Trendline dynamic changes  [SOLVED]

From the MC supplied indicator "Trendlines_Automatic" is this piece of code:
Does the above code dynamically change the end point of the trendline?


If you do this code: are you creating a new trendline or overwriting the previous one? What I need is to understand how to change vs. how to create trendlines and how persistence of trendlines works?

From the MC supplied indicator "Trendlines_Automatic" is this piece of code:

Code: Select all

m_uptlref.Value.End = new ChartPoint(Bars.Time[0], m_uptlref.Value.PriceValue(Bars.Time[0]));

Does the above code dynamically change the end point of the trendline?

Hello tradetree,

That is correct.

If you do this code:

Code: Select all

m_uptlref.Value =
DrwTrendLine.Create(
new ChartPoint(m_swlotime[0][((m_index.Value))], m_swloval[0][((m_index.Value))]),
new ChartPoint(m_swlotime[0][0], m_swloval[0][0]));

are you creating a new trendline or overwriting the previous one?

This code creates a new trendline.

What I need is to understand how to change vs. how to create trendlines and how persistence of trendlines works?
