CountIf Question

Looking for a better code to use than CountIf.

Say I want to see if the last 8 bars are all "Up" bars then CountIf doesn't really work very well. It only checks to see if within the last X bars Y of them meet the criteria.

 

Code

// If in the last 10 bars we have had 8 up bars then go long if (CountIf(() => Close[0] > Open[0], 10) > 8) EnterLong();

The number of bars to check must be greater than the number that meet the criteria. In the example, the number 10 must be greater than 8.

I want to see if all the bars meet the criteria. Yet when using CountIf I cannot set both variables to 8.
