Gann Wave indicator

Hi Good day,

I need the indicator of price movement as Gann rules.

Move up: high price > previous bar high

         & low price > price of begin of the wave

Move down: low price < previous bar low

         & high price < price of begin of the wave

if the large outside bar break the begin of the wave, add another wave along that broke candle (large outside bar)

inside bar: the move will be decided by the last price breaks the high or low of that mother bar.
