Trigram (I Ching)

This script generates a Trigram for the current candle at its close.

The idea is simple. It takes the current candle close and the two previous to generate the lines of the Trigram.
In traditional I Ching practices, these are built bottom up. So in this case, the Candle in 2 bars back is the base, 1 bar back is the central line and the current close is the top.
Up candles are yang lines, down candles yin.

Anyways, not sure what use it is yet, but if there is anyone else out there interested in I Ching, Yin/Yang theory and trading, this is for you.
