How would it a condition be written that checks

X number of consecutive higher high and higher low bars in a row - each bar closes > open

X consecutive Lower high and Lower low bars in a row - each bar closes < open

And same to say Minumum rather than define the exact # of bars

If you want to count the number of higher bars in a row, you would use something like the following.

TrueInRow(C > O AND H > H1 AND L > L1, 20)

That just returns a numeric value which will run from 0 through 20. If there are 50 bars in a row, it would still return 20.

So let's say you wanted to check for exactly 3 bars in a row (not 2 bars and not 4 bars).

TrueInRow(C > O AND H > H1 AND L > L1, 4) = 3

If you wanted to check for at least 3 bars in a row.

TrueInRow(C > O AND H > H1 AND L > L1, 3) = 3

Just reverse the > signs into < signs to reverse directions.
