Yves,
I think that there may be a misunderstanding on how Zig works. The second parameter that you pass to the Zig function is the minimum percentage retracement before a new pivot will be recognized.
For example; If you said Zig(Close, 5), then a new peak can only occur once Close has climbed *at least* 5% above the last trough, it may ultimately climb to infinity, but it must be at least 5%. Similarly, a new trough can only occur once the Close has fallen by *at least* 5% since the last peak, it may ultimately fall as much as 100%.
Now, consider that when you have fixed the valid range to be between 900 and 1100, then the largest move possible is 200.
Note the following:
200/900 = 22.22%
200/1100 = 18.18%
Therefore, if you try to pass any value greater than 22.22 to Zig, you will *never* get a new peak, since YL can never be greater than 1.2222 * 900 = 1100.
Similarly, if you try to pass any value greater than 18.18 to Zig, you will *never* get a new trough, since YL can never be less than (1 - 0.1818) * 1100 = 900.
Ignore Zig for a moment, and describe what it is that you want to happen.
