trend lines v1 nguyenquy

The idea is to find Pivot Highs (PH) and Pivot Lows(PL) first.

Then, If current H is smaller then previous H (means no new higher high and possible downtrend) then draw trend line using them. and also it checks previous trend line (if exits) and if current angle is smaller then don't extend previous one.

Same idea when using Pivot Lows, If current L is higher then previous L (means no new lower low and possible uptrend) then draw trend line using them. and also it checks previous trend line (if exits) and if current angle is smaller then don't extend previous one.

Optionally style of old trend lines drawn as dashed.

Hope you enjoy it!
