If you just need a Zig Zag indicator, then a
Peak, Trough condition will identify the actual peaks and troughs.
Using Valuewhen() and Last value(), I think you
should be able to pinpoint the exact data point.
If you want to draw a trendline between two
points, like a low and a high, then this method will do.
aplitude = H - L
time = bars between the two data
points,
slope = aplitude / time
then keep adding the slope to the previous value,
will give you a trendline connecting hi to lo.
