Mike,
1. Yes.
2. % means the change of ARRAY. it can be any array not necessarily close.
The algorithm is that the reversal happens if price movement exceeds % change.
The main problem is that algorithm needs to know FUTURE price movement to
make the decision if it should reverse or not. That's why you should NOT build
trading systems on Zig, Trough,Peak
I posted some time ago a JScript implementation of zig on this board.
3. Trough/Peak functions are Zig-based. Trough Peaks are points where Zig reverses.
Best regards,
Tomasz Janeczko
