what function should use if want to choose 4 out of 7

[LONNV]

I have this 7 value

example

 A,B,C,D,E,F,G

if value of A,B,D,E is more than 1 (or)

if value of B,D,E,F is more than 1 (or)

if value of C,E,F,G is more than 1

I mean when any 4 value out of 7 > 1

how can made this condition by mql4

thanks

1. If you don't need to differentiate A-E vs C-G. Just count them.
2. If you do, test A-E. Then add F and test. Then add G and test.

3. You haven't stated a problem, you stated a want. Show us your attempt (using the CODE button) and state the nature of your problem.

An easy way could be to create an array of 1's and 0's and simply add them up - if the total == 4 then the condition is met.

Script attached as example (sorry it is MQL5 - I do not have  a MQL4 environment, but I hope it helps)
