional clarification from you as to the actual intent of the question if it is not correct.

(CountTrue(C < C4, 9) = 9 AND CountTrue(C < L2, 13) = 13) OR (CountTrue(C1 < C5, 9) = 9 AND CountTrue(C1 < L3, 14) = 13) OR (CountTrue(C2 < C6, 9) = 9 AND CountTrue(C2 < L4, 15) = 13) OR (CountTrue(C3 < C7, 9) = 9 AND CountTrue(C3 < L5, 16) = 13) OR (CountTrue(C4 < C8, 9) = 9 AND CountTrue(C4 < L6, 17) = 13) OR (CountTrue(C5 < C9, 9) = 9 AND CountTrue(C5 < L7, 18) = 13) OR (CountTrue(C6 < C10, 9) = 9 AND CountTrue(C6 < L8, 19) = 13) OR (CountTrue(C7 < C11, 9) = 9 AND CountTrue(C7 < L9, 20) = 13) OR (CountTrue(C8 < C12, 9) = 9 AND CountTrue(C8 < L10, 21) = 13) OR (CountTrue(C9 < C13, 9) = 9 AND CountTrue(C9 < L11, 22) = 13) OR (CountTrue(C10 < C14, 9) = 9 AND CountTrue(C10 < L12, 23) = 13) OR (CountTrue(C11 < C15, 9) = 9 AND CountTrue(C11 < L13, 24) = 13) OR (CountTrue(C12 < C16, 9) = 9 AND CountTrue(C12 < L14, 25) = 13) OR (CountTrue(C13 < C17, 9) = 9 AND CountTrue(C13 < L15, 26) = 13) OR (CountTrue(C14 < C18, 9) = 9 AND CountTrue(C14 < L16, 27) = 13) OR (CountTrue(C15 < C19, 9) = 9 AND CountTrue(C15 < L17, 28) = 13) OR (CountTrue(C16 < C20, 9) = 9 AND CountTrue(C16 < L18, 29) = 13) OR (CountTrue(C17 < C21, 9) = 9 AND CountTrue(C17 < L19, 30) = 13) OR (CountTrue(C18 < C22, 9) = 9 AND CountTrue(C18 < L20, 31) = 13) OR (CountTrue(C19 < C23, 9) = 9 AND CountTrue(C19 < L21, 32) = 13) OR (CountTrue(C20 < C24, 9) = 9 AND CountTrue(C20 < L22, 33) = 13) OR (CountTrue(C21 < C25, 9) = 9 AND CountTrue(C21 < L23, 34) = 13) OR (CountTrue(C22 < C26, 9) = 9 AND CountTrue(C22 < L24, 35) = 13) OR (CountTrue(C23 < C27, 9) = 9 AND CountTrue(C23 < L25, 36) = 13) OR (CountTrue(C24 < C28, 9) = 9 AND CountTrue(C24 < L26, 37) = 13) OR (CountTrue(C25 < C29, 9) = 9 AND CountTrue(C25 < L27, 38) = 13) OR (CountTrue(C26 < C30, 9) = 9 AND CountTrue(C26 < L28, 39) = 13) OR (CountTrue(C27 < C31, 9) = 9 AND CountTrue(C27 < L29, 40) = 13) OR (CountTrue(C28 < C32, 9) = 9 AND CountTrue(C28 < L30, 41) = 13) OR (CountTrue(C29 < C33, 9) = 9 AND CountTrue(C29 < L31, 42) = 13) OR (CountTrue(C30 < C34, 9) = 9 AND CountTrue(C30 < L32, 43) = 13)

Thanks.  It appears to be more of a sludge hammer approach than I anticipated, but it works.

It uses "brute force" and checks every possible combination individually because x needs to change in the second condition for each of the 31 possible places where the first condition could be true.

I prefer "sludge hammer" to "brute force" but that's just me. LOL. 

PCFs ain't always pretty, but in Bruce's hands they become an art form. :)
