之字形系统 (Zigzag System)

Hello,

i have a simply idea for an automated system... but my C++ is very terrible
i think it can a very good system to trade pairs

the idea behinde the system is the zigzag-indicator who plotted the "lasthigh and lastlow" in the chart... see my indicator -> "AF Zigzag Line in Chart"

Now i write a automated System.. see "AFHS ZigZag" -> but it doesn`t work

can anyone help to complete the system?
